I think you’d need to replace all speakers to really make a difference.

Coverage and how to read this overview

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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Ok just bought this car and the sound is bloody awful. First point of call for me is to upgrade the tweeters i'm following this thread fitting Dayton Audio Tweeters. https://rennlist.com/forums/audio-and-video-forum/... However im looking for advice on the door speakers next. Im unfortunate to have the Sound package Plus. Any pointers appreciated.

POST 2Original post

I think it's easier to upgrade non-bose sytems actually. I have bought the recommended Audison 8p woofers for the doors, Focal 4" components with tweeters. I was about to buy an Audison 5ch amp and DSP (which I need with BOSE) but i'm chopping the car in now so all redundant! Hoping the speakers fit in the new car.

POST 3 / ORIGINAL POSTEROriginal post

OK Nice did you fit them yourself, do they go in the existing mounts without mods? Did you add some sound insulation to the panels in the door too?

POST 6Original post

I did the tweeter upgrade. The clips are a complete b@gger but once you realise how to do the second one is easy. It did make a difference but up to speed the overall sound is still pretty poor and is not at all night and day. I think you’d need to replace all speakers to really make a difference. The 911 is a noisy car so always going to be difficult. I now have a GT4 and the sound system is so much better standard thank god.

Have you still got your car or gave you already p/xd it?

POST 8Original post

I just did a stage 1 at Audiofile Incar who I can highly recommend. The stage 1 is sound deadening on doors and focal 4 inch in the door and focal tweeters. Noticeable step up in quality of sound however it does highlight weak (Bose) woofers so I’m now thinking about going back for woofers and amp upgrade.
