ok i have a 4 gauge power wire running already and a 500 watt 2 channel amp for a already used system i want to add in a 1 channel 800 watt amp for new subs and use the old 500 2 channel amp for the rear speakers and i have a capacitor how do i wire all of this together and ive neva wired a cap b4 so i have no idea how to do that
you need a Power Distributor for easier installation. You should get one Power dist. with 0-4 gauge INPUT and 2 or more 4-8 gauge OUTPUT. Capacitor usually have 2 possitive and 2 Negative terminal. Connect your Power line to one pos. terminal of your Cap and another Pos. to Power Distributor INPUT. Ofcourse Ground your Cap to the body of your car and leave 1 negative terminal empty (DO NOT Ground Capacitor with AMP). Now you have 2 or more Power output from your Power Distributor, just connect your amp. normally.... Note, since you will run both of these amps on the capacitor, you should have 1.2+ farad (recommend 2+ farad, since every 1 farad for 1000w).
