I bought two 12" subs and tried using a converter to get a set of Pre-amps. But of course it did not work. So does anyone have any suggestion on what stereo I should put in my car. I have a 2002 Ford Mustang with the Mach 460 system. I am not sure what stereo will work and if I need a wiring harness to make it all work. I really need your help guys. I have had my subs for nearly a month and have not got to use them yet.
