Bose sound - am I going nuts? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

The Bose system in my 03 and has done the same thing a number of times. Restarting (rebooting) the car often does the trick, but if not I've found disconnecting the battery for five minutes works every time.

I've never had that happen, but this is the only car I've ever had with a radio that will change a preset station to a completely different station if the signal is weak. 92.3 decides to change itself to 100.7 at any time it happens to feel like it.

If you don't mind my $.02 worth. You say the "Bose" system, unless all the system signals go through the amp in the front truck I don't think you can blame Bose. I'm sure some speakers are powered through the radio itself and if that's the case you problem is with the radio and not the Bose system.
I just checked my Bentley manual and the wiring diagram shows all wiring for the speakers, with the Bose system, run through the amp. So it's safe to assume that the amp is somehow overheating and tripping a thermal fuse. Once the fuse cools and resets the speakers are powered again.
Check to insure you don't have anything laying on or around the amp that might impede cooling air from circulating around it.

Same problem has happened to me, came back after shutdown and restart.

I've got this problem only mine has not fixed itself. Do I send out the amp to be checked?

I've had similar issues with my Bose system to....even on a cold night not that long ago. There is more to it than the amp sometimes overheating. It seems to be a common problem and nobody knows how to fix it.

Bumping old thread. Anyone find a permanent fix or the problem to this yet? My car does this almost daily after the 2nd start up of the day.

I bought my 03 boxster about 2 months ago. Could not get the cd player to work. Tried everything it just would say loading and never get anywhere. I pulled out the manual on the radio and read it (didn't read anything that I wasn't already doing). Got in the car started it and the cd player worked like a charm and has worked ever since.... weird juju.. I know the porsche peeps are good but go figure you have to read a manual before it will operate; how did they ever figure that out??? lol

Wow, gotta stop reading the bad things on this forum. Wrote the above; took the car home for lunch coming back to work speakers go out !!! After arriving at work let the car sit for a minute then restarted and they came back on... sounds like amp getting overheated?

I hope you realize when you disconnect the battery for more than 5 minutes, you completely reset the ECU, it's settings and "readiness". Takes at least a week to remap once disconnected. I'd find another solution...
