Does the awful sound improve when you upgrade the head unit?
I have the "premium " Bozo sound system that is by far the worst I've heard in any vehicle. The stereo imaging is so unbelievably terrible the audio sounds like it's coming from the center of the car, but I've verified all speakers are working by using the balance and fader controls. Don't get me started on the flat frequency response, and it's not in a good way like high quality studio monitors. It's because the system is incapable of accurately replicating sounds from the original recordings.
Anyway, I'm thinking about using the nav-tv most hur 955 to update the stereo, but wanted to get some feedback as to how much the sound improves while still using the original speakers. Will it still sound terrible if I do this?
Thanks

I haven't upgraded the sound system in my Cayenne yet. I'm really considering it. I did replace the Bose system in my 911 with a new head unit, amps and speakers. The difference was dramatic. I can't speak from personal experience on the Cayenne, but I can tell you this: most people consider the speakers to be the weakest link in the system. If you really want improved sound quality, then you should consider speaker replacement. If you want updated features (Sirius XM, Bluetooth, updated navigation, etc.), then replace the head unit.

+1. I strongly agree. Apparently, the Germans (Porsche, BMW, and MB) got suckered into adopting the MOST fiber optic bus for the audio system, and compounded the error by falling for Bose's "audiophile" snake oil. You need a $650 FO adapter (google "MOST HUR") to interface with an aftermarket head, and then you're still stuck with the terrible sounding Bose crap. Further, Bose speakers have odd impedance and may fry an incompatible amp/head unit if you try to bypass the Bose amp. Or you can rip it all out and start from scratch...a very costly upgrade.

Additionally, if you don't regularly have anyone listening to music in the back then you can waste a lot of money on "good" speakers back there what will provide very little improvement over much cheaper options (including staying with stock speakers).

While I don't consider the Bose system to be audiophile grade.. The system in my pig sounds pretty decent. I'm not a fan of what happens with the surround sound on. I also have to turn down treble and boost bass. The system definitely sounds better than those in my previous vehicles.

I realize there are much better systems. I added a JL Audio stealthbox subwoofer and alpine sub amp to my otherwise stock Bose system. Several people, including 2 "audiofiles" mentioned the quality of the system sound.

This is a pretty old and well talked about subject
Given that the system may have been, in part, designed by a member of this board, who will tell you that Becker and PAG compromised a good design for their own reasons, its hardly surprising we get a less than perfect result.
I have to say however that I have been in MANY Cayenne since April of 03 and the sound quality does vary from car to car, I have been lucky with my second on which sounds much better than my first. I think mold sets into the speaker cones and the amps drift off spec with older models, I personally saw what I took to be mold damage on the first car when I had it apart from time to time
Not that I am saying that's age is the only reason, some were variable before age could even set in.
beta owners had lots of loaners.

I agree with Mike's comments. The Bose system in my Cayenne actually sounds pretty good. I think it could be improved, but for everyday use it's not bad at all. The Bose system in my C4S was another matter...
