instead of 1/0 wire can i do a Big 3 upgrade with 4 gauge wire?
A shopper on Jun 7, 2015
Best Answer: this wire is 4 gauge cca. not good for big 3 at all but helps 50/50 i would recommend that if you do your big 3 to use ofc 4 gauge from knukonceptz or skyhigh. i was supposed to get that first. but in 0 gauge.. how many watts rms are you running ?

How long is the power cable ?In meters ?
I have the battery in front and my amp back.

Best Answer: Sorry I answered for the wrong wire. I recently bought 2 kits. This kit is for a big 3 terminal upgrade on your battery. This cables only run 1 to 2 feet in length and are only meant to be used under your hood from the alternator to the battery and ground. THIS IS NOT AN AMP KIT!! Again, you are over your head, take it to the pros.
