Thanks Jeff
I am Meridian- so the Amp is in the back
I am in the same mind that it may not be the speakers
But I have already replaced both head unit and Amp
With no change
So unless there is something else in between AMP and speakers it can only be the wire or the speakers- right ??
oooh - fancy, Meridian :)
I still thought there was an amp under drivers seat though? There certainly is in the earlier models...
Looking at the wiring diagram, the amp cable connector for all the high range speakers is separate from the sub and low range - C0491 for bass, C0492 for the high/mids. High and mid speakers run off the same cable from the amp, and split at the speaker using the crossover mentioned earlier. Is it possible there is corrosion in the amp plug?
I'm not full bottle on the setup you have - are there also headphone jacks in the doors? Could one of these have gotten wet or something else in it, and shorted out, to send the car into a state where it thinks it needs to cut speaker sound in favour of headphones? Maybe plug a headphone into each port if they exist, and free them up?
You don't have an IID tool or similar do you, that could read fault codes from the car?
Thanks Veeb
I don’t think there is “another” amp under the drivers seat but will check
This is driving me mad!!
Update
Pulled the panels off the doors
No surprise all speakers working
Just NO BASS or Mid tones
Circling back to the AMP or head unit
Sigh
This is doing my head in
As I understand it
1. Head unit processes the audio
2. Sends audio digitally via fibre optic to the AMP
3. AMP then de-encodes the data - splits it per channel and pumps it out
So either the AMP is busted or the head unit - BUT as I have replaced both (albeit with 2nd hand gear)
WTF!!! What else could it be?
Have you got the RSE and DVD player? Only ask because that supplies audio to the AMP using SPDIF and not the MOST loop so it'd be a separate source to test with.
I guess the next question is do you have sound coming from each individual speaker? You can use a bit of hose as a stethoscope to listen to each one as you move around the car.
Wish you were in Perth, this would be a fun diagnostic.
Thanks BradC
So do I
No only the head unit
And I put my ear to every speaker- all working
(But no bass or mid tones coming from the big speakers)
Question - I did notice that the MOST (Fibre) is a daisy chain - but I did notice yesterday that …. When I unplugged the MOST connector from the AMP only ONE of the lines was lit
I also remember that when I was replacing the head unit - there was only one lit there as well??
Could the cable be stuffed and that’s why this is all happening ?
Cheers

Strike that
It’s a loop - and have checked by shining lights down cable
Argh!
One line is in aka receive and one line is out aka transmit. The device it’s connecting to will retransmit on the unlit line.Quote:

I have tried to test them but tricky with the plug
I have “listened” to each speaker and each is putting out sound
- but -
the low frequency speakers in each door SEEM to not receiving or putting out the low frequency sound(only the higher frequencies)
I am starting to think that there is a gain issue in the Amp?
And As I have replaced the amp with a wrecker one - it is I suppose possible that the same had happened to THAT amp
Argh this is a pain
