probably the amp...when it goes out...you have no sound.

93-94 used a completely different amp part number than 95-98.
the one you bought is probably for a 95-98.

I have a 93-94 amp I can sell you.

$50+ shipping.

I have removed/wired/fixed several sound system problems in numerous Mark VIII's. Very rarily was it something other than the amp.

The other devices in the rear amp tray are

phone module
compass module.
