Ok my car keeps turing off when i have my system on with other electronics. the lights dim extremely then the cars RPMs just drop and nothing electrical works. i have a 1000.1 kicker amp. i also have a capacator. i need some advice. would i be able to put a spare battery in place of the capacitor or should i just upgrade my alternator. i have a 70 or 80 amp alternator now im not 100% sure but it 1 of those. if i should upgrade my alternator what amps would you recommend.
I need to know asap thanks.
