The RIGHT WAY to wire subwoofers to a monoblock amplifier

If you are installing a subwoofer for a custom car audio system you are likely using a single channel "monoblock" amplifier. Some of these amplifiers will have two sets of output connections. Why is this? Do we need to use two subwoofers? Do we need to bridge the monoblock amplifier outputs? How do we wire one subwoofer to a mono block amp? Let's explore!

I am so happy that you made this video. As a car audio installer, I had a couple customers that were unwilling to take my word, even when I showed them the exact demonstration of continuity that you showed, that I had correctly installed their amp. One guy was absolutely convinced that his subs were only getting half the power because he was only using half the amp. I think that at my boss's direction I actually ran a second set of speaker wires to his box just to apease him. My MECP advanced certification wouldn't convince these people that I knew what I was talking about, but I bet that a popular KZbin video that confirmed it would do the trick.

[@CarAudioFabrication]

Happy to help! I don't know why guys always feel like the car audio shop is trying to pull one over on them... although I did have a guy today comment that "he's only recommending fuses because he sells them, you don't need fuses on wiring" so guess us YT guys can't be trusted either... 🙄🙄🙄

[@xxxYYZxxx]

Use 4-channel home-audio wire, with 4 wires wrapped in a single cover. That way you can use both both connectors on the sub amp, plus whatever gauge fits exactly, times two, is likely thick enough. Your less observant customers will think the 4-stranded wire was specially made for sub amps. 🤣

[@m1ndphaser]

yeah just add that second pair of wires, a 4-terminal plate and connect two wires to the air inside the box lol. remember, 15 minutes on youtube means you know more than experienced techs :)

@@umtbozkr2358 I mean, the Amp has to stay cool but I guess if it's loud enough to hear, it can be annoying. I've used cheaper Amp before and the fans were audible and always on, but on my Audiocontrol or Phoenix gold, never really heard them.

@@umtbozkr2358 d 1200 fan runs w amp. Quietly, notic d the amp gets warm w no load even. Likely why.

[@umtbozkr2358]

@@dwilde649 I’m sorry, didn’t understand your comment D Wilde. The amp works perfect and delivers a good performance. Only the fan is constantly on and it’s not the most quiet fan. Normally I ran my woofer with a bridged Steg K2.03 with about 1000w RMS. When the fan went on you couldn’t hear it running. I replaced it by the Audio Control because it draws less current because it’s a class d amp. A class d amp shouldn’t get that hot; even without any load it gets hot.

[@Waveboarder7]

I had to google this 2 hours before you uploaded for a Mosconi 1000.1, funny coincidence. You gave a lot more detail than the answer I found earlier, thank you!

[@Pulverrostmannen]

There is actually one major advantage to bridge or use both the outputs on the dual that you did not mention, I would always bridge or use both outputs always if possible, why? it is very simple, This speaker block is internally connected on the PCB, if you use one pair you gonna push all load through 2 solder connections instead of 4, I had amps where this load got so high the joints exploded and the amp failed due to overload on these. if you use both outputs you gonna share the load on the terminals making such failure case much less prominent. However this applies more to cases when you load the amp with lower impedance thus making more current. But I had amps fail before I always started to use the terminals with all available outputs. you would actually gain a tiny but more power too as the resistance get slightly lower. I competed in audio a lot before and this is why I know. Every watt counts

[@xxxYYZxxx]

Great point, and 4-channel home audio wire could solve the issue, eg 4 wire. Doubling the wires reduces the total AWG by 3, making it feasible to use a speaker wire (eg, 16 awg) that actually fits instead of trimming or using special tips to fit a monster sized wire, plus both connections get used. The 4-channel wire is better than 2 runs of wire, as the wires are bound into a single cover, minimizing impedance fluctuations.

[@Pulverrostmannen]

@@perk28 great to hear your feedback about this! Bassheads unite!

