Hi.
I am currently moving the full bose system from a breakers Omega Elite to my own Omega.
I have successfully fitted the amp in the boot, the parcel shelf 6x9's and plumbed the wiring correctly to the connection point behind the trim next to the accelerator. I have also fitted the other 4 door speakers.
Now. I do not want to take the whole dash to pieces on both cars to remove and refit the wiring loom from the breakers omega and fit to mine. Unfortunately the plugs on the back of the radio's are different as my omega had the CCRT700 with built in phone.
So my question is that can someone help me decipher the attached wiring diagrams to decide which wire goes where if I cut all the wires and re-solder the whole lot?
Any help would be amazing as I currently have no sound system at all :( lol

easier way is to get your arse to Kevin Wood, and get him to tech2 your ccrt700 to bose config. that would save a significant rewiring job ;)
-
how much does that cost and where would I have to go? I'd rather spend longer rewiring if it meant it cost me nothing.

Ta O,
Kev is in Alton.
Do you have the display for CCR800, as your old CCRT700 uses an incompatible display.
The wiring is certainly possible, but its not easy working in the space, and you need to heatshrink every connection (tape is no good in this case) - I'd be inclined to buy a TM loom, and modify that that modify car loom.
Obviously, with ccr800 you lose the phone functionality.
-
Is the car loom the same and just the display different between the 2?

No, the car loom is different - there are extra wires to run between radio and screen as well.
-
Ok thanks. Will contact Kev soon. Just noticed that one of the front door speakers is not a bose 2 ohm but rather a standard vauxhall 4 ohm one so will need a spare 2 ohm bose from somewhere.
I think i will see about changing the ccrt700 to bose settings.
Cheers TB

Hi all again.
I have now got the car programmed by Kevin Wood. So a big thumbs up to him... i even got tea as well :y
Only problem is that no sound is coming out of the system. It loads up perfectly but no sound.
I have simply plugged the bose loom into accelerator pedal connection.

Now the CD player receives all the correct signals and loads the correct cd etc.
The power is being received by amp but no signal down the red&white wire is getting there.
You will see why on the picture above. The top right red&white cable connects to nothing.
Does anyone know how the wiring works, and can tell me what to wire where?
I need my stereo as i can't listen to the new muse cd in the car :( lol
Ta,
-
dont forget to insert fuse 6 in your fuse box - it powers the Bose amp!
;)
-
Kevin and I checked that last week. There is a fuse in that point, and we checked the power was being received by the amp.
-
Just wasted another 2 hours. Really don't know what is going on to stop this thing working. Theboy seemed to thing it should just plug in and play... is that correct?
Would the fact that nothing is plugged into the tweeter cables in the rear door be a reason for no sound?
-

it should be. is the amp powering on?
-
I think the problem is lack of a switching signal for the Bose amp. This is the red/white wire.
We checked that the CD player gets such a signal, and it's clearly getting to the MID and steering wheel controls as these are controlled by the head unit.
Now, you say the red/white wire doesn't go anywhere? Is this a loose end of wire, or just that it goes to the wrong pin on the Bose plug? Could do with a photo zoomed out a little to see where everything goes.
If it's the wrong pin can you pill out the pin and move to the correct recess in the connector?
Failing that I would try to connect the red/white to the bose amp to the red/white that goes back to the CD player or the wire that feeds the antenna preamp as they are all the same signal IIRC.

I have checked that power is arriving at the amp unit so it seems as Kevin says that nothing is telling the amp to work. Or if there is a short on a speaker wire somewhere it could fail-safe the radio... and if nothing is coming out the radio then nothing will come out of the amp.
Kev. This evening I ran a separate wire from the antenna control on back of radio unit to the red/white
cable on back of amp with no luck. Couldn't get a reading on the volt meter either.
So not sure what the problem is.

Might be on to something there - seem to recall that ccr etc use a single wire for remote switch on, whereas ccrt uses 2 (or vice versa)
-
My bose amp just used the Red/White wire as its remote switch
The BOSE amp isnt clever enough to Fail Safe itself if theres a shorted speaker it still works :y
i also used a CCRT700
-
The red/white shown @ the end is for the CD changer, I've just looked @ the loom from a car without Bose and that wire is there.
Most odd
-
ok. thanks for those updates.
So were saying that if i hotwire the red/white cable in the back of the cd player to the amp red/white cable then we may get somewhere?
sorry for delay... im recovering from the piggy flu :)
