Speaker Impedance Matching (Connecting Multiple Speakers Properly)

An example of how you can properly connect multiple speakers to your amp properly with impedance matching. This video uses 8 Ohms as an example.

[@Mudge07]

For parallel , 1/Rtotal= (1/R1+R2) + (1/R3 +R4); which is 1/8= 1/16 + 1/16, where the 16 = 8 + 8 in series., simples.

[@wilsjane]

True, but is is even more complex, since the inductive component of impedance does not follow the same formula. For large systems, mixed impedance speakers are normally transformer coupled.

We are going to re wire the 8 speakers in our bar using this really useful diagram. Thank you x

no no let be far guys & gals he as a very good point , and usefull

[@michael6692]

it bloody works up the over priced amps

[@pareshganvir.12290]

Thank you

[@seanburcher7485]

well this was useful, I got four sets of four totalling 16 and I have had this wrong for six months now! its lucky 8/16 units are a surround sound with seperate amplifiers otherwise I would be having to layer series/paralel curcits under other series/parallel curcits and i would be in hell. I agree with the few people on here say that your explanation needs more clarity but minus this you appear to be right, I also double checked with other places to be sure. anyhow, keep doing what you're doing, and thanks!

[@larreetheexhortationist8878]

Good Job partner! I'm doing this exact installation today in a fitness center. I'm using a 430 amp with 7 channels and an ohm rating that goes from 4 to 16 ohms. I'm hooking my 8 ohm Yamaha dual cone speakers up in series and then parallel back to the amp. Since with my application I don't need stereo left and right I'm going to use a mono 3.5mm plug to get the same signal (sound up the middle)from my sound source into the amp then out to every speaker. Again, good job, this is very easy to follow for those who've never done this.

[@darrellchambers3806]

Thank you for that Tutorial.Very easy to understand,well spoken not rushed.I understood every word and the directions were simple.I hate when there is to much teck jargin..I would like to know if you can or how you can hook speakers together using diffrent OHM,S

[@darrellchambers3806]

Thx for the tutorial. Nice and easy to follow, and very imformative I learned a couple things about impedence that I dident know so thank you

[@kreativmadness4666]

Did you guys fry your speakers after following this tutorial?

[@Delivered0ne]

...cabinet across the back of a 4-door truck & was having trouble getting them all to move together. Some would throw all the way while others wouldn't hardly throw at all. He had two on the far right next to each other, one middle left, 4th far Left end. I simply wired the top coil of far L to top of 2nd right, bottom of far L to bottom of middle. Far R bottom coil to bottom 2nd right, bottom of far R to top of middle, & they all started working & moving in unison together & sounded awesome!!

[@simcHyt]

as a electronic student i really suffered your explanations lol

[@sadistikexekutor1585]

So.. If you're an electronic student can you explain to me, if i have 4x16 ohm speakers connected in parallel, how big should be the impedance on amp?

[@simcHyt]

Ideal amp impedance would be 4 ohms, but it would also work just fine if it was 3 or 6 ohms. Any lower or higher of that could cause damage if played at higher volume for longer time.

[@sadistikexekutor1585]

And if it would be connected as series? Thanks btw.

[@simcHyt]

Venum no problem, dude. in case of connecting in series, the impedance simpls adds. multiply 16 by 4 and there is your answer

[@sadistikexekutor1585]

Sompn Brurl Thanks : D

[@yomo68]

Awesome Video!!! Also I have a question: What if i have 2 8 ohm speakers whereas the output of the amplifier is also 8 ohms. Shall I converge the speakers in series or are better off in paralell?

[@yawarsaeed6499]

Thanks for sharing the impedance matching info. How do I mach the speakers watts to amp watts in the above connection design. Please reply.

[@benitesw321]

This may sound stupid but how would I go about connecting 3 speakers to the right channel? And I mean regular speakers directly to stereo. I have no amp nor subs just want 3 speakers to each channel. Please help! ;)

[@ozwzrd]

Thank Heaven he's not a driving instructor.

