So we have a 2005 Excursion that we bought used. The rear speakers are not working. I had an aftermarket DVD player in there that we have now removed. The stock unit (on the roof) seems to be have been dead and the display was changed with some aftermarket player.

The problem we have, however, is that the rear door speakers don't work. I pulled the speakers from the rear doors and tested them in the front door. They both work fine, so it's not the speakers.

I checked the harness in the center console to see about jumping the wires at the rear control unit (seen in other threads on the matter) but that did not help. I did find something odd that I can't seem to confirm.

Below is the harness I have in the center console. I have a question about this....



The harness connects to a plug coming from the center of the lower dash under the carpet. No problem there. I have two other connectors that go to the power port and rear audio control panel. Those are pictured below.



The audio controller plug.



I think the problem is that there are two connectors that don't have a mate. Below is what they look like.




I can't find any harness or wire bundle that may have been cut or spliced into anywhere under the carpet or under the console.

Is there some component that these connect to? An Amp? A DVD changer? Bottom line, I think those two plugs need to be plugged into something.

Any help would be greatly appreciated!

 

Anyone know what the connectors are in the last photo?

^as a bump

 

Nobody has a clue?

 

I just bought mine, so not an expert, but when I upgraded my stereo yesterday, it was explained to me that most stereos only have 4 outputs, and that 6 are needed to drive all of the door speakers. I elected to run the front 2 stock, and the back 4 thru a J&L amp( with an added sub in a box and amp in the back for bass). This is from a Pacific Stereo(Woodland Hills, Ca.) store that I've done business with for years(usually about every 5 it seems!). The original radio was designed to handle all 6.

May not be Gospel, but the guy has never steered me wrong.

 

Experience from my Expedition......

I recently replaced the factory tape deck with a DVD player. During the install I was verifying that all my speakers worked to make sure the harness I built was done properly. I noticed my rear door speakers weren't working. I verified the harness and started to think that maybe the DVD player itself was bad so I hooked up the stock unit again. Even with the stock unit hooked up, the rear speakers still didn't work. I ended up running new speaker wire from the DVD player to the doors. Problem solved.

Now I know that my Expedition doesn't have the rear entertainment unit that I believe your Excursion has- all it had was the rear audio controls. My guess is that I lost the rear speakers when I hacked up the rear audio control panel and put an inverter in its place.

 

Appreciate both of you taking the time to reply.

The main thing I am trying to figure out though is the additional plugs I have in the harness under the center insole on the floor.

My audio control seems to work in that it will cycle through the stations and go in and out from the DVD/radio etc. problem is the door speakers won't work.

What I am hoping to find out is what was connected to the harness plugs. One of those has a series of wires that I think run to the speakers. So it might be as simple as a harness or secondary amp that has to be run/replaced in there. Ultimately, if I can avoid a retire, that would be awesome.

 

BTW and FWIW, I had to trade in my 2ch for a 4 ch amp to make it all sound ok....I mean terrific!! The rcvr didn't have enough poop(50 watts) to keep up with the 400+ watt amps! D'oh!
