Did you eliminate the factory AMP? The PO on mine also changed the speakers to entry level Pioneer and Alpine in the rear and they were horrible. But it could be the head unit too.Nice. How does it sound? I’m literally tearing all of the old trash speakers out of mine. Will most likely go with the Pioneer 8400nex since you get both DVD and GPS with it. Haven’t decided on speakers yet.
I have done many a Stereo swaps and honestly I am just stuck with where I am going with this one.
I also found whole hog tech on here who at least used to make a mount for a sub in the rear for us LX guys. I reached out to them today to see if they still have some. It would mount in the factory location and hold an AMP. Just add a grill cover.
