2 Amps - what gauge main power?

[Istari1 10+ year member]

Ok, its the usual question I am sure. I have a Zapco 360.2 and now I just picked up a JBL BP300.1 for a sub amp. Right now the Zapco is running off a 4 gauge power wire. Do you think I can still use that 4 gauge and split it into two 8 gauge power wires for these amps? Or am I going to have to run an all new 0 guage power wire? Obviously the 0 guage would be the BEST solution. But running an entirely new 0 gauge is going to be a big PITA and will probably mean the sub doesnt go in for many months, but I also dont like to cut corners.

Running under 1000w total RMS you should be fine splitting the existing 4awg into 8awg feeding the amps. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i wouldn't split it into 2 8 guages. split with 4 guage until you run a 0 guage.

You can do 4awg for main power. Best choice would be 1/0 main split into two 4awg. If cost is issue, get weldingsupply 1/0..cheapest you'll find then get a distro and a new fuseholder/fuse

If the runs are short enough why not? When considering both amps are

Obviously. That wasn't in question.

I inquired as to why you would choose not to do so in an attempt to possibly educate myself (seeing as that is ostensibly the main purpose of this discussion board). It wasn't in an attempt to flame but rather to learn something.

i would run 4 because i don't like 8 guage running power to anything.

Fair enough. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Lol, well thanks for the replies so far. . . not sure if I have an answer or not //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

if none of those work for you, you could split the 4ga power to two 4ga (one for each amp)

run parallel 4 awg. pretty much (2) 4 awg wires total (1) to each amp should be plenty fine with your setup

You'll be fine with the 4 AWG from the battery and 8 gauge from the dist block. I don't see any reason to go with 1/0 gauge considering the power you are running.

one 4 in and two 4s out?
