i got a set of kicker l7 12's 750rms each @ 2ohm & im planning on getting a 1700 watt amp that will run at 1200watts(just to be safe so i dont blow my kickers) anyways i already have a bose sound system w/subwoofers i think 8" & an amp(not sure how many watts bcuz its inclosed where i cant see) can i add a 1700 watt amp without getting a new alternator? Or do i need a higher amp alternator? The cars a 01' cadillac catera. Help please!
