Good Afternoon All, Can't seem to get any response from previous threads so I'm creating a new one to hope clear the air, because i know I'm not the only one researching this. I'm replacing the stock sub/amp in my 06 EB and I've already pulled everything out from the truck Now, the old sub is a dual voice coil. The new one is a single. My question is, would it be easier to just run line level wiring back to the head unit(like every other sub I've messed with) OR can i use the stock harness to keep from having to do this with the amp? If it is possible to use the factory harness to do this. Does anyone know where i can find a diagram of what the wires are in the harness? It seems to be something no body can find, or somebody is keeping to themselves. Any information is good information at this point. I would like to wrap this up and do a detailed write up on it. Thanks for looking!
