I am running the front comps off a bridged jl 300/4. Any time I turn the volume up past 0 I get a really bad hiss through the speaks, even with the engine off. I have the HU grounded to the chassis by the HU and the amp grounded at a seatbelt bolt in the rear. The power and signal wires are run down opposite sides of the truck, but one speaker wire does run over the 0/1ga power wire right behind the firewall, but I crossed them at 90degrees. I think it may be a ground loop and was going to try regrounding the HU at the same spot as the amps on the rear seatbelt. Does this sound correct?</p></blockquote><p></p>
