[QUOTE="holbrodu, post: 4186035, member: 587847"] ok where to start. i just got done installing a second battery new power wiring and a new amp. i upped my wiring to all 1/0 gauge except for the new batterys ground which is 0. the battery is a deep cycle with 850 CCA. i put all this in because i just got a new amp. it is a audiobahn A2200HCT it pushes my 2 lanzars 12s at 1600 watts rms at 1 ohm 3200 watt max. it was a very painstaking upgrade because i ran into a bunch of little stuff (got it done in 12 hours). and after this greuling experience i started it all up for the first time and i have horrible engine noise coming through my 6x9s. i suspect a bad ground on the amp but im taking a break right now. i did all the wiring up right with nice ends i thought i did a quality job but i did something wrong. i have also never wroked with 2 batterys before this so do i ground my amps to the battery or the frame or does it matter? i also have a 5 farad cap between my second battery and my amps. see below for my headunit and etc. [/QUOTE]
