  • Car Amplifier and Subwoofer Powered By a Computer Power Supply

    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.
