Im about to re-do my system in my 97' Caddy deville. im taking out my two(2) type r 12's and putting them in my wifes car. its already wired for it since it was in her car to start. Can anyone give me some advice on this, i want to put six(6) type r 15's in my caddy. does anyone know if they will actually fit? does it have to be a custom built box? what size caps should i use? My caddy already has 0 guage wire running in it for pwr and grnd. I'll be running three (3) Hifonics gen XX colossus amps. should i also get another battery and alternator? already have an optima for the car.
