CDR 24 Bose Subwoofer

Recommended Posts

I recently bought an '05 Boxster S with the CDR24 head unit and the Bose sound upgrade. Shortly after taking delivery I noticed that there were no low frequencies being emitted from the subwoofer mounted between the seats.

I took the car back to the dealership (well, it went back on a flatbed truck after blowing a water pump in the first week of ownership... fortunately under warranty) and they advised me that the subwoofer level had just been turned right down and this had now been remedied.

Unfortunately the same has now happened again but I can't seem to adjust the subwoofer level myself. The "bass" adjustment through the sound menu seems to simply alter the front speakers and not the subwoofer.

If anyone has any idea how to change the level, that would be a great help!

Same issue with a 2008 Boxster with CDR24 + Bose sound. It seems like all the bass is coming from the front speakers only, nothing from the large openings between the seats that I assume are connected to the subwoofer. It they aren't, what is their purpose? . Just curious.
