i only have one in the relay box and it doesn't have anything to do with the sound system but it's good. 9 10 12 are good.
i also have no current to my left rear tail light if this means anything.

The final output amp for your '88 are internal to the radio, and run on the 12V provided through that #9 fuse (on the '88 - later years move this fuse into the relay box). You radio's output is 2-channels (stereo) in 4-wires -- these wires are in the largest of the 4-plugs in the back of the radio (3 plugs if you're not counting the antenna) - the speaker output wires are kinda in the center of the plug - so they don't often come loose,, - but pushing the plug back in never hurts - wiggle the harness as you do (radio on / speakers output med/low vol) to see if you hear something as you wiggle- Wires do break, but you'd need to have broken two to kill 2-chanels of output...(assuming you had 2 to begin with)
The '88 didn't ship with rear speakers, so you've got some aftermarket addition to address those. Every "kit" for adding these speaker would have a fader of some sort as part of the kit.
If you've got covers off - there's 3-connectors involved for the rear speakers - all are above and forward of the reverse lever...
If you don't have the left-inner fairing off, look around for a strange knob -- often just the shaft of a potentiometer, and most that I've seen came with a horrid brushed-aluminum maybe 5/8" diameter knob. Since the mounting of these was left up to the customer, they can be anywhere - The key surround panel is common, as is the left pocket (or just setting the thing to some value and wadding-up the harness and stuffing it somewhere).
If you discussion of "messing with the headsets" was in/around the driver's headset pigtail, you'd'a been in and around (and possibly under) the left pocket where things could be squished and/or disturbed...
I would strongly recommend hunting for the fader harness - most are fragile and of poor quality, and one good tug or push can change them from working to INOP in about a second. This photo shows the stereotypical fader control bit on the right (see the knob) - many MANY are like this (wires in a smooth tube and not an OEM loking flex shield or tape wrap):
