Bose Crackle

[Sir WIll]

Ladies and Gents,

On the ongoing OCD search for perfection with the D3 I have noticed that there is a "Crackle" coming from the front dash speaker.

Done some work into this and I think it may be the amp but would welcome any feedback if anyone has had any experience with this in the past.

Points to note:

1) CD and Radio both crackle
2) No matter what the music source it crackles
3) This is not cooked or rubbing voice coils on speakers
4) There is no intermittent sounds or breakup
5) Volume and power all OK and no distortion
6) This does not sound like driver distortion

The crackle to me sounds like its not being processed correctly or perhaps an Amp being a little upset hence why I am thinking Bose

Have you tried fiddling the Bose sound settings?

[Sir WIll]

Not touched them, its a valid point as the processing could be the problem.

I shall have a play and see, plus ensure "Crackle" is turned off

IIRC Ian had some problems with the centre speaker, its dead easy to replace it and that would be where I would start. Replacement speaker should be easy to source from a8parts.

Thanks but this is not speaker rattle or distortion here, it's electrical amplification or processing.

I may take out the amp and check the boards.

On other makes of car with BOSE, I have read on forums several times this attributed to dry joints within the DSP/amp.

Agreed, that's my thinking on this now also after some Google homework.

May have a look over the bank holiday weekend!
