I just bought a 03 mustang gt, which is an upgrade from a 95 mustang v6. i was looking around some information about hooking up my old amp and 2 10" speakers to the mach 460 system and i saw the mach 1000. I really like the trunk room it allows. anybody know if this system is actually worth the 500-700 bucks i see it selling for? and does it just hook up to the mach 460?
