ok im new at all this stuff...but heres my situation i just bought 2 12" Audiobahn 800w (400wRMS)special edition subs, and a sony xplod 1000w class D AMP. I have the subs bridged in the box but not at the amp. Do i need a capacitor, or need 2 do any alternator mods or anything like that?? When the bass is at peak and vehicle is running the batery meter goes from resting at 14 down to about 11 when the bass hits and the headlights dim and all lights on inside of truck dim. I have a 2001 s-10 extreme if that makes a difference. but thanks for your time and please help!!!
