Well, I've just finished the first part of my upgrade to the Sound System Plus (SSP) in my C4S.
I've replaced the bog-standard (and pretty useless) tweeters with a pair of (dismantled) Dynaudio Esotec MD102 and machined up a couple of delrin adapters to fit them in. I also got a pair of Burmester tweeter grills to cover since the original grills won't fit over the tweeters without modification.
The result is really excellent! I can now hear the drum hi-hat clearly and there's a good, resolved sound stage audible now (absolutely nothing before - really mushy). High guitar notes are clear and present; stereo separation good. All in all, I'm more than satisfied with the result: it's considerably better than I was hoping for.
This is the first stage of my proposed complete replacement of the SSP.
The next stage is a simple replacement of the door woofers with some Audison or Focal 8" woofers (I'd love to go for Dynaudio woofers but the price is horrific). The main trouble with door speakers is that, well, they are attached to *doors*. Doors wobble and flex. In contrast my standard BMW 8" woofers are bolted to the floor pan underneath the seats and sound excellent (why didn't Porsche think of that?) I'll probably add some sound insulation as well.
Then I'm going for a decent sub-woofer (Focal 5" 13WS probably with a Rockford Fosgate amp). The main problem here is manufacturing the adapter for the sub-woofer under the dashboard. It looks doable but will need some thought.
The final stage will be to replace the ASK amplifier with a Mosconi 60.8 DSP. I'll scrap the middle console and rear 4" speakers in the process - I don't think they add much, if anything.
I'm adopting the rule that everything must be a) reversible and b) fit into standard locations - no boom box on the back shelf or amplifiers in the frunk, thanks.
I got lot a lot of these ideas from a Rennlist thread on upgrading Bose, so kudos to the pioneers over there.
I'll post a couple of pics later showing the Dynaudio tweeters and adapters.
Burmester - eat your heart out!
