Short Run Of Ground Or From Front Bat To Rear Bat?

[RnK1026]

im runnin a 200 amp alt with the big 3, 0 gauge all around to a kinetik 2400. system consists of one old school US amps2000X and 4 L7 15s in a 14 cubed ported box. i am seeing massive voltage drops right now and i realize i should probably invest in another 2400 but in the meantime, i spoke with cliff at ohio generator and he explained how i should get rid of the big 3 and use a run of 0 gauge from the front bat to the rear, then ground the rear battery. my grounds are currently seperate and he explained that i want ALL of my electrical TO THE SAME GROUND. ive always thought just to run the smallest run of ground in the rear to the frame. can anyone give there input of this whole deal? its much appreciated all-----Rob

your front battery is grounded at the frame anyways so if you do the same to the back batts they will be in series and it is perfectly fine.

Run a ground from the front batt the the back batt then a short ground from the back batt to the body or frame

It would be helpful to know what kind of a vehicle you have. It sounds like you have a truck with a frame under the body - if that is the case, the frame rail will have lower resistance than any cable you could run along side it. Also, define "voltage drop" . . .
