Powering Car Amps in YOUR HOUSE!

If you ever wanted to install car amps and audio gear in your house, this is how to do it.
I used a power supply/battery charger unit from XS Power
4xspower.com/shop/charging/in...
And a battery from XS Power to power my amp from Incriminator Audio
www.incriminatoraudio.com/inde...
Switching was taken care of from my Sparked Innovations RBX-4CH

This should have 1 mil views. This is perfect. Definitely gonna do this route at home. Need it for testing my amps, rcas, and subs. Thank you extremely

[@jar1zxrcfun75]

Kinda cool seeing the cerwin vega on the test bench. I remember being a teen when they came out. I’ve got the bigger version of that amp with IA80.1 and have to say that out of all the bass amps I’ve had I like it the best. I’ve got enough stuff in shed to run 500 watts rms but kinda easy just to buy one electrical system for my truck and for home or shed every day listening......the simple plug in a home radio hit power button and have music can’t be beat. Good vid and something like this works great for troubleshooting if you have problems with your car system. Or almost a must if you have friends that are new to car audio and having trouble. You can take amp, sub, radio or anything out of the car and hook up knowing your just getting power and test whatever needed and bypass any problems that could be in the car.

[@jcorpus209]

That’s awesome. I’ve starting to just now get into car audio and I’m already 40 years old. A little late to the game, but this is so cool. Thanks for sharing, you never know who stops by after 3 years from this video being uploaded.

[@jarmanolivares]

I had 2 Fultron 15's at 15 years old in 1994 hooked up to a inverter with my Alpine tape deck and pioneer 4 way 6x9's in my room! The I got the Kicker Comp 12's in a 4th order box...

[@audiofanatic7377]

Great informative video. I'm an old school car audio guy from the early days of the JL AudioW-7 first release. I learned some great points in this video.

[@anubis5071]

If you don't wanna use a battery. I've dome this directly wired to my wall outlet. Computer power supplies work just as well. Currently rumming 2 1,000watt power supplies and 2 850wat power supply. I'm running a 3700 wat mono block amp with a 4 fared Cap. I don't have any power drops even on full

[@tukeskin]

Xbox one power supply works as well for up to 17 amps

[@HifiVega]

Great how to/explainer video!

[@trevorhembruff6569]

You are the first KZbinr that I actually did use the bell for.

[@derbagger22]

I'm not looking for a home audio setup, rather just a test bench for older car audio equipment. This looks fantastic, I'll likely be ordering some products soon....

[@SparkedEd]

Heck yeah, makes for some great test bench setups.

[@robduncan2816]

cerwin vega stroker...ahh those were the days. one of, if not the best sub ever made

[@richbrown5852]

It was super powerful for its time, I remember Adam Rayner testing the dvc 18" model in a warehouse and feeding the sub all that the crown macrotech 5000vz could give...that's a 5k amp...it was quite a thing in the 90s

[@rudejude9725]

It was a system in my buddies bedroom 20 years ago consisting of a power inverter an amp and a sub hooked up to an old Sony bedroom boom box that gave me the audio bug . Before that I had never heard a song with bass like that . I plan on building a powered sub box for my basement with some old parts because I’m old and nostalgic and my mom can’t tel me to turn it down anymore lol . Great tutorial dude I’ll be ordering that relay box thing is sweet

[@SparkedEd]

Thanks man. Yeah I loved my old bedroom setup. I would lay on my sub box filled with cerwin vega XL 12s and pioneer IMPP 8s and take naps to bass.

[@rudejude9725]

Yeah I 4 15’s for a brief moment before the parents decided it was a terrible idea lol

[@eliassurratt5002]

Love how to videos been woundering how to do this for years thank you!!!

[@gxiong3917]

Awesome, Ya get a 👍 for having an ol'school 👊 amp...

[@Teknakill]

This is a wealth of information. But personally I would keep it simple and just mimick a car audio system with just the battery for power (charging it when needed) along with amp and quality speakers with subs and keep it compact and neat. Having car subs for movies in the house is so awesome, it fills the room like hearing thunder, I get hyped just thinking about it.

[@edifierbass7821]

Yes lots of music enthusiast has been doing that using Car audio's on their rooms since 2008 ti'l now and you're doing great also keep it up

[@jasongaudreau2075]

I love it when comments show age. I had a Sony car cd player mounted to the headboard of my “waterbed” back in 1994!!! Sheesh 2008! Haha. Yessir it had 4 6x9 4 ways in boxes mounted on the corners and get this….a “RadioShack” “bass tube” which was an 8” powered subwoofer built in a 2ft tube encloser. It pounded. But my back will never forget that waterbed. Worst invention EVER!!

[@Teknakill]

so epic i love it haha@@jasongaudreau2075

[@UniCrafter]

I use a PC power supply to run a 4 channel amp for a 2.1 setup I've got. The power supply holds its voltage very well, which is awesome for dynamics/transients. It also has multiple voltages out so can be used as a lab supply. I'd say the method mentioned in this video is best though, as nothing really goes wrong if the system is overloaded, the charger won't be over-driven, and the battery's voltage will just decrease. Regarding caps though, for movies/home theatre caps should be fine, rumbles don't last too long, though for music you'd probably want a battery, or even both.

