"Well, I have car music again. It doesn't sound great, and I have to manually apply +5VDC to turn on the amp, then disconnect another cable to turn it back off... but it works for now."

In the words of Steve Carell, "I hope you have a big trunk, 'cause I'm puttin' my bike in it!"
More like "flew into the coop," really.
And glued it, and taped it...