[@Spacecadet3890]

Running to a dvc what advantage of running 4 conductors? Instead of just jumping them in my box that little bit less resistance will be made up by another 2ft chunk of wire

[@Pulverrostmannen]

@@Spacecadet3890 The biggest benefit is that you reduce the load on each terminal since you run less current through each wire and terminal as they split in half you will have more power and less heat produced in the interconnects and wires. But in low power amps it gonna be a pretty small amount. I had an amp with more than 1KW power explode the solder joints on the speaker terminal because it was too much current for one single output. So it is just a matter of caring about your stuff but either way you connect is still gonna work unless it can’t handle the power in the long run

[@TE5LA-GAMING]

They are typically just bussed at the terminal with only one pair going to the board, so it wouldn't matter.

[@fordsixhoe1184]

Man, what I do without your videos....

[@brotherabid]

Your correct about the amp, but with the Sub not all the terminals need to be connected if you want to run 4ohm, 2ohm or 1ohm etc

[@CarAudioFabrication]

Sounds like you didn't watch the video

[@TE5LA-GAMING]

The additional terminals are for convenience. It can also be that they use the same case for 2-channel models so the strip is already there.

[@joelchery6411]

Hello Mark. First of all, I thank you for its contents, and I have a question for you (I have 4 speakers of 8 ohms of 480 voltage of each and one 6*9 low) what kind of amplifier should I use for my car without affecting anything. Please

[@TE5LA-GAMING]

Makes no sense. What is "480 voltage"? If you have 5 speakers total, use a 4-channel amp. Wire the 8-Ohm speakers in parallel, 2 to a channel. This gives 4 Ohms. Bridge the other two channels to the 6x9. Set the xover to LP of the 6x9 channels and to HP for the high speakers.

[@ChitoWorld]

My kicker 1200 amp has two positive on the left n two negative on the right . I connected positive to the middle positive n negative to the middle negative . I was starting to think I needed to connect the positive the far left positive n negative to the middle terminal.

[@mildaudiophile3879]

This is actually a very informative video.

[@julesbruchez-outperformtra2020]

I have question that I would like your opinion on. Just so we are clear ALL variables are equal in this situation. Question - Is it more efficient to run two Amps separately on two separate subwoofers? Or is it more efficient to run one large amplifier on both subs? So we are clear. Two Alpine subwoofers that EACH take 400 RMS. On two 400 RMS Alpine amps or one 800 rms Alpine amp?

[@peytonscoggin3746]

It makes no difference where the power is coming from all the subs see are power. Does not matter if it is one amp or two. The only difference it makes is on audio signal. You cannot run 2 different signals to two amps because they would play at different timing. Just run one audio signal to the input on amp one and then use the audio output on amp one to the input on amp two. So the audio signal is linked. Just make sure your amp has an audio output :)

[@peytonscoggin3746]

@Pasler Andrew I was saying more for someone that might be using 2 5-channel amps and that 5th channel on each amp for each of your subs. They are identical amps with the same about of “efficiency” and power

[@TE5LA-GAMING]

​@@peytonscoggin3746Actually, it does. Separate amps have separate power supplies, so this may be an advantage unless you assume the single amp has twice the power supply.

[@benbentley89]

I am using a powered sub and now my radio doesn’t have any sound coming from the speakers how do I fix it so it works properly

[@vamodizer]

Hi! What about the inputs? Does I need to input the left AND the right channel or one channel is enought??

[@anthonyreed5767]

Quick question. The cable that connects the gain control switch to amplifier is too short to reach amplifier. What type of cable can I use instead of the one provided in my amplifier install kit? Looks like a 6C6P or Cat6 ethernet cable.

[@TE5LA-GAMING]

You must have a hella long vehicle. I usually have to bundle six feet of cable because they are so long.

[@kylelearn7839]

Is it possible to wire two 4 ohm DVC down to 2 ohm impedance?

[@TE5LA-GAMING]

No. It can be 1, 4, or 16.

[@giosant5327]

I have a mono amp with L/R INPUT and the signal coming from dsp has 1 rca coming out should i use a split rca cable?

[@nashs2373]

What is the best connector for subwoofer quick disconnect?

[@xenopac]

I got two kicker ten inch to ssl amp I got it hooked up right I get a wining sound when I press the gas on my car

[@TE5LA-GAMING]

Buy a real amp. Doesn't it have a low-pass crossover? You should never hear an alternator through a crossed over sub.

[@valecasillas5729]

Can I put 4 gauge to this amplifier power cable or 0 gauge?

