nethole

I've seen a number of people who said they've grounded their sub on the front passenger seat area. I just tried to loosen the front left bolt, couldn't do it.
So please show me which bolt/connection did you use for a ground?

king nothing

I hope you're talking about grounding the sub amp, and not the sub itself. As far as the bolt goes it probably has threadlocker on in. 1/2" drive ratchet and a breaker back should get it lose. The seat boots in my old dodge were a bear to take out
