Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
The problem is as stated in the title - When you have the bass turned up above anything but -6 (the lowest setting), you get sounds of distortion from the speakers, specifically regarding bass.

Since the distortion happens regardless of how high or low the volume is set, I'm starting to think this is an issue with the head unit or the amplifiers.

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.

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

POST 1Original post

Hello everyone, I recently purchased a 2009 Cayman with 18k miles, and I'm having an issue with the sound system. The car is lightly optioned, and that includes only having the base, 4 speaker (really more like 2 channel) setup. The problem is as stated in the title - When you have the bass turned up above anything but -6 (the lowest setting), you get sounds of distortion from the speakers, specifically regarding bass. Initially I thought the high pass filter on the tweeters had failed, and all the bass going to them had blown them. Upon further inspection the tweeters are working just fine, and the distortion also comes from the door speakers. Since the distortion happens regardless of how high or low the volume is set, I'm starting to think this is an issue with the head unit or the amplifiers. There's troves of information on here regarding the SPP and Bose systems, but next to none on the base sound system from what I can see. What I have been able to find about the system was from an old German brochure I have, which says the base sound system has two amps, putting 25 watts out each. My questions are: 1 - What could be causing the sound issues? 2 - Where are these amps? Because they're not in the frunk. 3 - In the event that this is a head unit issue, has anyone gone through with *rebuilding* one of these? I'd like to keep the car looking stock, and that includes the HU. Not a fan of aftermarket looks. Thanks!
