I'm building out the new Rockford Fosgate Stage 6 kit a little at a time, but with the PMX-8DH (and PMX-8BB) as the head unit. The new Stage 6 kit includes an updated dash kit that is compatible with the PMX-8DH, but they don't highlight that fact very well. The new kits are due to be released around April, based on an email reply to one of my questions. I chose the PMX-8DH as I wanted a larger screen for the backup camera. I have the original Stage 1 dash kit available, but have chosen to design and purchase a custom center dash from
ExtremePerformance1.
The new audio roof choices are nice, and certainly very simple to install. However, I will probably install an aftermarket cage eventually, and again, I wanted the larger screen than the PMX-2 or -3 offer. For some, there is a concern about adding that weight up high. For me, it's really just a concern about aftermarket cage compatibility and other preferences.
I'll stick with the under seat subs, "wake tower" and dash speakers.
