Should be fine. I think the rule is never have a ground wire smaller than your power wire. Larger should be fine. But if your power wire can do 0 gauge then you should do 0 gauge on it as well. Would make sure the amp is getting enough power.I didnt do the ground properly because its not on bare metal. there is paint under it. I am going to do the big 3 , just wanted to know also is it ok if I ground the amp with 0 gauge and have 4 gauge power wire?
Also for your big 3...if you already dont have the wire...save yourself some cash and pay like $1.30 a foot.

Just got that myself. I dont think the wire is too flexible even though he says it is...BUT o well wire is wire.
