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

No point me writing a book . . Who ever listens to what I write anyway !!

looks cheap enough to have a play with 

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.

I don't know if this is at all relevant to the Omega/Bose combination but one way of getting maximum output from an audio system running from a restricted (ie 12volt) power supply is to use a pair of amplifiers to drive each speaker in a bridge formation http://en.wikipedia.org/wiki/Bridged_and_paralleled_amplifiers.

If the Bose amplifier is expecting one wire of each input to be ground and the other to be signal it might get very upset if the 'ground' wire is being driven.

Maybe the Bose setting in Tech 2 turns off one half of the output bridge in a CCR2006  :-/

To throw some more fuel on the BOSE / OMEGA bonfire.... What would be better from my point of view would be to keep the NCDC head unit (so everything looks standard to an outsider and the Nav / board computer) but replace the Bose amp and speakers with something of a little higher quality. I know in the chain of Hi-Fi seperates the argument is always to buy the best source units you can and then build outwards from them but it'd be interesting to see what the NCDC units are capable of when coupled to a half decent amp and speakers in a similar way to Kevins modification to a CCR2006.

If I had a car without an NCDC in it to start with I would certainly go down the complete replacement system route

Could have given you a demo at the weekend.

You are correct about going for the best source unit you can, but never overlook the speakers either.

The range of Clarion speakers we have on our website appear to be just about perfect for running with OEM head units and can give a significant improvement in sound for those of you wishing to retain the original appearance and functionality - I`m all for that -

But change the bits you can`t see - like the speakers !!!

 

[Shallow Al]

 Can you say which Clarion speakers will go well with a CCR2006, non Bose, that you stock please Dave.
 I am reasonably happy with the sound of it, but would new speakers help it to 'Go up to 11'
 Cheers

[Dave DND]

What size speakers are you after ?

Have a look in or website at the Clarion SRQ and SRE range

These are ideal for any of the Non BOSE OEM vauxhall stereos

Most popular are these

The fact that theres no screened cable connecting the HU to the Bose amp would suggest to me that the amp input is floating earth, ie, balanced input, so along them lines it would make sense just to lower the speaker level from the HU.

From what I've deduced from the innards of the CCR2006  it's still the bridged power amplifier ICs in the 2006 that drive the Bose outputs exactly as if they were still speaker outputs so yes, it's almost certainly a balanced input to the bose amp.

Makes sense then Kevin, considering the amps at the back of the Car, a balanced line would give better s/n and line loss compared to a unbalanced link plus it makes it easlier for Bose to just reduce the level.

Have you taken a Bose amp appart yet or played with one?

Chris.

[harpersimon]

Just read this, and wanted to change my head unit on my elite to something with Blutooth etc etc..
but being new, and don't shoot me - are we saying that as I have Bose (cos its written on the rear shelf speakers) I cannot add any other head unit, and would need to change everything?
bugger.

Correct. Everything has to go...

[harpersimon]

Double bugger. Oh well saved me wasting a couple hundred on a unit I was about to buy, but made it more expensive to change anything. Think I will be leaving it all be then :-(

Nope. Never personally had the need to. If anyone's got a spare lying around I'd be happy to do some research though.
