There's definitely a good amount of features lost when you delete the PCM. Of course you touched on the major ones like parking sensors. There's also navigation in the cluster, control from the wheel/stock, and the trip log features, etc. The backup camera can be retained, but you'll lose the dynamic parking lines. It's definitely a sacrifice to some extent, but it does pave the way for perfect audio signal into an aftermarket sound system like the Stage III upgrade. The low-level outputs from the alpine can directly feed the new amplifier and yield phenomenal sound.

I am looking more closely into this Alpine head unit replacement. I assume we bypass the whole Fiberoptic Network? This will save a ton of adapters etc? I just assume we need the adapter for power and signal to the speakers via the Musicar Kit and we just wire up the aftermarket headunit for power, USB and low level RCA's to underneath the passenger seat?

Sounds relatively reversible and simple.

Right on par, Joe. No more Fiber-Optic needed once we ditch the Bose system and the PCM. Just run a single pair of low-level RCA's down to the new amplifier. I can even build a harness that plugs directly into the Bose amp plug so there are no wires cut. You'll need to either use a CAN-Switch or run a wire up from the fuse box for a "turn-on" lead for the new radio. Factory PCM has power and ground but there's no ACC back there since it's all done on data right now.

All reversible, just need to be able to live without those extra integration features from the PCM. We've replaced the CDR31 in a Boxster in the past using all the same parts the 991 would use. Not a bad looking solution, and with the Alpine iLX-107 it would look even better!

Hi Nick..
Interested in upgrading as well. Is there a 991.2 Cab Bose solution yet? Recommendations for NorCal ? Would gladly sign up for the same solution as the Club Coupe above.

Both the products and installation appear to be first rate.

I had done the Stage I (tweeters) in my GT4 last fall, and I recently added the Stage II and Stage III. I am equally pleased by the results (outstanding audio and seamless integration with PCM) and by the fantastic experience of working with Nick, who patiently answered all of my emails as I considered taking the plunge, and then worked with my installer on his questions to ensure everything was working well and just as intended.

I had expected when I got my car that I would have to live with lousy audio inside (albeit glorious noises coming out the pipes at the back), but thanks to Nick's ingenuity and dedication I now have great sounds all around.

Also, for those in the Trip-State area I had a great experience working with a mobile installer who did this work: Eric Jones at http://www.carinstallations.com/. He's meticulously careful and thorough. He's also very pleasant and very knowledgeable; I would recommend him for anyone considering this kit.

Are there any upgrades available for 991.2 with Burmester?

I'm curious since I have listened to the Burmester in 991.2 using CDs, not using crappy, lossy MP3s....are you unhappy with the Burmester sound quality?

I thought it was awesome.

I'm building a 911 now. Trying to decide whether to go for the $$$$$ Burmester vs. getting a base & replacing "everything" with something like the Musicar Stage III, detailed here.
Bose & Burmester come with 12 speakers, the base unit comes with only 8 speakers.

I think when you get the system replacement detailed here you end up with 8 speakers. Not sure if you must lose any PCM functions, such as parking sensors, which would be a deal killer for me.

My daily driver has a custom audio set-up, so my bar is high, but I have not been happy with bass response, which isn't linear. In addition the frequency roll-off is a bit too high, some of the lower frequencies just can't be reproduced. The staging is decent however, so speaker placement is not bad.

Thanks, would you buy a tweeter or woofer or amp upgrade, based solely on the opinions of others, w/o actually hearing the new system in a 911 1st? I can see doing that if you have the junk, base system but, if you already have the Burmester, I would think you would really want to hear the proposed upgrades yourself with your own familiar, favorite, lossless music... b4 deciding.
