Would doing the "Big 3" installation be pointless for me?

[ckunke002 10+ year member]

I'm at about 700 watts with just my car audio gear, along with however many watts my cars stock electronics are using. I was just wondering if I would see any gains from upgrading my big 3 wire connections to 0 gauge wire, or if it wouldn't show any benefit until I have a 1000+ watt system.

Any feedback or info is much appreciated. Thanks!

It will help any electrical system by upgrading the grounds. You may not hear any difference but your car will thank you for it.

If you are planning on upgrading go ahead and do it in 1/0 guage, in actuallity if your pulling 700 true watts to the audio system alone, turning your headlights on with the air condition and a mass of other electronics, its very reasonable to assume you will get some voltage flux on a stock electrical system...so if nothing else I would go ahead and do a 4 guage upgrade
