hi All,
         got a list of to do.s on the " new to me "  '53plate  3.2 Elite .But heres the first enquiry .   The Bose system does not seem to sound anything like the Bose's I have had in 3 previous Omegas.  I have tuned it ( Bass-treble -balance -fader etc.) & it sounds better than how it was set. but still very dissapointing . Sounds very bass heavy even with bass cut to almost nothing   or maybe it's treble sparkle missing , treble is almost on full. Front tweeters seem to be working but maybe not as they should.
Was thinking maybe knackerd speakers  , "muddy" would be a way of summing it up . Any pointers or ideas please ?
TIA . . . . Al

The Bose enabled head end has a setting in Tech2 to tell it whether it is driving normal speakers or a Bose amplifier. The Bose setting applies an equalisation curve that is unique to Bose.

I wonder if yours needs to be changed?

It;s a 2013 head  Andy  . . .if that makes any difference

They weren't all Bose though were they?
Probably says Bose though on the screen on start up?
I have a couple of spare tweeters you could try if you find they may be the problem

yep  Bose on display,    Bose on rear shelf speakers . . .  but sound is just about on par with the non bose 2006 system in the MV6

As far as I know the Bose on  the Display are Tech 2'ed on the Display itself and dont show any reference as to whether the NCDC HU is Bose flavour or not, as Andy H says could be its been messed with by someone. Having said that a non Bose HU in a Bose set up would give a All or nothing range on the volume control followed by heavy distortion as the wick is turned up.

As far as the Tweeters are concerned, in my opinion there probably the last things to blow, as there low level Power driven compared to the rest of the other speaker set up and in a way are protected by its own crossover network, namely a capacitor in series and a coil in parallel which will reject any high level Bass or mid range frequency voltage. Having said that the Tweeters in a Bose set up are standard VX ones and are the same as normal non Bose ones, so easy enough to swap out in case they are water or physically damaged.

Unlike your MV6 the Bose is an Active system, so each speaker range is driven by an separate Amp Module within the Bose Amp. So I would start with the basic's, checking the Amp is there and the connections to the Amp and the foot-well connections are good.

If it helps Al, I need to be down at Basildon Hospital at some point and am quiet happy to meet up, have a liston and give a second opinion.

Hi Chris,
             right . . .   Bose amp is there sitting under the rear shelf in a black plastic casing. The sound does distort quite quickly one you start to crank it up though .
As said  sound seems very bottom heavy & lacking sparkle.
Plan to have wheels off for refurbing  amongst other jobs to be done , so sadly  a meet up at Basildon unlikely in the immediate future

Might be worth wiping the door cards off to check the speakers.

I think the Tech2 setting to display 'BOSE' is independent of the setting to change the output levels.

Sounds like a non-Bose'd head unit to me.

If thats the case  . . . is it just changed  with a Tech 2 ?     Excuse my ignorance but clueless on this subject

Yes it can be checked or changed via Tech 2 but your need a Car Pass for the HU.

got the original VX car pass is that what you mean ?

Tep,

Assuming thats what the problem is, which it well could be. On the Bose System, listening to a Middle of the Range' CD you can pretty much turn the wick up full blast with very little Bottoming or Distortion, if you getting early distortion or loud levels at low volume position level (use the steering wheel function if it helps as the Vol Knob on the HU just spins), then that would susest that the HU is kicking out higher o/p levels than it should, ie, non Bose configured.

It seems to be distorting quite early in the volume range. Had bose in 3 other omegas & never had to have the bass anywhere minimum.  Whats worrying me is though if the HU was changed  it would have different car pass details would it not ?
