Carlos, from your other thread we got confused if you are using aftermarket HU and/or amp.
You described your HU having a CD/DVD behind the screen which X5 never came with.
Are you sure you have the stock sound system?

TerminatorX5, the DSP diagram you've posted is spot on with the connectors that came with the DSP amp I purchased; the amp is the correct version for my production date.

But riddle me this: the factory Hi-Fi system I'm working to replace, the amp harness has six extra wires. I thought perhaps they are for the telephone but I see the DSP connector is accounting for the phone option. I just have business CD above my MID and no NAV. Any suggestions on what those extra wires would be there for? You'd think the DSP amp would require six extra not the other way around.

Just saw this on the phone. I will look closer once on computer

I had a similar situation with my radio unit after a jump start. The whole right side was dead. I sent the unit (I think bm53) to a fellow in the UK named Baris who worked his magic for a lot less than any replacement I could find, even with int'l shipping. Supposedly upgrades the faulty parts in the process. I know he's been referenced here a few times. Company is called Carphonics. All communications were via email and still working great.

i am not on home computer and don't have the resources handy, but if i remember correctly, some audio systems had 10 speakers, and some had 12... I think, some models even got 8 speakers... Even with DSP, you may have the subwoofers in the right rear compartment or, you might not...

I need to pull the wiring diagrams again, and see how the schematics are laid out and what options they show...

it will be much later today or even tomorrow..

I wouldn't buy a new amp until I was sure what the problem is.

Are the tweeters the ones making the noise and all other speakers are silent?

FYI-I have DSP and replaced the speakers amp and sub-woofer with a set from Bavarian Soundwerks. Have had it installed for several years, never a problem. Big improvement over factory system. BSW has sets to work with DSP and have great tech support and directions are easy to follow.