[@McIntec]

@bercerobry Let's say you have 10 10 watt speakers and a 100 watt amp. There you would have a matched set of speakers. But lets say you you want to add 10 more, so now you have 20 10 watt speakers. What would happen is because the amp can only give a max of 100 watts it would split the wattage in half. So the speakers would only get 5 watts each. The speakers would still function but you wouldn't get very much sound out of the speaker, and this is obviously a scenario that couldn't be possible unless you had a huge amp or a 70 volt system. Keep in mind the wattage of a speaker is not always what you need to power it. It will run on nominal power.

[@younisibrahim4379]

Hi, nice informative vides indeed! Can you tell me how can I connect 14 Speakers (Bose DS 16F loudspeakers) together. How many channels in an AMP will I need to do it? Any suggestions will be appreciated.

[@SoundSystemDesigner]

YOUNIS IBRAHIM Under the grill of the Bose DS16, you will find a rotary "tap selector". Set it to the desired wattage. We'll assume you've selected 16 watts. Fourteen speakers, set to 16 watts each, gives you a total of 224 watts. You need to find a 70 volt amplifier that produces at least 224 watts per channel. (A mono amp is fine. Most 70 volt amps are mono.) Ideally, you want to provide 20% head room, which would have you use a 269 watt, 70 volt amplifier. An oddly specific wattage, so I would steer you toward a 300 watt, 70 volt amp.

[@barryarnold6603]

Would I Do 8 - 4 ohm speakers the same way? Would it keep 4 ohms? And would a 2 channel or 4 channel amp work better? They are mid loud speakers. 300 watts each@ 4 ohms.

[@tank19768]

I understand your explanation, it was very good but I want to put just two 8 ohm speakers on one channel of an 8 ohm amplifier. Please can you tell me how I do that ? Thanks Julie

[@jamminjh37]

if you are wiring 2 of each speaker in series to each other, the total resistance of the pair is 16 ohms. If you add another set in parallel to the first, the total resistance of the whole circuit becomes 1/(1/16 + 1/16) = 1/(1/8) = 8 ohms.

[@OscarGarcia-cn2pn]

thanks for the vid, i have my set up this way: 2 sub of 8 ohms in one channel and 2 speakers of 4 ohms in the other channel. so the subs converts to 4 ohms and the speakers converts to 2 ohms, my amp runs much cooler since i reduce the impedance in both channels.

[@toheebolorunwa4127]

Great bro

[@piotrekstaszewski7237]

Actually... it's not divided by 2. Ohm's are added when connected in series, but when it comes to parallel connection there's a formula for this : Speaker1 multipled by Speaker2 and divided by speaker1 plus speaker 2, so it's not just by 2 all the time unless both ohm values are exact the same.

[@area51junkyard]

lol... i was gonna correct him too on that issue

[@waynecheshire4018]

Piotrek Staszewski

[@waynecheshire4018]

Piotrek Staszewski I'm hooking up 4 rockford 8" what kind of amp should I buy n how to hook it up to 4 4ohm speakers

[@jerichojoe307]

Piotrek Staszewski I could have sworn before he drew in the wiring that he stated that all of the speaker values were exactly the same maybe the brainiacs that know everything aught to listen more

[@jerichojoe307]

Now the calculation that you described is correct but for the example he was using he was not wrong now yes if he had been using a 8 ohm speaker and a 6 ohm speaker the final impedance would have been different but he was not he was showing an example using speakers of the same value. Edited for speech-to-text correction

[@ralphups7782]

thank you, i understood that and i am a fool.👈👺👀👀 🍌👈😒 you saved me buying a speaker selector switch. rock & roll 🤙

[@ludsat1]

Do you think I should use a line-level 2nd-room output for use with a separate amplifier & switch on the Onkyo-TX-NR636 for zone 2 so that I can keep the 7.1 sound in the main room so it don't drop down to 5.1 when I use the Powered Zone 2 Speakers (for Patio) and another room at the same time ? Very nice video MclnTEC , Thank you for you're time !!!!

