the alpine stuff is a little overpriced in my opinion. good quality, but for the features in the processor, i think there are better options. the processor needs to go to an amplifier though, so if you intend to use it, you will need one. i have not installed one because i tend to prefer the alpine radios only. but reading the specs on it, it doesnt allow you the tuning options as a mosconi, audio control, or hertz/audison. the speakes will be fine, but you will need some modification to get the speakers in the doors. for a sub, i will be putting audiomobile gts10's in mine. they wont fit a supercab, but they do fit the crewcabs. i actually like them better than the jl tw3.
