did the big three and upgraded all wiring from front to back tin 1/0 gauge. and put a 2400 kinetik in trunk instead of the deka. amps still cut off around 9.9vlts whats the problem here? do i need a ground from front battery to rear, i have the rear grounded to chassis with 1/0. I have the power wire for the trunk battery coming directly off the alt fused with a 250amper. the front battery is also tied into the front alternator like it would be stock. I need to find a way to seperate the batteries on alternator because i think they are pulling off eachother.
2- Mtx 9500 12" dvc (wired to 2 ohm each)
2- mtx 81001 amps (1000 wts@ 2ohms each)
1- mtx 7804 amp (200x4)
1- 15 farad stinger cap
1- yellow top optima (under hood)
1- 2400 kinetik battery(trunk mount)
1- 200 amp H/O alt
1/0 wire through whole car
4- 6.5" mids mtx
2- tweeters and crossovers.
only other thing on my battery is the air ride compressor which pulls 7 amps at full pull but is only on every now and then not while amps are under load.