[@nealalbert3094]

I have a pair of speakers in 4 different rooms. They are 8 ohms. Can I use the system you described and still use in wall volume controls? I have a Harmon Kardon PM655Vxi amp that says its high voltage, high current. It has High instantaneous current capability and can provide 45 amps of instantaneous current. The amp has a selector to output for 4 ohms and the speakers can be changed to 4 ohms as well.

[@PLINKER]

The wire for between the speakers from one to the other ? Are there not two hook up on the back of each speaker? Do you hook the single wire to the positive side or the negative side?

[@MultiScoffer]

Thank you for the video. I have a 50 watt amp head we have to parallel outputs. I can adjust the ohms from 4, 8, and 16 ohms. I want to connect to cabinets to my amp head. One cabinet is rated at 16 ohms the other at 8 ohms. The 8 ohm has two 300w speakers the 16 ohms two 30watts Therefore, which impedance should I use on my amp head?

[@rastabarwell]

great video. can you please help. i have 2 mid range boxes. each with 3x 8ohm speakers in. is there a method to wire these speakers safely. my power amp is 4ohm load. many thanks.

[@alemon22]

THE OHMS I UNDERSTOOD COULD U TELL ME PLS: THE SPEAKER/S WATTS SHOULDN'T BE MORE THAN AMP/MIXER RIGHT? AS LONG THE SPEAKER/S AREN'T ABOVE THE WATTS AMP IS FINE TO CONNECT RIGHT? ALSO PLS: CAN I CONNECT SPEAKERS SOME ARE PASSIVE SOME ACTIVE AS LONG THE OHMS ARE SAME TO THE AMP AND THE WATTS NOT MORE THAM AMP? ARE ONLY THESE 2 DETAILS WATTS AND OHMS TO PAY ATTENTION TO SO THE SPEAKER/AMP DAMAGE? MANY THANKS I'D REALLY APPRECIATE UR REPLY!

[@r.z.pschoolshenvai5884]

Means I should maintain 4ohm instead of 8ohm right? Thnx buddy!!! More resistance or less resistance should be kept in mind??? Reply plz

[@McIntec]

If both speakers are rated at a nominal impedance of 8 ohms then it will create a total load of 4 ohms connected in parallel. Car audio runs at 4 Ohms. Consumer/Pro audio runs at 8 Ohms. A car sub amp will handle a 2 Ohm load. A Consumer/Pro sub amp can usually handle a 4 Ohm load. Some will even handle a 2 Ohm load. 4 x 8 Ohm speakers connected in parallel = 2 Ohms Nominal.

[@guspavlov8608]

Thanks, that is very helpful and simple. I still have a question.... how to connect 3speakers 8oms instead of 4 ? Is that correct like this: 8oms + 8oms, parallel = 4oms + 8oms (3rd speaker) = 12 ???

[@Sup3rmassiveDeadStar]

Great vid. This helps a lot, but i have a question! What about the wattage?? I have 8 6ohm speakers rated 50W each, what happens with the wattage?? I want to wire all the speakers in my house, and I dont want to kill my stereo.

Hello Buddy, I am trying to Connect multiple output to a Single channel PA Amp (Its Mono amp for mics) . Just say I have a large area to cover and I would like to spread the sound around a bit. What would be the plan to connect something like 6 or 10 speakers this way? The Speakers are 6 Ohm. The Amp is can take upto 4 ohms. Would really appreciate a detailed reply. P.s- I thought abut connecting 2x 6ohm speakers in series, Then connect 3 such pairs in parallel. Would the impedance be roughly 4 ohms? And I have 6 speakers?

