Posted February 8, 201015 yr I'm about to order a 25ft. roll of 1/0 gauge wire to do the Big 3. I watched the video from Maxxsonics on it too see exactly what I needed to do, and it shows him pointing out 2 separate grounds that were stock on the vehicle before he added any wire. One from the battery to the chassis, and one from the engine block to chassis. When I opened the hood on my Altima I saw that there was only one wire coming off of the negative terminal on the battery, it grounded straight to the engine block. Is this a sufficient ground, or do I still need to find another bolt somewhere on the block to make a new connection to the chassis?
February 8, 201015 yr Leave those wires alone. Just add new ones. Neg batt to chass and chassis to engine block. Block ground is fine. Are you not doing the pos wire?

Are you not doing the pos wire?Yeah I'm doing the pos wire too. I figured that part out, my main concern was that there is only one ground coming off my battery, the neg term to engine block. That's why I was asking if I should just replace the stock neg-block wire, or should I replace that and also add a new block to chassis ground, cause as far as I can tell there is none. Thanks for the quick reply.
February 8, 201015 yr Again, I would leave all stock wires alone. Just add the new ones even if you have to make a new grounding point.

I'll let you guys know how it turns out. Any idea what size fuse I should run in between the alt/batt? I'm running 1000w RMS and I don't plan on exceeding that.

I dont fuse there so Im not familiar with how large you should use.
February 8, 201015 yr most ppl don't fuse that wire b/c they like to live on the wild side/dangerous side! i fused mine at 250amps though!rememember you are supporting a 1000rms setup in the rear in the front fuse to the wiring limit to get maximium amount of current! but in the rear if there is no fusing on the amp make sure to fuse it at the distributors recommendation!but from battery to amp (front to back of the car) make sure to fuse that wire also unless you are running multiple batteries
