The noises when opening the door (ignition off and key not in the ignition) would make me suspect an amplifier issue as well.

Suggestion

Most of the times when it does turn on is if the car is already warmed up or driven in the past few hours like if I run an errand at lunch time after driving the car to work in the morning.

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.

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

POST 1Original post

I have an 06 Boxster S with the PCM2.1 and Bose sound and most days when I start my car, I get no sound. No radio, no CD. The PCM always turns on, just no sound. Most of the times when it does turn on is if the car is already warmed up or driven in the past few hours like if I run an errand at lunch time after driving the car to work in the morning. Very rarely though it will come on when I start the car in the morning to drive to work. I "suspect" it's an amplifier issue but who knows? Another possibly unrelated issue/symptom is when I open the drivers door to get in (before the car is started) I sometimes notice the speakers will pop or hiss. Cheers, Julian

POST 2Original post

Have you physically looked at the amplifier? The noises when opening the door (ignition off and key not in the ignition) would make me suspect an amplifier issue as well. The first thing I'd do is track it down and make certain it hasn't experienced any water intrusion.

POST 3Original post

went out and had a look at lunchtime, looks perfectly clean (I'm presuming there's only the one amplifier, its a black one behind the toolkit cover) I unplugged the 3 plugs and there wasn't any sign of corrosion or dirt. I'll try removing it this weekend so I can inspect the insides.

POST 4Original post

Ive had this happen as well several times. I read on many many forum posts it comes down to, three issues #1, The bose amp is going out #2, The battery is going out or #3, Hot from a lot of use. I found my battery terminals were so loose i could pull them off and its now fixed, My battery is 1 1/2 years old. You want to try the Bose amp its under the seat and its pretty cheap on Ebay for around $90-$140 Used. I know a guy here that had the same issue and he got a Bose amp (Ebay) for $110,00 and he has had zero issues since.

POST 8Original post

I would suggest thats a difference between 987 and 981 . I presume you don't have one in the frunk too? Julian
