So I ended up getting an Alpine ILX-207 ( it is what I really wanted).. Now I need to sell my W960 once I get the ILX installed

yea, they are heavy and cost a bundle to ship!!!

Should be worth $175 - $200 or so. They are $270 new.

I finally got around to putting a scope on these things.

Based on what I've read here about using the Bose CDM output into aftermarket amps, as well as the difference I can hear between the two, I was expecting to see some ugly equalization in the Bose CDM.

This is what I found

600) this.width=600" />

600) this.width=600" />

600) this.width=600" />

600) this.width=600" />

('MaxV' is at the highest voume setting that doesn't clip. For Bose this is at 100% volume. For non-Bose at about 75%. 'LowV' is a lower volume setting, around 50% of MaxV. All are with tone controls at neutral.)

So, based on frequency response, the Bose is a much better signal source.

However, I also found that the signal out of my non-Bose CDM is perfectly clean, while the signal from my Bose CDM is an ugly mofo. I see both periodic amplitude variance (with low frequency input tones it looks like an AM signal) and also a settling of the amplitude over time.

Based on this, I have to assume that my Bose CDM is bad, but on the other hand, since people have reported since the beginning of time that the signal out of the Bose CDM is crap, and since it clearly isn't the frequency response, maybe what I'm seeing is the problem.

If anybody has a Bose CDM they don't need I'd be interested in checking another one to see if it performs the same as mine.

There are some interesting control quirks with the Bose CDM. When you turn the bass control up, it cuts the mid frequencies. With the knob up all the way it boosts 30Hz by 30% and cuts 1kHz by 30%. The non-Bose behaves in a normal fashion, just boosting low frequencies.

The other quirk is with the fader. With the Bose CDM, fading 100% to one direction only reduces the opposing volume about 50% (a WAG from listening - didn't actually measure this). With the non-Bose CDM you get the more normal behavior of turning off one set of speakers when the control is in an extreme position.

I like the spec... and if its like my current Kenwood, it's should sounds great.

Oh, Crutchfield now sells Morel speakers.

I assume there is a problem with the current antenna?

If you went generic aftermarket, it will still work, the antenna was made by Hirada, IIRC, for GM.

The thing is, there is a harness at the antenna that has all you need.

Remove the LR tire.

Remove the inner fender.

Contort yourself into a pretzel and remove the bolts that hold the antenna to the chassis.

There is a special socket that GM sells to remove the crown bolt that holds the top of the antenna in... It's thin... should be able to find one somewhere. They come with a mast replacement kit or a new GM antenna. I had two, gave one to a friend, lost the other... damnit.

The wire at the harness should be pink.

Check the attached file. It has a PDF in it that has the FSM sections on the wiring diagram from the various components.
