What are you going to splice the amp in to, that will show it 12 volts? What battery is going to power the amp? Maybe a deep cell that just happens to be sitting around. What audio card is there, that will provide what a car amp needs? Just a few questions you might want to ask yourself. Why not just buy a good audio card and a highend computer subwoofer system. Not that I would try either, but I would try a home stereo system subwoofer before a car audio one.
3 different OS, so yep I\'m confused.
