Did anyone ever figure out the speaker problem? The speakers in my 08 passenger side speaker was working intermediately and now the drive side is doing the same thing. Thanks.

 

Apparently there's a few causes to the issue.
1. Speaker burnout, of and by itself. Hardly surprising, if you have looked at the iffy quality of your average OEM speaker.
2. Speaker connections, and wiring, at the speaker end/
3. OEM 12 decibel/octave crossovers, both cheap, and relatively weak, can cause a cascade speaker failure,
especially if the stereo unit is turned up loud, for long periods of time.
4. A faulty dataport adapter, which will also effect your seat-belt chime.

Note: This issue didn't appear, till after GM removed the Radio port from the ignition switch, circa 2002, and switched to the dataport adapter, which they use, now.

 

Ok, thanks; So I know before I start pulling things apart, What's the size of the OE speakers in the door? What are they(Woofers, subwoofers, 3way, 2way)? Thanks.

I had the same problem with my cruise control, I replaced the brake switch sensor and it started to work again

 

Have you had the vehicle inspected for this issue?

Isn't the point of asking about this on the forums to avoid having to spend hundreds of dollars just to have them tell us that the speakers are crap? I've been having this issue with my '07 LT for as long as I've had it. I get that maintenance is necessary with all vehicles, but if the factory speakers are bad they should be recalled. They did with the air bag systems. If it's the manufacturer that puts in low quality and defective parts, should fixing the issue fall on the consumer? Should we have to pay several hundred dollars to fix something that shouldnt have made it to production vehicles? I believe the answer is no. And it would behoove Chevy to step up and fix this issue with a recall.

 

It's the brake switch that's missing up

 

Have the same problems. Break pedal sensor fixed my cruise control issue. Door speakers suck. When it’s cold and the sun is on the driver side during the day then that side will work in the afternoon. If the sun is on the passenger side then that side will work in the afternoon. I have RPO UQ3, 6 speaker, not Bose. My understanding is the weather seal at the base of the door window allows plenty of moisture in and it gets all over the speakers. Over time, the crappy speakers get worse. Replacing the speakers is great. But, adding speaker baffles would help protect your new quality speakers from the moisture getting in the door. Of course you can also replace the weather seal for the windows too, but I would rather protect the speaker and add a couple drain holes to the bottom of the doors.