[@dongedster]

cool real simple and easy to understand

[@roastedcarrots6023]

Hey dude, I have a denon 2.1 receiver with a left and a right channel with one speaker per channel. Would connecting 2 extra speakers ( 1 extra per Chanel) involve the same thing as you did in the video? And do you have any advise on how to set it up? Thanks

[@markgregory8389]

can you connect mismatched speakers to an amp? or do the speakers always need to be perfectly equal watts and impedance? And if a speaker does show what it's rating is -is there a way to test the rating of the speaker?

[@Delivered0ne]

A series / parallel circuit. All the voice coils were in series with another woofer's coil (8ohm) but all 4 series sets were in parallel (back down to 2ohm) to be driven by a 2400w 2ohm mono Memphis amp. Hey Miguel! - How's Virginia!!!

[@suseendranbalakrishnan6529]

Hi McInTEC, I need your suggestion, I wrongly connected the polarity of the cable from my Spendor S3/5R2 speakers to my vintage Sansui stereo amplifier as follows: As wrongly the 2 Negatives of the 2 speakers were connected to the one channel of the amplifier and the 2 Positives of the 2 speakers were connected to the another channel of the amplifier. One speaker was working and another speaker was not working. I was confused and didn't notice about the wrong polarity for about 15 minutes, then I checked the cable connections and detected the wrong thing. I became panic and sweated like anything. After I made the correct connection the two speakers sing as usual. But.. even though the speakers are now working, still I have some fear. By the wrong connection: Would the cross-overs of the speakers become weak? Did I do the great mistake? How will be the life and health of the speakers? May I keep the speakers for long time?. If it would become weak, that would how much? Kindly let me know about in detail. I am much worried about the thing. If I hear from you as: 'Need not be worried and the things are fine' , then I will be jumping with my transplanted knees! I very much love these small beauties. But, now I am sleepless. Thank you, Regards, Suseendran.

[@arxigos365]

Hello, i want to build 2 speakers 4ohm open baffle and i want to use multiple speakers on each speaker, for example one 12 inch sub, a 8 inch mid-woofer, 2 midrange 4 inch, and 4 ribbon tweeters, i got some power amp enough powerful that can drive them easy but my problem or question are the crossovers, can i use 2 of 3-way crossovers for each speaker?? or is better each speaker to have it's own low pass or high pass crossover?? using 2 3-way crossovers on each speaker is a good idea or i will need second amp to drive each crossover separately ? Thanks in advance, Eddie

[@gondokist]

(for home application) if we use an active subwoofer will it still draw power from the amplifier and still have to formulated first or just plug it in into a pairs of the socket (back L & R maybe) since it already have it own power source??

[@suseendranbalakrishnan6529]

Can it be connected a 16 Ohms tweeter (with the filter capacitor) to the 4 Ohms full range driver? What would be any difference in sound? Is it safe for both tweeter and the full range driver? What the method should follow? Kindly explain? Thank you.

[@jecelabayata-he1vn]

If I have a 1,500 watts integrated amplifier What is the speaker wattage (4pcs per channel) I will used?

[@McIntec]

The wattage of the speakers you should use with your 1,500-watt integrated amplifier depends on a few factors, including the impedance of the speakers and the maximum power handling of the speakers. Assuming that your amplifier is designed to operate with speakers that have an impedance of 8 ohms, and assuming that each channel will drive four speakers in parallel (i.e., the speakers are wired in a series-parallel configuration), then each speaker will receive 1/4 of the amplifier's power. Therefore, each speaker should be rated to handle at least 375 watts of power (i.e., 1,500 watts divided by 4 speakers per channel). However, it's important to note that you don't necessarily need to use speakers with a power handling capacity that matches your amplifier's output power. In fact, it's often better to use speakers that are rated to handle slightly more power than your amplifier can output, to ensure that the speakers don't get damaged if you push the volume too high.

[@Kumbalaa]

Thanks for explain about de amps, but then why the amps burn out (if the input signal and the voltage supply is the correct)? what´s the cause? because one conect speakers with more watts that the amps deliver? as your example 20 10 watt speakers in a 100 watt amp. Thanks for your answer.

