Don't have a Crossfire but sat in one today at the dealership and listened to the radio (boy was i suprised when it turned on without the keys in the ignition). It sounded pretty good. Nice solid feel to it with the base at +9, not slouchy or too boomy, nice and tight . Now I just gotta make enough money to get myself one It's interesting btw how you can turn the fan on when the cars off? Nice feature for those ppl always waiting with the car off... keeps u cool in the summer!
