I have 1200.1 Kicker Amp = 1200 RMS 2400 Peak with Dual 12" Kicker Comp R subs that peak power at 3200 and RMS at 1600. I have a 1 Farad Capacitor. I also have Kicker KS68 6x8s in all 4 doors.
The best buy guy told me to upgrade my alternator, but other people have told me to put in another battery.
What do I do to keep my car from killing itself.
