I was listing to the radio in my Jeep today and my friend in the backseat said that there was no sound coming from the back only the front. I never noticed this because ive never been in the back with the radio on. So after hearing this i did just that and I noticed that the two speakers in the sounbar weren't working. I know this sounds like an odd problem because ive heard normally this happens to the front door speakers not the ones in the back while the front still work. My Jeep is a 1998 Jeep Cherokee Limited, if anyone can help please let me know how to fix this problem.

 

check wiring and all

 

^^ agree this is the only thing you can do....FIRST IMO make sure wires didnt get pulled out from behind speakers
next
Check all the spots where the wire could possible be pinched door jamb etc.....
if still no good then Start following all the wires til u see prob

 

Given how easy it is to get to the rear speakers, and that a wiring problen is uncommon for the rear speakers, I might first check to see if they are blown. Then I would start tracing wires.

Hey Greensburg!! I am in Irwin!
I see that Pats Stereo shop out near you. They have some nice stuff there.

 

Thanks guys, i appreciate it. Yah im gonna go out to the garage now and check out the wires and such and see if they are blown or there a wiring issue.

Nice! Yah thats a nice shop i think im gonna buy some stuff through them.

 

So i was incorrect that i had speakers in my rear doors, they were just slats indented in the doors to look like speakers, but i do have two speakers in the ceiling (attached images). And those do not work, does anyone know where the wires for these speakers are or if there are any fixes short of replacing the speakers.

 

disregard this, problem fixed. Need new rear speakers.

 

so I bought a used 1995 Jeep Grand Cherokee Limited and inside the speakers were not working so I went out and bought everything to replace it new head unit and all and I went and tested it and nothing is working no sound nothing just the head unit works. Does anyone have any idea what could be wrong with a fuse or some sort of wiring it's really bothering me. Any help would be greatly appreciated

 

Maybe someone in Stock Grand Cherokee Tech. All ZJ/WJ/WK Non-modified/stock questions go here!ZJ (93-98), WJ (99-04), WK (05+) might know.
