Hey guys,

I need a little assistance for my power wiring. Shown in the photo is what I think I should do from reading around the forum. I'm not 100% certain it's right, so I'd like your input. Please feel free to save the image, and fix any problems you see in it and post it, or pm it to me.... or you can simply reply to this thread. The only thing that's not pictured that will be added is 2 distro blocks, 1 for each amp.. to split the power into dual 4awg for each amp. All wire shown in image will be 2/0. Please let me know your suggestions.

Thanks,

Marcus

you only need 1 fuse per run of wire, more than that is overkill regardless of wire length. if the wire shorts or overloads, the single fuse will blow, there is no need for a second fuse

and make sure all your batts and amps ground to frame

 
i would run both batts togther neg to neg and pos to pos, and run ur powers from one batt to ur amps and chassie ground batt in rear and run another ground back up to the front batt, thats just me. the neg will find the least resistace in both neg runs for a better ground especialy if u have the big 3 done. just ground ur amps back to the neg on the batts ive always done it this way and never any ground noise or probs, i would say 4 to many fuse holders.

You are an idiot.

If you need the fuses there on the inputs and output of the batteries. If it shorts in the middle... (in between any of the batteries) and you only have one end fused... the fuse near the battery will blow... but if the other end near the next battery in parallel is not fused... then it will be a dead short from a live battery.

As for your diagram, it's almost correct.

Ground all your amplifiers directly to the battery. Connect the battery negatives together in the rear. Either run a negative run back up to the front for you ground... OR get a solid frame/chassis ground in the rear.
