How to power car subwoofers in home?

Ive actually done this before.. Just get a 12 volt DC transformer. If you dont know what this is, it is that black box that you plug into the wall that alot of devices use, such as a home telephone. This will convert the 110 ac from your house to 12v dc, which is the same as your car battery. Just hook the positive and negative to the amp, and then also run the positive to the remote antenna location on the amp, which will make it turn on.

I have a set up on my garage all you need a power inverter you plug this in to the wall and convert house power supply to 12 volts which is what you need to power the amp you can get this on any auto parts i hope this help:)

The computer power supply will not be able to keep up with that amp. Use a home audio amp or d.j. amp, it will be a lot easier and probably cheaper in the end.

You will need to get a switching power supply from radio shack. I got and you wire it up to your amp. It converts your a/c household current to dc current for use on the amp.

A computer PSU doesn't have near the amperage capable to run such a system. At most a PC-PSU can deliver about 17 Amperes. A car amplifier that pushes 760 watts RMS (380 x 2) will require at least 40 amperes. This will cost over $200 just for the supply. http://www.powerstream.com/low-noise-high-power.htm _________________________ Unrelated but important.... The thing is, people get confused in the real purpose of a cap. It is not used to cure or prevent dimming lights nor will it change the way the system sounds (both are misconceptions). To undertsand the purpose you need to understand how they work. A cap does it's best to keep the voltage at a certain level, but if the voltage changes so will the cap voltage. The cap just makes the change smoother. The diming light syndrome isn't a voltage issue but rather a current (amperage) drop. The voltage simply follows what the current does. A cap does not help this situation at all. A cap doesn't provide more power nor does it try to correct it. A cap is perfect for a noisy voltage line or if the car has fast, erratic voltage spikes/drops. This is why caps are used in AC to DC power supplies as they are used to smooth out the DC ripple for a more smooth DC output. The ONLY cure for dimming lights is a more hefty amperage source, the alternator. The REAL powerplant of the car is the alternator. The ONLY purpose of the battery is to start the car and run the accessories with the engine off, nothing else.
