Bose speaker upgrade in 718GTS

[DrG1970]

There are a number of threads on Rennlist about swapping out the Bose tweeters for the Burmester versions. I decided to give it a go… Two new tweeters ordered from the local OPC came in around £130. Some careful use of plastic trim tools and 5-10 minutes per side later the original Bose tweeters were replaced with the new Burmesters. Easy replacement - you just need to remove a tiny section of plastic on the original connectors to allow them to fit into the Burmester speakers. Must say, they are a great upgrade - much clearer sound… for those times when I’m not listening to the flat six singing!

Would you mind sharing any detail of part numbers etc so I don’t stumble at the first hurdle with my OPC? Thanks Tim

Thankyou for that information

 

[MrDemon]

I also did it and added new capittors to be on the safe side.

 

[DrG1970]

No problem.

FWIW I didn’t bother with the caps and I’m listening at decent volume levels - enough to be heard at 70 mph with the hood down. Great simple upgrade, definitely improves the sound quality.

 

[MrDemon]

Do it once do it right I thought.

Have just been quoted £216.60 for the 2 tweeters inc PCGB discount from OPC Reading, think I need to shop elsewhere?

 

[MrDemon]

that would be best I paid £135.

Yes - that’s ridiculous! I paid £65 each… shop around at some other OPCs. They’re not large so postage shouldn’t be too expensive.

 

[MrDemon]

I always use eurospares, 2 left in stock snap them up quick always avoid OPC's where possible.

New Genuine Porsche Part number 7PP035412A, loudspeaker tweeter. (eurospares.co.uk)

Good effort! You’ll need some plastic trim removal tools (and something to rest them on like a chamois, microfibre, etc.) to lever out the air vents. If you’re like me you’ll spend 15 mins removing the first and then 30s on the other side! You can modify the connector cable by removing a tiny section of the connector block using a sharp knife / stanley blade. You can check out the install process (you probably have already!) on the Renn list page: https://rennlist.com/forums/718-gts-4-0-gt4-gt4rs-spyder-25th-anniversary/1289190-bose-tweeter-upgrade-17.html

You’re absolutely right, the shall I, can I, should I and an over cautious 20 mins for the first then 5 mins for the second followed by a reset of the audio parameters and I’m very pleased with the result

Great! Pleased that worked well for you - I think it’s an excellent upgrade for not too high an outlay. Happy motoring / listening!
