Car Amplifier and Subwoofer Powered By a Computer Power Supply
Headphone Hybrid Tube Amp (SSMH)
Yo, still trending these days, i really want to know i only got 6 yellow wires and like twice the quantity in black wires, should i do all black with. 6 yellows? Or 6 yellows and 6 blacks?!
Please help me out which wires to put in the +12v power supply
yes, You better have a corsair 1200i to power that u may need even more power. Depends on how much current ur app need. just look at the fuses. if u have 30A fuses then u need a PSU of 360W or more (12V x 30A = 360W), so if you have 2 of those amps you need 720W or more PSU. simple math, Ritght?
oh yehhh that PSU is wayyyyy to little power
Hi all, i'd like to use 2 PSU's to power one car amp. Any technical issues to look out for ? Will it work efficiently with no problems ?
Hey. Iv used this method to power my amp and sub with a psu that has a max wattage if 400. It eventually died as it was old and sqwealed from the start. I have now got another psu with a max wattage off 285. The amp lights up and the psu powers up but there is no sound from the speakers!!!!I only used a singal wire this time, is this the problem or is the psu too low wattage ?
Hi all. I would like to build a project like this that's full range. Maybe a pair of 5" coax and an 8" mid-woofer. I assume I could still do this using a 4-ch amp with two wired together for the sub? If I did something like 4x50 watts at 4ohms, could I get by with a 30-40A psu?
Why does my power supply shut off after a couple of seconds after plug in. Only when hooked up to amp? No speakers or rca hooked up yet.

Looks like a mess. Sound like gods! thanks for great instructable! :)
Overall, you've got most of the basics down regarding getting this to work, but I think you need to learn some fundamental electronics. Especially in regard to basic concepts. (Hey, I was new to this not that long ago, so I can sympathize.) Voltage does not "flow". Current flows. A device does not "put out" a certain amount of ohms. The ohm rating is simply the impedance (resistance) of a particular circuit. You can't say things like "your amplifier will require a 4ohm signal". That's not how it works. Sorry, not trying to be overly pedantic, but a lot of this information is misleading or just wrong. Still, I guess it gets you over the finish line, which is the point.
atleast with 25amp at 12v
I got a 250 watt house subwoofer with built in amp i want to put in my car wat size power converter would i need and would it mess anything up - Fragantbump
Im using a x box 360 power supply its 175 w max 12v 14.2amp to power boss 1100 w monoblock amp pushes a polk audio 12 in sealed enclosure its been 6 months i stress tested it using it fairly high daily no over heating or issues at this time - Ma2016
Stress tested for 6 months it shakes my apartment after 3 hours of loud music its barely warm i love it added bluetooth for easy music playing love it. - Ma2016
1200w single rail will provide 100amp,should be enough
QUESTION: reference the back of your receiver. Okay, I'm having a hard time to word this, BUT, okay, so the back of your receiver I see where you plugged in your speaker wire for the amplifier. Do you also have speaker wire coming from those same terminals to goto a normal speaker aswell? That's what it looks like, I wish the angle was a little bit more clear. You see I also run normal speakers off those terminals. Do you understand my questions? - ChrisR161
Im buying a 1000 watt amp how big of a psu do I need? - DaytonD
A car battery typically puts out 500 to 600 amps. Read your battery look for its CCA (Cold cranking amps ) Amp power wires are so big because the distance from the battery to your amp, would overheat a smaller wire due to the resistance of the wire and the load ( your amp) being at a distance. The smaller length wires on a psu work because the distance has fews ohms of impendence.
Watts divided volts = amps. A 1000 watt amp divided by 12 volts = 83.33 amps.
The formula for figuring out how many amps....and therefore the size rating of your cps is this... watts divided by volts = amps. A 1000 watt amplifier for example....1000 divided by 12 volts = 83.33 amps.
I beg to differ with you. Car stereo equipment can surpass the sonic clarity of home systems...lower total harmonic distortion. And a 100 amp cps is enouh to power a 1000 watt amp. Watts/ volts= amps. So a 1000 watt amp needs 83..33 amps of power.
The length of the power wire used in a car is different
question, is there any other way to ground my AUX wire? when i plug it in from my PC it powers off, when i plug it into my phone, it works awesome, im using PYLE PLMPA35http://www.amazon.com/Pyle-PLMPA35-2-Channel-300-Watt-Amplifier/dp/B004HJ931M
Just sell your car stuff already and by some respectable home av gear. Car audio stuff is dirty noisy has poor sonic accuracy and this is a super inefficient way to makes some noise. Multiple switching supplies, lots of drops, lot's of heat, and you would need a 1000 watt psu to get enough current at 12v to be useful to properly run a modest 100watt 2 channel amp.
