850 rear speakers Topic is solved

My rear speakers have gone out, both at the same time. Is there a connection anywhere besides the rear of the radio where these might have come loose together? The radio and speakers are all stock, if that helps at all.

Thanks.

Well... if the both blew out at the same time, i guess thats suspect for something in the deck... but you could check the actualy speakers with one of those electrial current tester things to see if by chance the speakers just happened to die.

It will also tell you if any current is actually reaching the speakers at all. And if not, then like you said, it may be at some other connection besides the back of the deck. Or it could be the actual deck itself...

Its possible that you put something large or bulky in your trunk and it probably knocked off the connector and tore both wires. Hey, its possible.

If it was the deck, then more than likely the output transistors blew out (not sure why this would happen). Its also possible that the fader switch is a bit dirty and just needs some cleaning (move the fader up and down several times).

Speakers rarely ever give out, and especially both at the same time. I would do the conductivity test in the above post to rule out the wiring/speakers first. If it passes, the suspect the deck.

I had both of mine(rear) go out once. It was the amplifyer in the radio itself. It has two, one for the front two speakers and one for the rear. It went out because one of the speaker wires got pinched between the speaker and the back deck where it was mounted. When the wire insulation failed it caused the speaker wire to ground out to the frame, thus causing the amplifyer to blow out over time.

Check the wiring to each speaker closely.
