2020 RS - Bose rear speakers sound question

mashuga said:

Has anyone faded their their rear speakers to the back and barely get any sound.
Almost as the crossover is set to tweeters only.

There’s no low end in the rear even when fading to the middle.

Same here - my car is new - barely 5,000 miles, and I'll have it looked at at the first service. You?

Let us know what you find out, I already had my first service and have been avoiding going in just for the speakers.

The front soundstage is good for the most part. They either used cheap speakers in the rear doors or the crossover is set wrong.

I’m thinking about replacing the rear doors with some after market rears. Just didn’t want to waste money if it’s a crossover issue..

My Rs is a 2020 just hitting 7500 miles and I had my first service before I noticed it.

Also have a rattle coming from the driver side door that’s getting worse, but I don’t have much faith in a dealer fixing rattles from playing too much bass..

Mine are the same way. Very thin and tinny when all sound is pushed to the rears. Seems like it disables the subwoofer. I‘ve heard the same from others, so I think that is how they are meant to act (which seems odd).

Mine is also a 2020, purchased at the end of the model year. I tend to agree with what Jay wrote above - it disables the subwoofer and one hears only the tweeters. My son thinks there are little tweeters in the door that we're hearing, and not the main rear speakers themselves.
Here in Israel, the service intervals are in KM - the first service is at 10,000km, and I'm almost up to 8,000, so I'll keep you all posted. I had the same thought as you - replace with aftermarket.
One thing I should mention is that I installed front and rear cameras, and it just occurred to me that the installer attached the wires to the rear entertainment fuses - if that's the case, perhaps it knocked out the speakers... we'll see.
Finally, I note that the only real difference between a Cadillac ST5 and the Blazer 3.6 (I have the 3.6 Premier) is the number of speakers. One wonders where they are placed and how they are wired.

Bass roll-off, most vehicles are like this. Front soundstage is what matters. Don’t bother to waste money on rear speakers, it does no good unless you end up doing them all and getting an amp. I would most certainly do a DSP these days and worry about the fronts. Music is recorded in stereo, L/R…..it’s not surround sound. A DSP with time alignment will do wonders! I have a system on my 2016 F150 SCREW and it’s a dramatic difference.

I hear you... so to speak. However, the goal of these systems is to make the driver feel like he's in a concert hall, where one hears ambient sound at the sides, above and behind, while facing the stage.

What you're saying sounds like the idea is to make us feel like microphones.

That’s like surround sound, we have stereo….L/R. Pretty hard to replicate that in a vehicle that doesn’t have the speakers at or above head level to aim at you. Don’t think there is anything in the settings or hardware to even process that type of recording (Dolby or what have you).

Surround/hall sounds are mostly all the ambient noise….none in music
