I just got a 2003 mustang GT, i know it has a mach stereo system in it, im pretty sure its the mach 460 with the 6 cd changer, but im not sure. does anyone know the speaker/amp ratings off hand? and i was looking at putting 2 10's in from my old car (i know the deck doesnt support them w/o the conversion), but i wanted to save some trunk space, anyone know of a good place to get car specific boxes?
