hello,i have lots of 8 gauge wire resting at my closet. And i'm very interested on doing the big 3 upgrade to my 2000 mitsubishi eclipse gt. May i see any improvement with 8 gauge wire?...i know that at least 4 gauge is recommended...but i dont want to spend money.
4 gauge? LOL Go big or go home. 1/0 gauge or it didn't happen.
first, do not remove any of your factory wiring. only add extra wiring. it would work if you did two or three runs of 8 gauge wire instead of a single run of 4 gauge wire.
Go cheap, get cheap. Improvement, maybe. But heres a secenario: current draw exceeds capacity of 8 gauge wire, insulation melts, positive wire grounds out, lots of smoke, fire.... no wait... FIRE! Oh s**t that's gonna cost me..... (a lot more than 4 gauge wire I'll bet...)
You probably won't see/hear a difference even if you use 1/0 wire, but there will be one. 8 awg big three will probably at least double the current carrying capacity of your stock wiring. To say it would be a waste of time would be ignorant IMO. It certainly won't hurt anything and will make a significant reduction in resistance compared to what's already there. I did my big 3 with 8 awg. I'm running 1500w rms with a stock 130A alternator.