[@GloveLover69]

Is this for a car? Or home setup? How would you connect the wires from the amp to the speaker wires?

[@DubaiChannel100]

Nice! It seems a decentralized system? In centralized system one would have maximum of two speakers....In mixed centralized and decentralized one would have many....The sum of the speakers input (watts) has to match the amplifier output (watts) in PA system?

[@AudioReplica2023]

somebody needs some powerpoint for tutorials. lol. nice video bro. thanks for the info

[@battleforevermore]

out of curiosity, multiple speakers does not imply higher volume right? more in parallel implies lower output, more in series implies higher output? So it depends entirely on the type of connection right?

[@Xtn1Insecticide]

Can you run a 4ohm and 8ohm in series and a resistor across one of them so they match volume? I’m trying to find out

[@javlogs07]

I am looking to connect 6 speakers to a Stereo Receiver. (4 on A and 2 on B). The receiver I am considering is a Sherwood RX5502 100 watt RMS Dual Zone receiver. My speaker options that I am considering are either six speakers that are each 8ohm / 100 watt or 8ohm / 80 watts. Is it possible to safely (with quality results) hook these speakers to this receiver? If so, how do you recommend I hook up the speakers? If not, what would you recommend? Thx, Brian

[@dot_boi]

Hey can you help me, I want to exchange my 2 guitar speakers with a single bass guitar or a PA speaker due to many reasons and i have experimented with bass and PA speakers with a guitar head and i like it. but would it be possible to. The amp is designed to run 2 speakers 50watts RMS (100 peak) at 8 ohms(for each speaker) but i want to drive 1 big bass or PA speaker to run at 200 watts peak. the reason why is the music i play and the tuning I play in will damage my guitar speakers at some point and especially bc they are nice eminence speakers. But i really need to know if its possible to use the output designed for 2 speakers to drive 1 single speaker without damaging anything. if it really is possible, what would the speaker wattage have to be and what would the ohms have to be? and would I have to wire it differently? i would like to go a little over the peak wattage such as 50 to 100 watts over the peak to reduce clipping and so i can turn my amp up all the way without blowing the speaker (i rigged the amp with a fan so it doesn't overheat). the combo amp i have is a Crate Dx-212. you can find manuals online everywhere but when i looked at it, it doesn't give you much info about the actual amp itself. this would be a lot of help to me and my band if i could upgrade this amp to drive 1 speaker

[@eduardosuante4078]

What is the total watts of 4 speakers example every speakers have 100 watts if you did that way i mean series and parallel combination

[@McIntec]

The total watts of 4 speakers depends on how they are wired (connected) together. If the speakers are wired in series, the total watts would remain the same as a single speaker, which is 100 watts. However, the total impedance (resistance) of the speakers would be the sum of the individual speaker impedances. If each speaker has an impedance of 8 ohms, then the total impedance of the four speakers in series would be 32 ohms. If the speakers are wired in parallel, the total watts would be 400 watts (100 watts per speaker x 4 speakers). The total impedance would be the reciprocal of the sum of the reciprocals of the individual speaker impedances. If each speaker has an impedance of 8 ohms, then the total impedance of the four speakers in parallel would be 2 ohms. If the speakers are wired in a combination of series and parallel, the total watts and impedance would depend on the specific configuration.

[@jonmair5837]

am i able to wire 4 4ohm speakers to one channel and the subwoofer to the other channel,2 channel amp? whats the best ?series ,parrallel,or parrallel series?

[@playmovingpictures]

All very good but are you audio engineer qualified ? Where do you get your information? Like Amps and speakers are not cheap so I wish the engineers from example Nad would explain these tech issues. I'm not saying your right or wrong. Just saying people would be risking their expensive gear on your say so.

