This used to be my vehicle, I believe the problem is that either the paper in the speakers has dry-rotted and cracked (120 degree temps here in the desert), or the head unit is dirty (sand from the desert here). The system was a complete oem mach 460 setup, speakers, harness, amps, head unit, etc. The tweeters I mounted behind the dash speaker grills, not in the doors under the mirrors. The 10 disc changer was from the same year town car, I simply grafted the oem changer harness into the oem mach 460 system, not hacked as I used the engineering schematics from both vehicles (not the evtms). The system used to sound tremendous when I first installed it back in the 90's, as I said before, I suspect time and heat has taken it's toll. FYI, I have another new mach 460 system that came out of a mustang convertible of the same era, all speakers, amps, harnesses, head unit/cd player, etc. All sitting in boxes...

I would agree, or after determining what the problem is, he could ask me for replacements...although I believe he is currently concerned with bigger issues.
