Bose amp sudden death
Posted: Wed Jun 17, 2015 11:10 am
My Bose amp (28060-EA500) seems to have cashed in its chips. I started the Pathfinder yesterday after work and had no audio.
Here is what I know:
The symptoms almost make me think it could be just the lone (I think there was just one) large-ish capacitor, although it didn't look bad - no char marks, no bulging.
Aftermarket will require the replacement of speakers, and either the head or an amp, and butchering of the amp harness (unless I can find the female connector).
The car has ~143k miles and is 9 years and 3 months old today. Realistically, I think I'll have the car 2-3 more years max.
Has anyone successfully repaired one of these, know of a good place to send them for repair, or have one laying around from when they replaced the entire system that they want to get out of their parts bin?
Here is what I know:
- amp is getting +12v at the harness
amp ground tests OK with multimeter, also no corrosion, etc. on connectors or the amp bracket
all 4 channels from head unit have audio at the amp connector
head unit seems to function normally
amp is putting out very subtle/quiet click/pop noises on all 4 speakers consistently with car on and headunit on or off - you can listen if you are bored: https://dl.dropboxusercontent.com/u/559 ... d_0002.wav (it is VERY quiet - this was recorded with my phone against the speaker)
after waiting 4 hours, I still had no audio
after waiting overnight ~9 hours, I had audio for about 3 seconds, nothing for about 3 seconds, then audio again for a few minutes, then back to dead
the inside of the amp looks good - nothing burnt, no obvious cold or charred solder joints, etc.
- I have not tested the amp turn-on lead - is it +12v, or something else?
There isn't very much inside this amp, but I neglected to snap any pics and I don't know exactly what is inside
