Unhappy Raer Speakers only work when hot out???

Here is one that has stumped me.

The factory stereo CD player went bad and the Rear speakers started working only when it is hot out. I thought it might be in the head unit so I replaced the head unit no problems getting it in. But the problem is still there.

In the morning no sound from the rear speakers and then when it warms up outside they start working. When the speakers are working they are working with out any problems (they do not cut in and out).

Anyone have this problem before?

I am having the same issue with my wife's 03 Outback wagon. The speakers started cutting out last summer. So far I have had the stereo out twice, and replaced the head unit with same model, and swapped out some of the speakers.

My guess is a bad batch of head units, or a bad connector. I believe the HU is a P-125. Rob M.

I might guess a bad connector, if you're talking really hot. Metal expands when it gets hot, so it might be a loose connection that's just making contact properly when the connectors expand in the heat?

It's only a guess, but it does sound like an odd symptom...

SO replacing the factory connector work? I can do that but I would like to know that it was going to fix it before I did it. I can manage to put some wires together but any more then that is beyond my skill level. Good to hear that I am not the only one.

Please help!!!!

If it is a loose wire, you could simply pull the door panels off and check the connections, and see if the speakers start to work if you wiggle the wires. You could also check the harness on the back of the radio. It's doubtfull, but that area does get pretty hot when running.

Good luck tracking it down, these things can become a pain.

I have pretty much traced the wiring from the radio to the speakers, with no avail. The right rear speaker works all the time. The others pop on and off when the car is extremely hot or cold. It is a rarity that all 4 work at the same time. This has me baffled. Rob M.

I have pulled the door panels off and everything seemed good there.

I checked the wiring harness and it seemd good. I am starting to think it may be a bad connectintion on the factory end of there harness.

If anyone has had this problem or has a solution I would be very grateful..

Thanks

Default Speaker issues - Temp related

I have the same problem with my 2004 H6 35th Aniversary. If the car sits in the hot sun, the RR, RF, and LR speakers all work. After it sits overnight in the cooler air, only the RR speaker works. It sounds as if Subaru has some definite issues around this problem.

Has anyone tried to get factory help on this issue?

Do you have the “premium” audio system (Macintosh, Harman-Kardon) that has the power amplifier under the front passenger seat? If so, then there’s a good possibility the problem is there.

The amplifier is mounted to the floor and is not tightly sealed. Water and spilled drinks can get to the connector and the printed circuit board. This can cause corrosion and intermittent connections.

In addition to bad contacts in the connector, I’ve seen one case where, on a Macintosh amp, several copper printed circuit board traces were corroded so much that there wasn’t anything left. I had to install jumper wires in their place.

Default Radio Type

No, I have the "normal" radio. If it was the premium stereo, it would sound better(I would think).

There are no markings for any uplevel stereo package, and it only has speakers in the doors.

I dont eat, and rarely drink in the outback.

My 1996 Chevrolet Impala SS came with a better stock stereo than my subaru. It is 8 years older, and has had no issues at all. I wish I could say the same of my outback. It seems to be one thing after another.
