Bose rear speakers do not work
 

We'll, I've had my Boxster S for a little over a year, and just realized that the rear speaker set from the factory Bose system hardly works at all. Obviously, I'm not much of a hi-fi aficionado.

When I adjust the CDR-220 head unit with fade control biased all the way to the rear, I barely hear a sound from the rear speakers.

I had the rear speaker box out recently when I was installing an under drive pulley, and I'm 100% sure that I connected it back up properly, and it sounds the same as it always has since I have owned it.

So, I either want to fix it to work right, or remove this heavy POS that I am always lugging around autocross and race tracks.

Any ideas?

Thanks for your help.

LOL - yeah, and I wonder if someone might actually withhold info. on how to fix?

Anyway, I save all my stock pieces in case some future owner may want to return it to that condition, though I can't imagine why.

Honestly, I think it might be tough to troubleshoot. If you have a speaker you can wire directly into the amp outputs, you should be able to determine if it's the speakers or wiring;

That's probably where I would start. Not sure what that wiring harness looks like, but is it possible to swap the front / rear connections on the amp? Meaning have the amp drive the rear speakers via the front outputs? That might be another way to test out the amp vs speaker or wiring question.

Otherwise, put a multimeter on the outputs from the amp?

Agreed, plug a speaker into the cable that goes into the Bose rear box and see if you hear any sound
Just to be sure: do the rest of your speakers say "Bose" on them?
The reason why I am asking is that what you describe would make sense if someone would connect a Bose rear speaker to a non-Bose head unit/amp
The Bose rear speaker has the weirdest wiring I have ever seen and is proprietary to Bose
