What source gives most amps on 12v?

I want to move my car subwoofer home.. I tried to power my amplifier by pc power supply on 12v but every 2nd or 3rd bass i lose power.. I need 30+ amps on a 12v source..


Battery, no contest. Even a small 12V 7AH battery driven from your PC power supply or a charger should work okay in your application. You will have to replace it every year or few when used this way, but it is still your best bet. The source has a large selection but these batteries are everywhere.
