I ahve had my head unit for about a year. Just recently going home my speakrs all of a sudden stoped working. I have taken out my head unit and it is all connected correctly. Iam completely confused why would my head unit be working perfrectly but my speakers don't do anything. I know they work casue i hear some buzzing nosie right after I turn it on.

IAM VERY DESPREATE

Thanks for all the help!!

 

What's the make and model?

 

That's an easy one. Headunit is dead!

If it was one speaker or 2, I would guess wiring (or the headunit), but since it happened all at once, I think the HU died.

 

It's a little early yet to just call it dead. May be though.

 

Definately need more info such as make, model. Method of connection, type of speakers, whether theres an amp. Basic stuff...

 

I had a similar problem with my 83 Cutlass at one time with a Kenwood unit. It ended up being a wiring issue with one of the speakers and the system was set up so that if one speaker shorted out (or whatever) they all went out. Check your speaker wires before you go throwing down a couple hundred for a new head unit.

 

I was playing with the wiring and i was able to put in both front speakers but as soon as i pluged in the rear speakers to the HU they all shut off. But if i put the rear speaker wires half way in they both work.

Iam trying to think i don't want to but a all new wiring harness without knowing exacly thats the problem.

I have a 1991 Camaro RS

I think regardless of the make/model, although it would help, you either have a bad speaker or a short in the line.
First get a DMM (multimeter), Remove Head-unit. Then take the DMM and put it on ohm read. Connect the leads to the positive and negative wires of one speaker. If it reads 3.2-5ohms you are good and probably have a bad wire. If it reads outside the ohms listed before you have a bad speaker.

To determine whether the wiring is at fault, remove the speakers and head unit. Take the wiring to the speakers from the front and, using the ohms again, take the wires individually (i.e. positive on one side) and connect one side of the DMM to ground, the other to the wire. When you do this if it goes to 0ohms you have a short, or grounded wire. Do this to all the wires leading to the rear to determine which wire is at fault.

If all of this checks out. Bad Head-unit....
Without this basic troubleshooting procedure all else is simply blind speculation. And all anybody can do is guess.
