I've reparied a lot of these, and the repair cost is under half of the spare part price if outside warranty.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

10 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 1Original post

I've done extensive research on the ASK amplifier used in M490 Sound Package Plus, an option in several Porsche models, and as standard in S models without Bose sound system . Porsche part number is 987.645.331.01 / 997.645.331.01 or other. (9xx.645.331.01) The amps can develop an internal fault caused by a design flaw. The fault can be observed as either no sound at all, (a failing internal power circuit) or abnormal high sound volume on the bass channels. I've reparied a lot of these, and the repair cost is under half of the spare part price if outside warranty. Cheers, Tore

POST 2Original post

Kudos to Tore for figuring out the problem, working up a redesign, and offering a repair service. I recently sent my amp to Tore which took just 21 days for the round trip from Houston, Texas, to Norway and back by International First Class Mail. I'm the second owner of a 2007 base model Boxster with the Sound Package Plus, and for a while just assumed that the system was what it was - not very good. One day I discovered that the fuse for the ASK amplifier was missing from the fuse panel, which made me wonder how there was any sound coming from the speakers at all. Researching this forum I learned that the ASK only drives the bass speakers in the doors, plus the center dash speaker. With the radio turned on I inserted a fuse and for about two seconds heard glorious sound. It then turned to a very loud hum and I quickly pulled the fuse back out. An email to Tore confirmed that this is one of several known failure modes for the ASK. I'm now enjoying the sound system the way it was supposed to be - not bad at all for a roadster - and was motivated to burn some MP3 CD's for long trips. You can contact Tore here: Bergvill FX

POST 3Original post

Thanks for the post I have the same fault. Glad to know I am not alone and it is a known fault

POST 4Original post

I have one of these amplifiers, removed from my 2007 Cayman S if anyone is interested - $100.

Tore is apparently still doing the repairs. Here is the Porsche amp page on his website: Audio amplifiers - BERGVILL F/X

POST 9Original post

Hi Tore I bacame crazy with this sheety porsche sound system I have no bass at all on the car just medium and tweeters i change the amplifier not new and same issue is this the design of the amplifier I've heard cahnging the relay but nothing to do im sure this issue comes from the amplifier i have around 6v on all the out pin on the amplifier except the 12v,ground and 2 not connected pin and 2,54v on two pins Thnaks for your advise

POST 10Original post

I just got my repaired amp back from Tore, and it works perfectly. I really appreciated finding this thread, so thanks to the also for starting this years back. At some point I'll post some pics of the amp removal process--not that it is hard, but a few images would likely help the clueless like me to get the job done quicker
