Hi Harry,
We run a pair of Jambox Bluetooth speakers when camped. They fit well in the shelf above the driver side windows and the charge lasts all weekend. 
Nice thing is, they're portable so no theft issues...
I'll never invest in an expense car mount stereo again.
But then again, I live in Oakland...
