Anyone out there use a capacitator with their car stereo systems? I'm about to get a 12" Sony Xplod sub and 800watt Kenwood amp installed in my 97 Jetta GLX, so I was just curious if anyone had any advice. Also, did the car performance suffer as a result of the amps use of the electrical system? The last thing I wanna do is jeopardize my cars power and performance, so any help would be greatly appreciated. Thanks!!
