I have a couple questions if anyone can help. #1 Would a bad ground connection still run the amp? #2 I originally had a 6 gage wire for the ground, I must have trashed it while removing the system from my truck, all I had laying around was a 8 gage, how much of a difference would that make? Basically what is happening is there is power going to the amp and its pushing the sub but only if I switch on the bass boost and mess with the bass level. I know for sure everything else is installed correctly thats why i think it might be the ground wire. #3 last question i promise, wheres the best place to ground? Thanks for any help.
