4 AWG substitute for 1/0 AWG???

I know this isn't ideal but I'm hooking up a buddies system and he has two amps one is 400 the other is 700 watts RMS and they are both class A/B. I know it would be best to run 1/0 gauge from the battery and distribute it at the trunk, but he doesn't want to buy the 1/0 kit when he has a whole spool of 4 AWG...so here is my thought...4 AWG can run high ampere for short runs, so could I run about 6 ft of 4 under the hood and through the firewall, them quickly distribute it into 2 runs of 4 that will run to each amp....there would be a fuse near the battery on the singe 4 run for 200 amps... I thought about doing something like this for myself but ended up doing it differently...would this work?

4 awg will be just fine for that power if its good wire...

its kicker PK series with that hyper flex technology or whatever

And do you mean running a single run of 4 AWG?

Hyperflex is awesome wire... Just run a single run to the back or where ever then to the distro...

Think so...I mean each of those amps have 75 amperes worth of fuses...making that wire need to handle 150 amperes

That wire is rated up to 150amps so you should be good. P.S tell your friend he is in the wrong hobby if he hates spending money.

Haha thanks man, I agree....and he has the money I don't think he minds spending it all that much we seriously have this big *** 100 ft spool of 4 AWG that only like 15 ft got used from, so its prolly more like a "lets actually use the stuff we payed for"

Sell it and buy something that can handle any future power upgrades. Saving a buck today can end up costing you $20 bucks tomorrow. Just a thought.

P.S if he is interested in selling say 10ft of that 4awg PM me. Wanna upgrade my 8awg on my 9.2.

4 gauge will work.

I agree, if you don't want to spend money, get out of this hobby now before it sucks you in.
