I have an 04 with the Mach sound system, the right front speaker isnt sounding right anymore so i want to upgrade! Can i get some advice on a good way to upgrade the whole system? should I keep the Mach amps and just get new and better speakers all around? does anyone know if there are any door speakers that wont fit in stangs becasue of depth, or should they all fit? I want to be able to really crank up the volume! what did you do to your stangs sound systems??

You could always check out someplace like Crutchfield... they have a lot of good information there about what will and what won't work.