[@SparkedEd]

Both would be awesome if someone was able to put in the money.

[@ninimulaki]

i have almost the same setup, however i add a car preamp wired just for the sub and i can have the woofer bark depending on the music type and mood, (independent of the main music input vol)

[@kman915]

I been doing this since 2006, started off with using PC PSU's. Now, I'm powering my setup with a Kinetik KIPS 12-80 power supply. (80Amps) It does the trick... But, I will need to expand and add a battery, or as mentioned in this video, a supercap for an upgrade in Audio components.

[@thehomelessproject3784]

Thats stroker sub is sweet 👌

[@anandshah71]

[@TheSFFV]

Dude so glad I found this. I was wondering if a power supply and battery would work.

[@jonathansmith4380]

Done it from the math in my head gave out more power than I expected easy no overload or nothing

[@matthewdefer8215]

Same here. I loved car audio before I had a car so I hooked up a band pass with 10inch clarion sub in my bedroom! Lol 1997

[@homsey2011]

Been there done it I use to run 6 12s in my bedroom in the younger years lol it was beast but yeah I realised you don’t need all the crap you have here just a beast of a bench power supply and your done simple

[@water1051]

Same - I’m trying this without the battery. 1KW power supply direct to the amp.

[@finlay230]

excellent vid !!!!

[@morganbills2749]

Hey Ed, I've found that old server power supplies are really good and cheap I can get about 3500W continuous for around $80-$100(which I guess is expensive but when you think about what you're getting its a pretty good cost to power ratio). I'm in the same boat as you were in when you were 12 lol. Can't wait until I get a car and see what it can really do! Great video though didn't think about the batteries.

[@SparkedEd]

$100 is actually a great deal. As a kid I just used what I could find for free. Lol

[@brenyngreen]

I have done this with a 500w pc power supply to power a 1200w 2ch amp to run 2 12 inch subs and another 500w pc power supply to run a 1200w 4ch to run 4 speakers it's one hell of a sound system for my room

[@blueballs8599]

im trying to power just my car stereo with a 750 watt psu but when i turn things on the fan spins once then stops and the stereo lights up then turns off.getting frustrated -.-

[@automachinehead]

@@blueballs8599 check the amperage of the amp. if it's 30x2 you need a 60amp or more psu

[@kyleyates8172]

Would it be worth adding around 5 farad worth of caps just to help keep the draw more constant when using a 12v supply to help increase the life of the power supply? I'm not using it for car audio indoors but I do need a 12v DC supply to run a few amps and figured the caps in series would help the power supply last longer and allow the subs and tactile transducers to have a better supply of power when they need it

[@Latrin600]

This ”music” in the background is awsome....

[@dustypotter926]

If you have a small amp say under 200 watts total you can use a Xbox power supply. If I remember it's output is 12.5 volts up to 17amps. You can get them online for like 20 bucks. I use one in my garage for the stereo out there works good for low wattage setups.

[@SparkedEd]

Exactly. Ive seen old power bricks at the thrift store for $2

[@bhagwansinghrana8224]

Which smps will be best between 12v 50amp & 12v 100amp to power my pioneer gm-d9601 class-d mono car amplifier ? The car amplifier has three fuses each of 40amp.

[@Josh-km9vc]

Also a DIY wiring diagram for dummies would be cool to have for reference.

[@bee-onabudget]

good video, thanks for the explanations

[@LEGOCAMARO]

Cant i just use a 12v battery with a battery charger on it to keep it topped off? or did i miss something?

[@sleepzzz800]

Would this be worth doing? Or would it be better to just buy speakers that are ready to plug into an outlet?

[@lyndonramchatesingh105]

Hey showtimeSPL can you tell me if a 50amp power supply by nippon america will power a 4 channel 2000w soundstream or 1500w 4 channel orion cobalt will that power supply dip or cause the music to buck

[@Josh-ify]

If you wanted to do a low-power option but wanted to be able to tote it with you, how would you recommend powering it? I've got an unused head unit and some decent 45W (RMS) 6x9's and am trying to power it in a semi-portable fashion for tailgating

[@user-tw4jk7fz7m]

I had a question....so I have a large RV that I did a whole custom theater with surround sound. Since the RV also has 12v battery's can I incorporate this into my theater/stereo. .... Does that make sense....basically I want to add some insane pro audio mid bass drivers and need a strong cheaper amp to push them....thank you

[@consuelos7836]

Very helpful!!!

[@edud8452]

I'm having flashbacks of my teenage years running two punch 12s off of a technics analog home receiver 😎

[@incorporeal3793]

Can I use a 12v 40A PSU for security cameras into a dc to dc 1200W converter outputting 13.8 volts @ 15A CC to directly power an amp and not damage it? And if so do I need to set the CC to just above what Ohms law says the Amps will be for a given wattage or is running it at 15 ok?

