well i would definately run the ground cable to the seat belt bolt. i would run the main power wire either thru the firewall on the passenger side where the antenna grommet is or on the driver side thru the firewall. but if you do it that way it would be alot more wire used. make sure wherever u put the ground that it is tight and clean of any paint. if you need any help i would definately ask smnw2003, he was a big help with my install and will talk u thru everything. thanks again smnw2003 the systems bumps and sounds awesome.85S10Eric said:Well, I think I'll be installing my whole system soon, amp and subs included. I need some help with the amp install, as I've never done such a thing. I'd like some specifics, like where to run the ground cable, etc. Thanks.