[@drewgazmik1618]

+Bend Em (Moving Pictures roll em) Its simple. and he's right....but on a quick note, if your gear is so "expensive" doesn't it already sound great? most higher end systems these days are super compact like "Bose" or 5-10 +1(sub) channel monsters that are amazing, doing such techniques is mainly to increase the performance of low quality two channel systems that need more room filling sound....and some advice if you do so, find speakers all of the same impedance in different sizes, 1 inch- about 6 inches (depending on the wattage of the amplifier) and make sure the speakers are the same wattage rating, the smaller the speaker the more crispy highs and the bigger the speaker the deeper the lows. and I will always recommend an amplifier with a subwoofer channel, so 2+1 or whatever..Hope I helped out a bit. oh and If you have an old 500 watt amp, connect 6-15 inch(12 inch is most common) speakers in parallel/series. sounds awesome! cheers.

[@jasssa8635]

if you can't explain it well enough then you don't know it well enough

[@cat123abcable]

I'm sorry but if you have 4, 8ohm speakers, that brings the impedance to 2 ohm when hooked all in parallel . The conversion for hooking in parallel is 1 over the sum of all the reciprocalls of impedance. Essentially put 1 over .125X4. 1/.5 is two ohm

[@Jamessawyer010]

Yeah but when you connect the speaker's that way, it also reduces the volume of the speakers too. I got a 500w amp with 5 channels, each channel can handle 4-8 ohms. I wanna know if I can fix a 250w speaker to each channel which has a impendence of 8 ohms. Wouldn't that make a total of 1250w because 1 speaker is 250w. All I wanna know is would that be possible because in the back of my amp it just says 500w and connecting 5 speakers with each 250w would make a total of 1250w.

[@Imbored-aw]

The speakers do not make 250 watts that is just the max rating of how much u can send to them without overheating the voice coil and eventually blowing the speaker do some research before hooking up a system bud but good luck

[@mavicone5845]

What happens if yiu have 4 speakers …. X2 are 8 ohms and x2 are 6 ohms … and the amp is rated 8 to 16 ohms … how do those get wired ? In a series method ? The 8 + 6 = 14 ohm. On the left channel and then repeat for the right channel ?

[@McIntec]

Connect one 8-ohm speaker in series with one 6-ohm speaker on the left channel, resulting in a total impedance of 14 ohms for that channel. Repeat the same for the right channel. This configuration will ensure that each channel of the amplifier sees a 14-ohm load, keeping it within the safe 8 to 16-ohm range specified by the amplifier.

[@anthonydjmajikrush270]

It seem everyone is neglecting the principle of the watts,rather concentrating on the ohms law, 14 speakers definitely needs more than an amp

OK. I got one. I want to wire up a little 4ohm sub to a 2 channel amp with 4ohms per channel. I want to run both channels to the sub and wire up a 4ohm speaker to each channel as well but it sounds like shit wired strait that way (pos to pos, neg to neg). What would be the best way to do this?

[@yamin244]

yo mann..i got 2 speakers of 15W and 8Ohms each and i want to connect them.can i modify it for my pc speakers or mobile using the headphone wires?and how much resistance do i need for it?thanks in advance :)

[@Lifeswicked]

plus i have a home project where i want to run 2 4ohm tower speakers an a 1000w kenwood car audio sub of a 350w 2 channel car amp how can i wire the tower speakers to keep them at 4 ohms. your help would be greatly appreciated

[@gustavopi]

I'm not sure if this will allways work rigth, becouse impedance is not really an electronic resistor, but a magnetic "couter-strike" that only occurs with waves. So connecting speakers in series can make "charges" from a speaker to another and to the amp leading to unexpected (undesired) results. I know it happen with capacitors circuits - you should not connect it in series.

Can you suggest a matching Stereo Power Amplifier for my 2 pcs. of SS GRX30 .. 60 Watts x 3 way speaker SONY Make..with 3 speakers in one box ...15 cms.cone type) + 5 cms. (Cone type) + 2 cms.(ceramic type)...6 ohms...

