I've been having some audio problems in my truck. It has Kenwood head unit with 4 stock speakers. for my birthday I got some pioneer 4x6 and 5.25 speakers to install. Since I've owned the truck the door speakers never worked and I have a feeling something went wrong when the PO installed the head unit but I never looked into it yet. Now my questions....the tweeter under dash speakers that came in XJs, do our trucks have the wiring for them or do I have to wire it myself? also to change the rear speakers, do I have to take the whole b pillar panel off or can I just pop the grill off? It seems like the grill will pop off but I don't want to crack it.
