Bose Stero Question
I am trying to understand the system configuration. I know there is the head-end unit, CDM (Under the dash) and speakers which I believe each speaker has its own amp. I have a 92 ZR1 and the rear speakers don't work and pop loudly even of the balance is set to have all the sound going to the front speakers. This happens at both speakers. The front speakers sound a little "thin" as well. I suspect it is the CDM.
What I am confused about is there also appears to be a module between the CDM and the rear speakers on my 95 located behind passenger seat. I did not see this on my 92. Is this another amp? My plan is to test everything with working stuff before I replace the CDM.
Thanks

The CDM is just in a different location. The CDM still provides the same function regardless of location in the car. There's NOT anything additional in your '95 IF it's still the way the "General" assembled it.

Also, I just swapped the speaker amp from my 96 into one of the 92's rear speaker and it worked. Going to check passenger side now. Ecklers is running an 18% off discount on anything until midnight. Figured I would jump on the deal and get a couple of new ones.

All the amps in those Bose systems are known to fail. Keeping them running can be expensive and while they are state of the art back in the day they lack a lot of modern features. A lot of people swap the entire Bose system out when it fails which you pretty much have to do since their parts are not easily compatible with anything else. If you do that you should box the Bose parts up and retain them for when you sell the car.

Listen to the tunes and pay attention to the road ... you don't need all of the rest of the "killer" electronics that everyone worries so much about having.

Here are some useful links for repairing Bose amps if you are handy with a soldering iron. Also the amps out of a 95-99 Nissan Maxima and Infiniti I30 will work and are a lot cheaper.

Bose Stero Question
I shipped each speakers Amp to www.carstereohelp.com and had them rebuilt.
All 4 work great now.
About $250 total for all 4.

C4 Bose Amps
Capacitor C172 affect volume and sound quality
Capacitor C7 & C8 worling and squealing
Capacitor C31 poping sound
Capacitor C203 Base disortion
Capacitor C16 Poping & squealing
Capacitor C19 & C 25 Generally don't go bad
The rest will make the squeaks and squeals

For under $400 you can re-wire and install a modern stereo and speakers that will sound much better than the two decade old Bose. It's the best thing I've done to mine. Budget a Saturday, and you can have it done in time for an evening cruise.

My 1984 C4 had the lower end Delco AM/FM/Cassette instead of the Bose... but I've been really happy with the modern Kenwood KDC-BT762HD deck I put in along with Sound Storm Labs speakers... SSL GS-246 4x6" 2-way in front and SSL GS-369 6x9" three way in back. The head unit will play MP3 from the CD drive, has Bluetooth, HD Radio, front USB, AUX jack and is SiriusXM ready. All features you won't find on a 20+ year old unit. Cost for all the hardware including a wiring harness and antenna adapter and a mounting kit was under $300.

I recall my Dad's Zenith transistor radio from the '60's.
I can barely listen to any Blose sound but grin ever time my upgraded Corvette system is fired up. Some days I get nothing else done, with the help from a battery charger and the good leather Corvette seat!

the lauded (by some) Blose 901s were assemblies of lots of cheapish drivers all equalized to hell and back. An A/B listen against some high quality speakers demonstrates this quickly and definitely. I did that with a pair of Klipsch LaScalas (a hundred years ago) and still remember the impact. The Bose ad budget is killer and effective. the sound, IMO, horrible. The optional sound system in the '84 was quite a revolution, however, from the ultra-crappy previous options, so the lauding and legend was given new life. the company was always mass market and hence, of middling quality for those who demand an excellent listening environment, not than any car will truly be audio nirvana.

Pio head,4x100W MBQuart,Inf 8"+6.5", from my signature. ' Pio' is the head unit, which I am not a huge fan of, for their mediocre support, but I do like the sound retrieval for mp3s. It was NOT done in one day, with mbQuart low-profile amp under the pax seat and self-made speaker enclosures for the door 6 1/2" and the 8" sub in the rear, not to mention the new, large speaker wires. I like Infinity products, but other high-end is good.