[@ricardzborbon9905]

hi guys. i want to ask something i am quite confuse about the specs of my amplifier. the specs says 700watts x2 in 4 ohms and 1300 watts x2 in 8 ohms. my question is. is it 700/1300 watts in each channel? or it is the total of all channel.

[@jabezprayer1]

I have a old Yamaha P2100 amp which says on the back 120 volts. I have 10 speakers that have the 70 volt transformer attached to each one. Could I connect 5 per side to this amp?

[@theamiablematt1307]

Hi, Sir! So I have been using our home theater for a year now. I'm currently studying DC circuits on a Computer Engineering program so that's why I have a less knowledge on impedance matching. The scenario is that the home theater runs 5.1 channels with the port of subwoofer rated at 4 ohms. The current subwoofer is a 4-ohm subwoofer at 250 watts. What does it mean by the watt rating of the speaker when the total output power of the amplifier is 1000? The case is that I feel that the subwoofer does not give that much bass. So I'm planning on upgrading my subwoofer to a 14 inch from a 10 inch. I found a 14 inch subwoofer on our nearby appliance store and have it tested. I was beyond satisfied by the bass it gave. The 14 inch subwoofer is rated at 300 watts at 8 ohms. My question is: What exactly will happen if I'll hook it up to my receiver? Will it sound the same as to what I felt on the store? Will it burn the amplifier? Or somewhat, the speaker(the planning to buy, 14 inch)? It's Pioneer that already has a casing. Take note that this subwoofer is a powered one. The one that is needed to be plugged. A detailed help to my problem is very much appreciated, Sir. :) Advanced thanks to you and cheers for your knowledge on impedance matching. :)

[@rebelnut1]

If your reciever is rated for a 4ohm load, hooking up an 8ohm speaker will draw much less power, so you will get less volume, but with a 14 inch, you could just crank the bass and be fine.... essentially, you could hook up another of those speakers in parallel for your 4ohm load, but you would have half the watts going to each speaker...

[@theamiablematt1307]

rebelnut1 Thank you so much for your informative reply, Sir/Ma'am. :) Another question: Will it affect the total output of the amplifier which is 1000W when I'm about to attach a powered subwoofer over the amplifier? Thanks in advance! :)

[@theamiablematt1307]

Active/Powered subwoofer's power will be at 500W.

[@rebelnut1]

TheAmiableMatt Ah very good question. You do not want to hook up an amplified powered signal to a sub that has its own amp. You want the RCA output going to the sub, which is just a small signal for the sub to Amplify. Generally most receivers will have a "pre amp out", which, is what your looking for. Don't just take my word for it. I'll shoot you a link as well. hometheater.about.com/od/loudspeakerssubwoofers/qt/Passive-Subwoofers-Vs-Powered-Subwoofers.htm Edit: Almost missed the question about final power of the amp. Since your sub has an amp built in, you will be taking 0 of the wattage from the receiver. Which ultimately can be better, because now it's not working so hard and can provide a cleaner signal to the rest of the speakers in the system. You may need to power that sub on a different outlet. Sharing the same one "could" cause you to trip a breaker.. I'm not saying it will, but keep that in mind. Hope your build goes well, plan to share it on youtube?

[@theamiablematt1307]

rebelnut1 Great! Saw it at the back panel of our receiver. I could nearly bust out everyhting if it wasn't for you. Thanks, man! :) I though it would be the end of world to me. LOL!

[@SunilVerma0161]

Can u make a video..or/ advise how to connect INTEX IT4850 5.1 MultiMedia Speakers to computer... i am unable to connect..

[@rebelnut1]

Good job bud, a little rough in some of the descriptions but over all very well done. Oh, and how funny are the comments, "its not 1 ohm"... haaaa. Each speaker in parallel drops impedance by HALF. So, 1 speaker starts off with 8ohm, 2nd in parallel is 4ohm, 3rd in parallel is 2ohm, 4th would be the final for 1ohm when all speakers are in parallel. Thus his tutorial, why you need to know how to wire series, or series / parallel.

