Did the same focal upgrade as Petza in my old 997.1 using ryanm's speaker upgrade thread on 6speedonline. That thread touches upon the SPP models and how they are the same speaker wise except for the rear subwoofers which are missing in non BOSE. The thread on 6speed discusses how the speakers are powered, which is a mix of head unit and the AMP. Can't recall off the top of my head.
Currently upgrading my non Bose 997.2 C4S. Did the rear speakers which are the same as outlined above and over on 6 speed. Found information on the SPP which I attached showing speaker sizes. Monday will likely replace the door and dash speakers/tweeters. Went with Focal as recommended in 6 speed and also what I used last time. May replace the amp but that would be down the line.

In the 997.1 Bose cars, everything but the rear sub box is powered by the Bose amp up front. The rear sub box gets a low level output and has an integrated amp in the box between the low level input and the actual subwoofers. I upgraded the amp to a higher power Alpine and used Focal Utopia speakers in the box.

I'm going to drop some Focal IS-8 and Focal ISN-100's in the doors & up front for the tweeters & see how it goes. That's $450 bucks, and everything I want to do with an amp replacement approaches $3k really quickly...

This is awesome. I love how much time and love you put into all of your cars. Any considering this type of upgrades should also consider scan speak drivers. Amazing drivers for all budgets including those they demand the best regardless of price.

I actually have a 991, but I figured the systems were similar when I first started researching. I was wrong. In the 991 with SPP, all of the speakers are powered by the ASK amp. Go figure!

At this point, the long tent in the pole is waiting on the Burmester grills to show up from Suncoast (they're coming from Germany, apparently). So i'm just amassing gear & twiddling my thumbs!

I actually ordered a Helix V Eight DSP amp, and sent most of the speakers back without installng. I did upgrade the tweeters to some Dayton Audio tweeters, which sound much, much better than the stock ones. I was so impressed with the DA tweeter upgrade, I ordered some DA 4" drivers, the ISS-200 8" woofers, some larger DA tweeters, and some 4" DA coaxials for the rear (for rear fill). I'll leave the center unhooked, and the 8-channel Helix amp with DSP will give me a ton of flexibility to tune & play with the setup. It should fun!

I am actually going to be out of amp channels. 8 channels, and 8 planned speakers at this point. Nothing to drive the center with at this point.
(I'll have 2 unused Focal tweeters that came with my ISS-200s though, in case you can do something with three tweeters )

Would love to do a speaker upgrade in my 997.2 Cabriolet with BOSE. But, my sub is in the passenger footwell and I don't know where to start with the rest. Does anyone have information on upgrading a cabriolet? Picture is my car, but it's just for attention.

To change the speakers, you don't need to replace the primary Bose amp, just replace the speakers and if the Sub is a problem where it's located, just leave the stock sub in place. Where is the amp for the sub located in a cab and what does the sub actually look like - is it a box where you can find a compact sub to replace what's in the box after also upgrading the amp with one of the small alpine units? In a coupe, the subs aren't driven by the main bose amp - they get a regular signal and have their own compact amp in the sub enclosure, but I don't know what the cab setup looks like.
Might find something of interest here too - https://www.billjehle.com/PORSCHE/index.html

That's a really pretty car.

This forum gave me a lot of good tips while upgrading my sound system. I went with the focal ISS 8" component set and Focal RCX 4" auditors front/rear. I also put in a new jvc/kenwood double din head unit with wireless android auto/carplay. took me about 17 hours straight, start to finish in one day. Also added a backup camera. My car doesn't have a factory subwoofer so i thought i would spend extra on the 8" woofers. the sound is very balanced with a surprising amount of bass. Even on relatively low bass settings. Dont waste your time/money with the Boom Mat. It basically creates a vacuum behind the speaker and the cone cant move to produce the bass. I tried it on the first door i worked on and there was literally no bass. I could see the woofer wasn't moving at all. I loosened the speaker screws a bit to let air in and the woofer then worked as it should. In my install, every lined wire was the negative. I tested this based how the factory speakers were hooked up with a 9v battery to see which way the cone would pop.

How different is a 7.2S with Bose? I know the PCM to be different. All I want is a speaker, maybe amp, upgrade. But now with all the goodies out there, and my limitations with the PCM in regards to Apple/Android compatibility I'm thinking head unit.....down the line. Camaro' s in for upholstery ($$$) and still have wheel issues...but planning.
