Can I replace a faulty Bose CCR 2006 with a CDR 2005 or do you have the same problems with the ohms of the speakers?

TIA

[Kevin Wood]

If the car has a Bose system then the 2005 will need to be coded for Bose using a Tech 2, if it's possible for that model of Head Unit. :-/

Otherwise, the whole Bose setup needs to be replaced with non-Bose.

cdr2005 does not have a Bose config.

However, it can be fitted with a bose amp, but the volume is fairly uncontrollable at low volume, the tone is slightly off (tweakable with normal bass/treble), distortion at high volume.

I have seen a few like this, due to ccr2006 being a heap of junk (not as bad as cdr2005 though ), and it can work. HOWEVER, you are running outside of its capabilities, and you are running closer to the point of it tuning into channel smoke....

I guess you could attenuate the signal between head unit and Bose amp to give you normal volume control. :-/ Be a bodge though.

Not really, its not just a lower voltage signal thats needed, its a narrower range from low to high.

BOSE equipment only works with BOSE equipment

In what respect? Are you saying they compress the dynamic range of the signal?  :-/

Think Dave means the Headroom (right levels out to the right levels in, at a given impedance), but having said that, cant see why you cant attenuate the o/p of the HU to a given level and then match the i/p impedance of the amp, assuming you know what they should be.  :-/

[Dave DND]

OK, without getting too technical, imagine  a volume control with numbers from 0 to 10 on it.

O is the lowest volume and 10 is the max volume.
this is what a "normal" head unit gives out.

A bose head unit using the same control would be say 3 to 7  where 3 is the lowest volume and 7 is the max volume.

A non BOSE head unit if connected to a BOSE amp will give no volume when used from 0 to 3
and between 3 and 7 will give no smooth control over the volume
and from 7 to 10 will probably cause it to go bang as it is now being overdriven.

I'm listening. I have no intention of ever owning any Bose equipment let alone mixing it with anything else. I just want to understand what's special about what appears at first glance to be a straightforward audio interface from head unit to amp.

Maybe one day I'll chuck a test CD in my CCR2006, set it to Bose and see what comes out of the speaker outs.

There is a Porsche / BOSE interface allowing the use of an aftermarket stereo in a 996, that on the face of it "should" work on the Omega, but I am not aware of anyone who has tried it yet.

Dave, chill man, your gonna burst a blood vessel, its only 11 o'clock, what you going to be like after England Match this afternoon.

Well, that cant have anything more than a few R's in it.

I suppose that the bose amp could expect a Linearly controlled amplitude feed where as a standard speaker out is Log.

Yep, thats along the lines of the thing I was looking at - Although Audi units are generally different levels to Porsche (but only "Anoraks" would tell the difference in quality), this BOSE adaptor may actually work as a good compromise - and certainly worth a try, as could solve a real headache in "Oof Land".

Drunk probably !!  But not watching the footie though, there is a high tide at around 4pm, a bucket full of bait, and the beach is a mere 400 yards away on a blisteringly hot sunny afternoon, and as nobody else appears to be working either, I do have a dilemma . . .

A spot of Fishing?, or being Billy No Mates sat here answering yet another boring question about BOSE compatabilities.

Maybe you should write a book on it,.............. about the fishing I mean.
