Superheart:
Can't give you any insight as to the performance of the Secret Audio since mine won't be in for a day or two yet. I can, however, tell you that the first cd changer I received didn't work, the second was a refurbished which also didn't work but the third bench tested o.k.
I'll try to let you know how mine works out.
Westchester:
140 watts divided between 4 channels is probably not enough push to be heard over the pipes. I'm adding an amp to my setup to push it up to 60 watts per channel. Even then it may not be enough to be heard over the pipes and wind noise at speed. I wasn't really planning on it being too useful at speed but wanted to be able to use it in city driving.
Again, I'll try to keep posted once mine goes in.
