Anyone? It took a look and it appears that the front door speakers are 6.5" but I couldn't quite tell what size the rear speakers were. Also, what kind of luck has anyone had with putting in a pair of 12" subs into the trunk? Good fit with enough airspace? Any feedback would be greatly appreciated.