[@mr740]

So, in theory, lets say you have a 2 ohm single coil woofer with built in wires that are too big for the connectors of the amp you are running ( and probably needs more power than the amplifier can push, but thats beside the point). If one was to machine som adapters that would accomodate those wires and be screwed in to the amp, that would share the load onto the solder points on the PCB? sort of like a Dual 1/0 AWG to 1/0 0 Gauge amp inputs but more fancy to not come into contact with each other?

[@Avaddon911]

There are some amps that conveniently put the positive terminals on one side, negative terminals on the other. So adding an adapter like this is much easier. But if it's configured like the amp in the video it's going to be hard to do.

[@TE5LA-GAMING]

I think you'll find that most amps simply jumper the extra terminals at the block, rather than run separate wires back to the PCB.

[@pixelgaming6843]

On a dual voice coil sub can you run short wires between both negative terminals and positive terminals. Then run a single neg/pos to the amp?

[@johnj2496]

Yes you can or do like he was showing and run 2+ and 2- wires to amp so the wire won't limit power but it might not be even a noticeable difference. So it's bridged but kinda like 1 dual coil Is wired like 2 speakers. Either way works. 4 wires would be able to transmit more power But if the 1+ 1- and jumper wires aren't limiting ie maxed out then there wouldn't really be a benefit to the 2 more just It's like the 2 outer tires on a dullay truck when there's no load sure there's potential but not really needed when it's empty

[@ijonnypro]

So if I have dual outputs on my amp & 2 4ohm subs. Are you saying wiring both separately to 2ohms then connecting both pairs of each subs pos & neg wires to the amp directly will result in a 1ohm final load? Which essentially is wiring them in parallel but through the amp instead? Really need this answered. My box’s port is in the middle & I don’t want to drill a hole to wire them together if I don’t have to 😢

[@kushmade1]

Same I don't know why I can't find this anywhere.

[@ijonnypro]

@kushmade1 I figured out the answer on my own; the answer is yes; you can wire two 4ohm subs individually at 2ohms, then connect them to the amp (if the amp is a monoblock) & the final load will be 1ohm. The speaker out terminals aren't two separate channels, but most monoblock amps offer an extra set of terminals for this exact reason, convenience. Hope this helps, man! :)

[@TE5LA-GAMING]

​​@@ijonnyproYou can't wire a 4 Ohm sub to 2 Ohms unless it has dual voice coils, which you didn't specify. If you're saying wire two single VC 4 Ohm subs together to get 2 Ohms, yes, but it is still 2 Ohms on a mono amp. It would only drop to 1 Ohm on a bridged 2-channel amp.

[@johnmerebanog3809]

The jumpers in mono is like Bridge mode in power amplifiers. Is it the same?

[@TE5LA-GAMING]

Mono and bridged are not the same. You can have two separate channels running mono without them being bridged. Mono combines stereo signals into a single (mono) signal.

If you are blowing a 2700 watt speaker, you have either an amp with too little power, or a very poor speaker enclosure. I looked up that amp. It's only 200 watts. It claims 500 at 1 Ohm, but I'd say this is highly unlikely. A 3500-watt amp would need two zero gauge power wires.

HOW DO YOU REBOOT OR RESET AN LC1.800 OR USE THE JUMPERS ON THE INSIDE OF THE AMP

[@carlosberrios1021]

Does it work for all class D Amps with 2 channels

[@TE5LA-GAMING]

2-channel amps aren't monoblock. If you jumpered a 2-channel amp like the thumbnail, you'd fry the amp. If you bridge it, load will be 1/2 what the speakers are wired to.

[@xxxYYZxxx]

As this amp is 2 ohm min, the most obvious use is connecting two 4 ohm subs, one to each output, for a 2 ohm load. Four-channel home audio speaker wires could be used with both outputs. 4-channel wire could fit exactly, offering a low total gauge wire, while the 4 smaller wires are less cumbersome around amp outputs & speaker inputs than two thicker wires.

I do not want to put no speaker box in my vehicle just want to take out the original speaker an put other speakers so I was wondering what's the best speakers to use for bass and voice

[@rdwsp]

I'm trying to figure out the connection from the 3317 to the head unit can you please help

[@hgfdksk17]

What size speaker wire is ideal for connected the sub to amp ?

