Got a chance to get back to working on it, did a rough hook up to test things out. I'm so glad I went with the 8BB, and so glad that I could not the PMX2 to fit. Big differnces with how the bluetooth works with my iPhone, it shows album art with everything I throw at it, internal I phone music, google play, pandora - etc, where the PMX2 did not unless it was hooked up via USB. Also Bluetooth connects quickly, works better than my truck with a Pioneer head unit.
Very Pleased so far and getting great sound from that unit, still at flat setting and amp set to full range. I don't have my sub yet and haven't played with any settings yet.
