School me on busbars

[SS4Luck]

So I understand what they do but not exactly how to hook everything up to them.

Im going to be running two D3100s in a tray on the back floor of my truck. They have to be end to end because of how my box hangs over the rear shelf that Dodge put in so Im thinking the easiest way will be to bar 'em.

Im going to be running 4 1/0 runs in and 2 1/0 initial runs then after I get everything running smoothly and have more $$ im going to have toolmaker dual inputs on my amp to help it keep clean so eventually it will be 4 out runs.

Is there any certain way to hook the bars up? Can feed runs be next to out runs? so its like (think in holes/connections) battery in in out out out out in in battery

Also for a hair over 5000W what material and size would you make them out of?

As long as the bar is positive to positive and negative to negative on your batteries it doesn't matter where you put things on the bar. When you think of a bus bar think of it as "growing" a single battery to have more capacity. It's okay to have wires from the front battery/alternator near or on the same stud as the wires to the amplifiers.

As for material it really depends on your budget but I'd suggest aluminum, or if you want to spend a little more go for copper.

A buss bar is used as a wire. Just doesn't have a rubber jacket on it.

I would use copper, you can go smaller in size if you use pure copper, I would do 1/4 inch thick by 1.5 inch wide copper. You can get a 6ft stick of that online for around $100. And you want to link all the positives on positive side, and all negatives on negative side. And I suggest doing input and output for your wire connections to the bars. Alt input positive at one end and alt input ground at other end, then chassis ground/amp ground at other negative end, amp power at other bar positive end. Kind of hard to follow. Ask questions if you got lost, lol, but input/output is how the bars should be wired.

Where? I couldn't find anything that cheap. The cheapest I found for 2 8in bars 1/4 thick and 1 1/4 wide was $80. Average at local shops was $150 with the highest quote at $210.

Copper bars

8964K85 on that page, $103.45 plus shipping which is like $10. That is the exact bar I used to link my 5 batcap 4000s, cut it in half, 3ft on positive end and 3 ft on negative end.

That is so upsetting. I paid $40 for these and yours look so much nicer.
