rockFord_Expedition Posted April 11, 2014 Report Share Posted April 11, 2014 I think it depends on the vehicle. If you are talking about ADDING a front to back - run, no it wouldn't hurt a thing but if you are talking about doing that instead of a proper frame ground in the rear, I say you are better off without it. All depends on the vehicle I guess. Enough front to back runs can be just as good or better than a frame ground in the rear in some instances, but we are talking about a whole lot of wire.

Wheelz_pitch Posted April 12, 2014 Author Report Share Posted April 12, 2014 Well the run is already in there and its a 96 explorer. And the way I figured it is that power would travel with less resistance in a wire compaired to a frame. And as it was mentioned earlier I'm gonna swap the neg to a pos. And see the difference.

rockFord_Expedition Posted April 12, 2014 Report Share Posted April 12, 2014 I don't think you will hear a difference, but I will tell you that the frame provides less resistance than a single run of 1/0.

alaskanzx5 Posted April 12, 2014 Report Share Posted April 12, 2014 To many variables to say really. Depends on the car, setup, etc etc... do it and a good solid frame ground then test switching it to a pos run like said. Just see what works best. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