[@SoundSystemDesigner]

rebelnut1 It actually is not 1 Ohm. Parallel impedance is calculated using the inverse of the sum of the reciprocals of the speaker impedances. It is not a simple half-ing as you suggest. Three 8 Ohm speakers wired in parallel is actually 2.6 Ohms. Four 8 Ohm speakers wired in parallel is 2.0 Ohms.

[@rebelnut1]

SoundSystemDesigner My apologies, you are correct. www.eminence.com/support/wiring-diagrams/

[@jerrybryant5052]

Well, his demo is to help people not to uplift himself as the greatest and make fun of everyone else trying to save money and diy

[@neilbantugan]

how about the wattages of the speakers? i mean i have an amp that says 500 Watts x 2 RMS. If i connect 8 speakers the same way you did on this video, what are the wattages of these 8 speakers to cope with the specs of my amp? thanks sir !

[@AdaKurFireworks]

[@ihifidenmark3805]

Neil Bantugan The power handling of the speakers would just double.

[@neilbantugan]

so, 1000 W x 8 speakers at 8 oms?

[@neilbantugan]

or 250 watts each?

[@ihifidenmark3805]

Neil Bantugan If you have 8x250W 8 ohm speakers you will be making pairs of parrallel speakers means that you will get 4x500W 4 ohm but you serialize them into two pairs so you get 2x500W 8ohm

[@cardingkidlat9775]

Hi sir good day we have 75 speaker 8ohms What type of connection you recommend

[@toheebolorunwa4127]

,75 is way much for one amps,you will be needing enough Amps,and cross over,well,since its a lot,you will definitely need to connect the amps in series as well,that I suppose answers your question

[@r.z.pschoolshenvai5884]

I want to connect custom woofer which has more watt than original I am connecting both custom and original together to home theater Will it effect amplifier?? If yes how should I connect two subwoofer of unequal power

[@McIntec]

Connect them in parallel. The amount of total wattage is the wattage of both speakers summed together. Remember to keep in mind RMS and peak wattage.

[@MrMegaismo]

If i have three 4ohm speakers on both right and left side and a 4ohm 2-channel amp so how can i connect the three speakers in series? Or is it only possible with four speakers?

[@smedz5937]

+MrMegaismo Im in same boat man, i wanna run 3 speakers on right n 3 speakers on left, all speakers are 4ohm.. n from here im stuck on what amp to get n how to wire it :(

[@Kalyan553]

Interesting. What happens to the positive wire of the top left speaker and the negative wire of the speaker below ?

[@McIntec]

+Kalyan553 it connects to your amp

[@atlanticcomputerssupplies1565]

NICE AND SIMPLE....

[@henryprzewodowski3689]

How do you match or add speaker watts to match amplifier capacity when attempt to match speaker impedance. Why does everyone always talk about impedance ohms only?

[@jamminjh37]

One note: If all four speakers on one channel are wired in parallel, the total resistance on that channel is 1/(1/8 + 1/8 + 1/8 + 1/8) = 1/ ( 1/4 + 1/4) = 1/ (1/2) = 2 ohms. The formula for calculating resistance in a parallel circuit is 1/ ( 1/r1 + 1/r2 + .... + 1/rx).

[@baler18]

Hey, i got a question, in ur example u combines 8 (8Ohm) speakers. Is it possible to combine: - 2 (8Ohm) speaker - 2 (6Ohm) speaker - 2 (4Ohm) speaker thanks

[@badboycris]

nice video man.

[@McIntec]

@jabezprayer1 120 volts? Are you sure your not mistaken that for the A/C power? Most amps that have transformer terminals for speakers (in North America) are 70 volts. Apparently there is amps that have 25 volts but I have never come across them. In other countries there are amps that have 100 volts or more.
