My thoughts on the Bose Audio system
From Pandora's help page: Pandora on the Web plays 64k AAC+ for free listeners and 192kbps for Pandora One subscribers. All in-home devices play 128kbps audio, and mobile devices receive a variety of different rates depending on the capability of the device and the network they are on, but never more than 64k AAC+.

In addition to the above, I don't see many mentioning two other "tweaks" that I feel make a big difference toward improving the overall sound quality within C7 Coupe's (audio compromised) cabin.
1. Go to the Audio Mode settings and select NORMAL. --- I believe this is the closest to "natural" audio, without (too) much digital enhancement. You might prefer DRIVER, which would be my 2nd choice. However, I highly recommend steering clear of CENTERPOINT, as this mode is way too digitally enhanced and incorporates the Center dash speaker way too much (IMO).
2. I highly recommend you experiment with shifting the speaker Fade/Balance from center/neutral toward the FRONT speakers by 1 or 2 notches/presses. I find this tweak provides improved sound across all frequency ranges and provides improved volume levels without having to pump the actual volume too high.
Hope these recommended "tweaks" helps some of you squeeze some better sound and more enjoyment from your C7 audio system. --- It would be great to hear from anyone who finds they've experienced an improvement. Best of luck to all!

Thanks! Really sounds pretty damned good now.

2017 2LT, ITunes music saved in an Ipod:
I set my tone about as described in post #13 but a little more bass, perhaps because we have a couple of coats in the rear cargo net in front of the rear speaker. That seems good. Balance/fade set a little forward/left.
Our Audio Pilot is On, I don't find it's adjustments to be excessive. If anything, I'd like more adjustment from it.
Sitting in the car stationary but with the engine running, the system actually sounded best in CenterPoint. I'll need to do some more experimenting at speed to see how that works out.
Don't be afraid to experiment to find out what's best for your ears and your music.
EDIT:
The large horizontal piece of our C7 cargo shade is installed, but the smaller forward piece is not, and that may effect the sound somewhat. The big one-piece cargo shade in the C6 was claimed to produce a noticeable noise reduction, one guy who did decibel measurements actually installed a double stock shade and said that helped even more.

Things like autopilot, centerpoint, driver, vs. normal are all more personal preference.

I've been involved in high-end audio since 1960 and ended up with nose-bleed expensive stereo gear of the best reviews and quality over a 50+ year period.... no speaker system - at any price - compared to the 901s, Series I, in my experience. I truly regret the day I sold them.
Some of the brands I currently have in my racks: Onkyo Pro, Marantz, Emotiva, Oppo, Cerwin Vega, M&K.

Direct007, try moving your settings to those in post #13, and move your fader two clicks forward and tell us what you think. To my ear, you have too much bass and mid-range for the Bose system, and it sounds brighter with the fader more up front.

However, a audiophile home system is the baseline for reproduced sound.

FWIW, Jaguar F-Type offers a Meridian system as an option and Porsche offers a Burmester system as an upgrade.
Hell, my $46k Grand Cherokee has a Harman Kardon system that crushes the Bose.

It will never get even get close to a good listening area! The C7 (at least Coupes, Verts are reported to be somewhat better) is very noisy! The Michelin tires (worse in my Grand Sport than my Z51) and essentially no sound insulation make it far worse than most cars. It was built for performance, which is why I buy Vettes!Reading posts from folks who put in two layers of quality insulation say it helps BUT those with before and after db data, not enough to make a major difference.
Below is a pic of what you are up against, especially the thin aluminum on the rear of the seats and the driveshaft tunnel.
For those that listen to music with very heavy bass, the doors also vibrate! Before spending any money trying to "fix the audio components" or blaming Bose, better to try to add sound insulation best you can! Or just enjoy what the car was designed to do!

And check out their speaker cable prices under products, it should give you a good laugh.
You can create a sound system in a car that certain individuals will love and others will hate but to try and create a car audio system that provides a truly neutral reproduction of source material really is trying to make a silk purse out of a sow's ear.

I know what you are talking about. Being a former audiophile, I have gone thru rehab and am now fully recovered!...my motto nowadays is "bang for the buck." I think audiophiles can have a tendency to go down the road of diminishing returns.

I extensively soundproofed my GS, not specifically to improve the audio sound, but rather to improve NVH. Here is the link:
https://www.corvetteforum.com/forums...and-sport.html
One improvement the soundproofing made was to improve the sound of the OEM Bose system. I can't say that it sounds great now by any means, but it is much, much better. Surprising, before the insulation I thought the "centerpoint" mode was the worst sounding mode. Now it may be the best.






Foosh made a good comment, some folks just like to complain.

I also have a Jeep w/ the HK, and had an M3 w/ HK. In the Jeep, I think it's equivalent to the Bose, but large cabins have better accoustics. There's more room for channel separation, among other things that enhance sound.
In the M3, I wasn't impressed with it at all, and the M3 forums were also on fire with customer dissatisfaction with it. When I read the "stereo sucks" threads, all you have to do is change the name of the manufacturer, because the words are always the same.
My wife had a premium Burmester in her '15 MB, which she recently just dumped in favor of the new Infiniti Q60 RS400 coupe. We thought the Burmester was very bland with inadequate bass. The Infiniti sounds great with a (wait for it) Bose Premium system, which she and I both love.
