Battery & Wiring Question

[jagblazer01]

So im upgrading the stereo again and I will be running 4 2400s in the rear of my truck. I have 2 runs of 1/0 going back there now and dont really want to do 2 more runs. Will I be ok with just 2 runs back or should I do 2 more?

Second part of question lol....I have an 1800 under the hood. Should I isolate the rear batteries or no? If so, would I use 2 isolators (1 for each 1/0 run) or just run both hot wires to 1 isolator?

Or if anyone can point me in a better direction that would be a plus as well.

what kind of amps are being hooked up? more runs creates a higher voltage in the rear due to less resistance, and is probably a good idea if you're trying to do competition of any sort. What do you have as far as alternators?

IMHO isolators are useless, just dont bump with the engine off for too long and you should be fine

jag im running a 300A EA alt in my truck with 3 runs of 1/0 to the back. i noticed a huge diff going from 2 runs to 3 runs at my back batteries without isolaters.

really??? then I may be considering running another run back there......did you run yours under the truck?

Two runs will work fine. Make sure you ground all you batts, alts, and amps to the same side framerail, (not the sheet metal body) and DO NOT use an isolator.
