For what it's worth, I just replaced my head unit (CDR-23) on my 03' C4 Cab with a Pioneer AVIC-F90BT and the shop never mentioned anything about replacing the stock Bose amps/speakers.

Suspected cause
It's just that if you do you WILL have to replace the amp AND most likely the speakers as well.

Suggestion
I can check with the shop, but the amp is a two channel amp bridged to mono straight to the sub.

Suggestion · Original poster
Is there an adapter I can buy that will do the trick without loss of sound quality or do I just need to bite the bullet and go ahead and replace the bose amp and speakers?

Suggestion · Original poster
What I was told is that I have the type of bose stereo that would require me to replace all of the speakers because of some integration limitations with the bose amplifier.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I tried searching in the 996 forum but could not find what I was looking for. It would be great if there was a way to use boolean operators to combine search words.
I have a 2003 996 and want to replace the factory bose stereo with a new deck. What I was told is that I have the type of bose stereo that would require me to replace all of the speakers because of some integration limitations with the bose amplifier.
Is there an adapter I can buy that will do the trick without loss of sound quality or do I just need to bite the bullet and go ahead and replace the bose amp and speakers?
If you have the MOST bus you need to replace the amp/speakers.... all the 03+ 996's have them.
My 02 w/Bose did not have this so I was easily able to install a double din Pioneer nav (AVIC-Z) that works fine with the BOSE.
If you do change it all out, what do you plan to do with the Bose components? I have been wanting to upgrade my OEM setup to include door speakers etc. In theory, it should eb an easy upgrage. But as this is Porshe, I am sure that my fantasy of a reasonably priced upgrade will be dashed ont he rocks of reality....
For what it's worth, I just replaced my head unit (CDR-23) on my 03' C4 Cab with a Pioneer AVIC-F90BT and the shop never mentioned anything about replacing the stock Bose amps/speakers. With the exception of adding an 8"subwoofer and aftermarket amp to power the sub, I left everything else alone. Perhaps my 03 did not come with the MOST bus? Nonetheless, I am now happy with the bass response and all the other goodies that came with the new deck ( Navi, DVD, Bluetooth, etc.)
Post it on the forum, in the past I have always heard that if you have MOST you must replace but if you know different there are many folks who will benefit.
Thanks!
Sorry in advance.....
That stereo looks awesome, but that speaker in the passenger side taking up all the space, that gets a thumbs down from me. just my opinion, not being rude or impolite....
I'm no stereo guy, but it looks like that amp might be powering more than just the sub.
To the OP, the MOST system/amp has a fiberoptic input, Therein lies the problem. No aftermarket stereo has a fiber output, and there are no "Modules" that will convert RCA to fiberoptic. Some shops will propose to run the Bose speakers from the head unit or a new amp, but the problem is that they are not designed to do this. The Bose speakers are low energy units designed to work with Bose "digital trickery". If you use the speakers without the amp all bets are off as far as sound quality. Plus you may blow the speakers prematurely, and then have to replace them anyway. That is why I HATE the stock system.
No worries, unfortunately there's really not a lot of places to put the sub in a Cab. Objective was not to use any backseat space or trunk space as this was only for "cargo", groceries, luggage for trips out of town, etc. The Mrs. was more than accommodating in giving up a little leg and foot space. The space taken isn't really that bad and not uncomfortable unless you've got olympic power lifting thighs/calves
and half the time the seat's empty- so it's minor sacrifice for the low end that is so blatantly missing on the factory sound system.
I guess what we would like to know is what EXACTLY he did, and how you like the sound. If it is powering only the sub then is he powering all the speakers directly from the head unit?
Thx Medtech, that is exactly what the shop told me....was just hoping there was an adapter out there...oh well.
One thing I didn't like was the waaaaayyyy overpriced components he quoted me and the ridiculous labor he also quoted me. Taking my business elsewhere for a $1000 bucks less. That $1000 will go to my stripper fund haha
Perhaps, I do know the factory amp is still connected and tucked away in it's spot next to the spare in the truck. I'll be able to get the exact verbage of what was done this weekend when I stop by the shop. The sound is far from audiophile quality but the sound is good and acceptable for a mobile sound system.
lol on the pre 03 love, but know this, my system will sound better than Bose stock amp and speakers!
I have been meaning to upgrade anyways, just decided to get it done now. I already put a sub and amp in there and I amazed at the amount of base that can come from an 8 inch sub.
check over at 986forum.com. i know a lot of the boxster guys have messed with this. i believe there is a current solution that emulates MOST; basically, you buy a converter. the new head unit hooks up to the converter & the converter ouputs to the MOST components.
Stereo-noobie question: Is the 2003 NON-Bose stereo also a MOST fiber-optic system? Just curious since my 03 non-Bose car came (to me) with an Alpine head-unit and a pair of Alpine digital amps. I'm wondering how that's possible given what the above posters have stated?
It's possible. It's not that you can't put an aftermarket stereo in. It's just that if you do you WILL have to replace the amp AND most likely the speakers as well. This of course doubles the cost.
This is a source reference. Confirm exact model applicability in the original material.
