custom audio...what do you have?

I went with Custom Auto Sound cuz it fit the dash bezel without modification. Up side is the USB port, can carry butt loads of music on memory sticks with out people seeing CDs in your car and giving them a reason to break into it. Down side is it needs an amp cuz doesnt have the punch I like. Does sound decent in a parking lot without the engine running. A 4 GB memory stick holds about 50 albums.
