hey man, i drive a 1983 CJ7, and the SAME EXACT THING happend to me, it rained hard one day while i was in school and my jeep was in the parking lot. when i got out that day and cranked it up the speakers just put out a loud screetch like a record screetch. then they just stopped working. my subs still work fine though. but i have 2 round speakers, 5" or 6" in the dash, not sure, and 2 6x9's in wedge boxes just laying in the back seat, so i dont think water could have got to them because i have a hard top, i took my 6x9's out of the box to make sure everthing was hooked up right and it was. not sure what it is. i cant figure it out, so ive been driving around for a couple of weeks with just bass, and its starting to **** me off lol. any help?