[@jessevargas3289]

depends on subs rated power, but for most people, 12-10 gauge works fine. I use 10 gauge on my sub thats rated for 1000 watts

[@heavychevy4616]

thank you sir!

[@CarAudioFabrication]

Thank you!

[@Kelwof]

hi, did you make a video on how to wire a 4 channel amplifier ? like, i have a rockford p8004 and i want to use the 800Wrms for one single sub, is that possible ?

[@TE5LA-GAMING]

You need a dual voice coil sub and bridge the amp into 2 channels. Wire these to the coils. You will get the 2-Ohm rating if the sub is dual 4-Ohm.

[@raudelflores4935]

Very good explanation !! Thanks

How can i connect two speakers to one terminal

[@TE5LA-GAMING]

Twist two wires together?

[@Blakelikesfood]

Dam...got excited per the thumbnail thinking there was some kinda wiring trick.

[@FranciscoMartinez-kn4wu]

I imagine it has four connections to support a dual voice coil subwoofer… different variables for different setups

[@Cent51]

The bridge port.

How to add an Amp to a Corvette C 7 ?

[@jcmartinez7527]

Nice thumbnail lol. Definitely added another reason to click on the video 🤣

[@CarAudioFabrication]

Always love to give visual examples so folks can better understand!

[@lllllDuBlllll]

@@CarAudioFabricationSo using the two outside terminals is bad? I also bridge my subwoofers 🤔🤔🤔

[@brenthehen2365]

Thx so much

[@rockislandlife6383]

Is it safe to connect an amp at 1ohm to a 2ohm sub?

[@TE5LA-GAMING]

It isn't possible. The speaker determines the load on the amp. How are you going to run the amp at 1 Ohm if the speaker is 2 Ohms?

[@JoshSmith-fn2lk]

I just had a mono amp installed to factory system for a sub by way of an LOC and the installer only tapped the left front speaker for signal. I’m concerned the sub is possibly losing signal as it’s only pulling from one side. Shouldn’t he have tapped BOTH front speakers? Or does it even matter due to the mono amp?

[@Daniel-ju6oy]

You should also tap the right front speaker. There is bass on the right side and other audio information that your amp needs to reproduce proper sound to your sub. Otherwise it will sound like something is missing in your music

[@TE5LA-GAMING]

No, it doesn't matter. Low frequency is mono. In fact, many factory subs are wired this way. It would only make a difference if you balanced the radio all the way to the other side, which is senseless.

[@Daniel-ju6oy]

Why then do they provide a left and right channel input on a monoblock amp if the ultimate output is mono only? On true stereo, the bass can be uneven on the right and left side. Have you ever listened to older music with headphones and you only heard the bass on one side? ​ if your head unit is putting out mono instead of stereo then equal sound is being reproduced on both sides.@TE5LA-GAMING

[@JoshSmith-fn2lk]

@@Daniel-ju6oytook truck back and audio shop said same thing. Guy who installed it had to fix. Plus amp was missing 50% signal input from right side causing it to work harder and not have as much output. Sounds completely different now !

[@aarontate8827]

Are Rockford Fosgate as potent as in the 90's..?

[@donttrip7041]

So does that mean if i wire two 1ohm subs it still will have a 1ohm impedance

[@TE5LA-GAMING]

No, it will be 1/2 Ohm.

[@jamalyellowhair1841]

Question? Is there ONE amp that does both SUBS(2)(skar10"800w) and SPEAKERS(4)(ds18) and tweeter 🤔 -I'm looking @Skar amp 2000?

[@ronniedale6040]

What about the input side? For example it's a mono amp. The headunit has a mono sub output. So why L & R inputs?

[@CarAudioFabrication]

Because most every device that creates the low level signal at a bare minimum will have a L/R signal. You will want that signal summed for your subwoofer so it allows for both in to sum internally.

[@TE5LA-GAMING]

​@@CarAudioFabricationa lot of cheaper head units have a single sub output. You would want a Y adapter then.

[@phreaktor]

Is the old school Rockford 800a2 a mono block or 2 channel?

[@omerrobinson9700]

Thank you so much! How can reach out to you if i have a question?
