Going from 4 guage to 0

so 4 = 0 ?

I believe 2 runs of 4 gauge and 1 run of 8 gauge handles the same amount of current as 0 gauge.

If you're actually running ~1200 watts or more run 0 gauge all the way from the battery to a distro in back. Then run the biggest wire the amps will accept from the distro to the amps. Do the big 3 in 0 gauge as well. But as others have said 4 gauge is more than enough for the stuff you currently have.

pretty sure those ratings are max, not RMS.

I was actually using the ~1200 watts as a general rule of thumb. I'd imagine the Digital Audio amps aren't pushing anywhere near that.

Sorry, I was referring to the OP in my previous post.
