Under what circumstances do you need a capacitor?
My brother recently bought a 93 Merc 300 and wants to install his old box set in the trunk with a 300 watt amp I think and one other and and 2 10" speakers. We went to Best Buy and asked one of the car guys there about it and he said he would need a cap, and my brother wasn't sure if that was true.
Unless his headlights are dimming when the subwoofer is making noise, he doesn't
NEED a cap. however, they do wonders for your sound quality (The amp isn't working as hard because the voltage is right there, instead of being drawn from other things like headlights).
I'm going on this road with my car; 250x2 watt amp and a 12" subwoofer make my headlights dim in daylight mode only, but not when full voltage is supplied to the lights. So I think I'm gonna install one next month and see how well it does.
