So overall, it wasn't too bad. I had to mount the crossovers IN the door! I couldn't find a place to mount them externally and still get the door panel on, so what I did was find a place to loceta them in between the panels in the door. Then I drilled couple holes and and a combination of dynamat, and screws and washers, securely mounted them out of site! I did make sure wiring and sound was correct.
I still have to mount the amp in the back, but am really considering adding teh sub and other amp now, while it is still somewhat open for adjustment. Anyways. The thing sounds fantastic. It sounds like I have a small 8 inch sub in there now, but putting 4 6.5 speakers in there, and extensive dynamat and sealing will do that, won't it?
