We bought it new in 2010. It's the wifes commuter.

After several minutes the radio starts to decrease in volume then it slows way down and then stops. Craziest thing I've ever seen errrr heard.

I planned to buy a new stereo but a coworker told me it might be the amp.

Any suggestions??

If the radio and display continues to work but the volume goes down automaticly, without seeing that the volume number decreses, then I should also say that the internal amp has a problem. In some small cases it could be a short circuit in the stearing wheel volume control.
What you could do is opening the radio so you can see the circuit board with the amp module, connect the radio to the harnas again and let it play. When the volume goes down again, spray some special "cold spray" for electronics on to the amp module and see what happends.
When sound comes back again, the amp module is to be replaced. By your self or a specialised person with a welding tool.

If this goes to far for you, just look around for a new (used) head unit. The are not that expencive.

Crutchfield said they do not have a replacement for the amp.

So I'm stuck. I can replace the head unit and then find out the amp is bad. I don't know how to bypass the amp. This sucks

The JBL head unit cannot power speakers by itself--unlike other head units it has NO built in amplifier. I don't know how to test it, but it seems more likely the amp has failed than the head unit. Sometimes you can find the JBL amps for sale on Ebay.

If the JBL head unit has no internal amp, then there must be a separate amp somewere in the car... Which location is most common then?
In this case you could decide to buy a new external amp en replace it.

My google search showed it is behind the rear passenger seat in the side panel. Ebay is a great idea

The RAV has been at the dealer for 3 weeks. They can't figure it out. Twice they changed out the head unit and said it was fixed. Before the wife got out of the lot it failed.

I guess it's good we bought the extended warranty.
