I'm Planning on adding three amplifiers to my Limited, I have the MTX QE-5 or whatever that thing is and also I have the wiring for the amplifiers too. All i need to do is find a factory service book and how to dismantle the trim to get into the head unit. I have three sets of 6 1/2 " component sets to go on the doors and in the back where the speakers set behind the passengers heads.
