hey all. I have a question. I used to have a mustang that had the mach 460 system in it. I changed the cd player to an aftermarket and it sounded awesome. I now have a 94 gt which does not have the mach 460 and I have changed the cd player and all 4 speakers and it still doesnt sound as good as the one with the mach 460. whats up with that? also I have 1 amp under the cd player, even if i dont have the mach 460 system can i use that amp? what plugs get connected into it? I have like a bunch of plugs behind the stereo.
