[s-cars] Bose system pops with Alpine deck

[Eric Phillips]

I hooked it up using the antenna/amp power signal to the amp turn-on
relay J225 (IIRC), just like the two other guys who I know of that
have a Traffic Pro in their UrS cars.  I spent significant cell phone
time talking about the exact harness pinouts, and the implications of
doing one way over another.  Let's just say my continued amp popping
was cause for significant consternation.  :/

Both of those Traffic Pro guys said the very same thing - "It should
work right out of the box."  Those were the exact words, LOL.

Even after doing everything in my power to make sure there was no
ground loop in the sound system anywhere, and still having the
popping, I had to just had to accept the "special" nature of my Bose
set-up.  Short bus "special".

Someday, I will have my revenge on Bose...
