BOSE Schematics DENSO Schematics

Hi Guys,
I Have a 2002 Cadillac Seville with the Bose Premium system installed and DENSO Head unit.

Could anyone help with a Source for schematics & or repair on these?

Let me guess, the speakers are hissing and crackling.

Remove the bose amp and rebuild it with new capacitors.
If your lucky the old caps won't have been leaking for long and won't have damadged other ic's.

As for getting diagrams for the bose amp, forget it.
Unless you work for bose or the actual manufacturer your chances of getting any info is next to zero..

Hi,
Nope the Amp is working ok, I am not happy with EQ curve in the car and I would like to alter it. (assuming it's not done using a serial bus)
the amp is the Bose UX9 option.

Really ?! It's working, well I'll be.

I'm not familiar with the car (well der, I'm from another country).

So I can only go on what I have seen/worked on.
(corvette/camaro/mercedes)
The amps have active crossovers built in and could only be changed by component replacement.

As for any eq filtering, sorry, your on your own.

I have seen an 'interceptor' made by I think it's audio control.
It allows you to feed the headunit signal into it and then do correction, adjustment before it gets sent to whatever amps.

Just had a quick search, maybe something like this

Thats the one I was thinking off.

Oh well, hopefully the RF will suffice.

Only complaint I'd have with it is the sub xover needs to go lower.
I mean 50Hz, pft come on, I'm running a single 8" at 40Hz xover.

If I have helped then I am happy.......

EDIT, Speeling mistooks......
