Nice instal work. Crappy sub - defenetly not one of the best in the market - not even in the top 10. Cheap JL electronics. No spare tire - but at least he will have some music to listen to then he is waiting for a tow truck. As far as MOST stuff having to stay intact - bolony - I own finished E55(although not the MOST) and S65(MOST) which is still in the build stage but works fine with our mods- no problem to replace equipment or go fully aftermarket. You could do aftemarket input with DensenLink and some other ways.
Again quality of an install is very nice - good fabricators, but I still can't see the logic behind loosing spare tire. Thouse things do blow at the worst times.
