When you see a 1 farad capacitor that says for systems up to 1,000 watts does that mean just the amp and the subs or everything that puts out wattage like cd player, amp, speakers, and subs? Also how would you install a capacitor where there are 2 mono block amps in the car?
the 1000 watts the capacitor says means for example, you can hook 1 1000 watt amp to it, or any combination of amps that push 1000 watts together. the cd player isn't hooked to the cap, so it doesn't count towards the 1000 watts. and speakers and subs don't put out wattage, they use wattage.
you can just hook two wires off of the cap, one to each amp.
hope this helps. i'm sure you'll get other replies too.