[@Josh-km9vc]

Can I use a Motiv Power Brick Power Supply (12V/60A/720W) that I found. Same concept?

[@farhanfarooqi7190]

I got bunch of old punch DSM amps I want to bench test. Is it ok to use a car battery but run a small fuse like a 5-10 amp to limit the current just to see if they turn on and work? And also use a radio as well to play music to make sure they have output. I was told to get an adjustable power supply but just wondering if it's ok to just use a battery? Also was told if these old DSM amps have been sitting for years and years just limit the current to like 3-5 amp on power supply but use a 5-10 on a battery.

[@bladerunner5788]

but i want to connect directly without battery and headunit is there a amp i can buy that works with car subwoofers

[@gopyyanusdev3486]

I have a transformer at the top it write 125 watt light it can turn it on and it 12v ac output can I use it to charge my car battery 🔋

[@Oguz_Salgur]

My amp is 1600W but i will only connect a 600w sub and my amp need 35 amps to run but you said i should times the amps of the power supply by 10 to get the Watts but i could only find a 30 amp power supply which is 300 W which i this in not enough for the amp and the sub to run so do i need a 60 amp power supply or something else?

[@jrizlechavez94]

instead of a car stereo as an audio source can i make it just an aux cable ?

[@roofpizza1250]

Is there any problem putting a car equalizer inline on a home system? Was thinking of my unused Alpine 3402 parametric to help with some sub bass.

Could i skip the battery and just use like you said a 60 amp power supply!!

[@Pittsburgh-412]

I have 3 Xbox 360 power bricks powering a punch 500. The rca's are running through my home stereo receiver pre outs. I do have a hybrid capacitor connected that displays voltage. It rocks the house for sure

[@AlbertoHernandez-tq3wm]

Could you use a 60w catalyst line 6 amplifier and also show a way to use a cast audio amp. Why? Because i want to bypass the audio limiter so that i can add other speakers to it what i have is two 12” and three 10” series or parallel what kind of amp do i have is 2500 mono block amp

[@chrisyerp174]

great tutorial video on how to .. I was gonna build this in my house several years back without the caps and battery supply thow . was looking to achieve around 1000 amps of power but all the power supplys where in the 3000usd range.. I might have to dig into it again with a super cap addition to it. maby it will lower the price on power supply so I won't need a such an expensive supply.

if a car battery puts out just over 12v and alternators supply a charge over that to around 13v give or take normally, couldn't you just run off a pc power supply using a 12v yellow and 3.3v orange wire together? or a dc power brick at around 13v, without the need for battery's and caps??

Any recommendations on a battery. I'm using a PM3-100LK converter/charger and have about 2000W RMS of power.

[@raiden72]

I ran my 3000w woofer with the XSPower D3400 in my car it worked super well honestly. Hey, for your PM3-100LK, that should charge AGM batteries just fine right? Looks like 100A*12v is equal to 1200w RMS actually, and your 15amp wall outlets only put out 1800w at maximum (15a*120V=1800w), so I believe the 2000W RMS figure may be exaggerated? or is that your Amplifier that is 2000W RMS?

[@karelessoriginals757]

follow the instructions in the video but for a rough estimate of finding watts multiply the amps by ten to get wattage

[@unixd0rk]

I'm finding that I'm getting a bunch of "local talk radio:" interference when trying to power my amp using switching power supplies, either PC or "brick" type. it's possible it's something else plugged into that circuit, i suppose. I'm still experimenting to figure it out, but running off of a standalone battery is dead silent. I'm definitely interested in that supply/charger you have but I can imagine shelling out $ and then hearing the same conservative talk radio interference and getting quite annoyed. :) I have some APC UPS boxes that need some TLC/repairs that I'm going to try out to see if those isolate anything.

I have 4 car audio/home setups in my house. I use 30 amp power supplies from Amazon that cost literally $20 shipped. For one of my systems I am using 3 separate 30 amp power supplies. Why only 30 amp power supplies, because $20. I actually prefer the sound of car amplifiers over home theater amplifiers, why? Power, clarity, and ease of use is why I like them. I can change out an amp say on my front stage speakers or my center channel, or the rears... I find it is more fun and stratifying setting up my own sound. I use the optical output from my TV to a DAC that converts to 2 channel analogue (RCA). Perhaps I will one day make a video of my set up and post it on KZbin....

[@sleepzzz800]

Whether it’s an AGM or Lithium battery, can I leave a charger on the battery as Im using the amplifier/head unit ???

[@raiden72]

I would say yes because battery charger cuts on when the battery voltage drops and then completes its charge cycle. There should be nothing wrong with using the amp as the battery charges.... your car does this same thing with the alternator charging the battery as you listen to your car stereo.

Possible what matters is the Amperes the power supply can deliver,500w amplifier needs 60A and above to constantly run the amplifier..am using Server psu and it's fine

[@mikestavisky8009]

Yup. Remember to piggy back (bridge) from the batt+ to the remote spot. Or tie a light switch (or any switch) with that bridge and you'll have an on off switch separate from the power supply.
