I am buying a system that consists of Three 12" Menace Audio MA-122 Subs, Ground Shaker Box and Kole 2200 watt amp. I am putting this system in my 1992 Buick Park Avenue. The battery is a cheapo autozone duralast and the alternator is stock. What would be better, Running a second battery in the trunk to the amp or running a capacitor off of the battery to the amp?
