I have a CDR2006 in my Omega and there is an intermittent fault - it cuts out every few minutes, and then cuts back in again.  I have tried a different head unit but with teh same problem so think it must be somewhere else.

I think I read somewhere on the forum that there is a separate amplifier in the circuit - did I imagine this?
If there is then where is it located as it seems to be a common link that may be where the fault is....

Only Elites came with the seperate Bose amp as standard.  To check, in the boot, right hand little cubby hole, see if there is an amp in there.

What cuts out? Audio? or Power?

Tried wiggling the voloume button?

Tried re-seating it in the cage?

Its the audio that cuts out. The main display still shows the station tuned into.  It cuts out on tape, cd and radio.

Hmmm, sounds like amp protecting itself.  Wonder if a speaker is on its last legs  :-/

I am watching this with interest as I have a 96 Elite with a SC 804 CD which has the same problem. Started out as an intermittent fault but now with no audio. Is the amplifier under the parcel shelf for the aerial only or is it audio?

You may have a philips amp just in front of the spare well - have a gander there

[Dave DND]

Does it work on really quiet volume and then cut out as audio increased?

That would indeed be a sign of a speaker on its last legs.

Also worth disconnecting speakers in turn to see if audio is restored

I'm going to keep an eye on this as well...I have a 95 elite and the set up in mine is not the bose but all aftermarket stuff and mine is doing the same thing ?? has been for a few weeks now and i still have yet to cfind the cause ?

[A380 Elite]

I too will keep an eye on this,
How important is the cage the radio sit's in? As mine bends like anything.
Radio station’s work when they want to.
This I found to be the areal connection, if I hold it out, it works fine, fit home, nothing.

Thanks to all for the input.
First a correction - it is a CCR2006 (not CDR as I put).

There is no amp in the cubby hole or in front of the spare wheel, so unless there is something mounted under the car or inside the dashboard there probably isn't a Bose amp unit anywhere, so why would it say 'Bose' when switching on?

It cuts out whatever volume it is playinjg at, and doesn't matter if it starts low or not.  It may be linked to bumps on the road, but has also cut out when parked. 

Usually when it cuts back in it does so at the same volume but has on occasions come back on with full volume (which is scary if driving!).

I should have a chance to pull it out tomorrow (any suggestions how as it is very tight - I tried at the weekend with the usual pullers and it wouldn't budge) and look for external bad connections/breaks in the wiring.  My logic says it won't be teh power lead as the display remains when it cuts out, so it must be transmitting a signal, which needs power - correct? 

That leaves the aerial socket, as the speaker wires would not affect every speaker at once.

Would it be possible for a 'mute' signal to be cutting in (say for the phone, which isn't fitted)?  Otherwise I guess it is the unit itself that is sick.

If not a bad connector at the rear of the head unit, try disconnecting each of the speakers in turn, as a short circuit speaker under load (very common) can put teh unit into protection and shut down the audio.

[colin33]

I have remove dthe unit and checked the connections into the cage and the radio unit and they all look OK. Put it back together and the fault remains - again sometimes it cuts in at full volume, somethimes at the original level.

I have not yet checked the wiring to the back of the cage (I assume I take the glove box out to access these, or am I better taking the cage out instead?).

To disconnect the speakers at the speaker end - how do the door trims come off?  Is it easier to work at the head end instead?

Colin

[Dave DND]

Due to limited space behind the head unit, probably easier to pull the door cards off

Door card removal is covered very well here:-
