I live in springfield
I have an Alpine 9807 (I think? Its been a year) head unit also, and an adaptor for it for the mustang. But I feel wary about getting rid of the stock system

. However, if I were to put that in, would I then be free to put in what speakers I want? I also understand there will problem be an amp problem...
I also have a 450 watt lighting audio amp I got for $50 new, and a nice amp wiring kit. But this car seems to be too complicated, so I never got around to doing anything on the audio
