Wire question.

I have a question, my 20.1's and 6.4 amps should draw around 500-550 amps at full tilt. This being said, do I need two runs of 1/0 since it's rated at 300 amps to keep up with my amps? And if so do I need two runs on all of my battery connections from alt to batt and batt to batt?

I believe that rating is for a 50 foot run. There's a chart somewhere on the internet if you just wanna google that.

If you think you're actually going to draw that kind of current regularly, you'll want more than just 2 runs. Additionally you'd need dual or triple alternators and many batteries.

I dont think your goingt o be pulling that much power...

i don't either by a long shot.

When you add an extra battery you don't increase the alternator output..so it's just a temporary back up right?

Kindof but not much...its more drain on that alt

No but you give it a buffer to handle peaks.

Really? Care to explain that? Don't waste your time, you can't do it but it isn't true unless the alt simply can't keep up with the AVERAGE current draw of the system.

That is what nick told me 500-550 amps

I am going to be using 2 xa d2400's and 2-4 d680's plus a ho alt for sure.

Ohms law....wattage/voltage=current or P/E=I
