Now thinking about ditching the PCM system and fitting a Kenwood DNX 9180 DABS to work with the Bose speakers.

Is this straightforward or do I need to retain some of the existing components? Can I do this or does it need a specialist?

Got a quote from a car audio specialist today and was a bit surprised that they’re quoting £420 for a fibre optic adaptor to work with a Kenwood unit and existing Bose amp. The other option is a new amp at around £400 but the adaptor won’t be required.

There’s nothing in the Kenwood blurb that says an amp is needed.

Does this sound right?

There doesn't seem to be much point in trying to integrate the Bose amp if you aren't sure it is working.


You can get a cable to connect the speakers directly to a head unit, provided the unit has speaker outputs, of course.  The snag is that Bose speakers are 2 ohm impedance, and most head units (and amps) are designed for 4 ohm speakers.  It would work, but the sound quality might suffer.

I’m going to get the amp checked and maybe it’ll be a cheap repair. Thing is it’s going to cost £400 to integrate this with the new head unit.
