I tried the search but still did not get a deffinate answer out of it. Does the Xa/Xb come prewired for the bazooka tube, i.e. if you don't have the bazooka installed is the wireharness already there anyway just tucked in either one of the side panels or under the rear seat? If it is there, has anyone used it to serve as a signal source for an aftermarket amp? We will be using a MTX Thunder series amp which comes with speaker level inputs so there is some install flexability.

 

The wiring harness isn't there at all. I think it get's installed if you order the bazooka from the dealer. I installed an aftermarket amp and sub and had to splice into the rear speaker wires and use a line converter. It would have been much easier if the harness was there, but, alas, 'tis not!
