Hey Lucky,
I have an 01 road king and I purchased and installed a handlebar system from HD. It's the boom audio system with 3" speakers and amp, it comes with the bar mount control, amp and iPod plug in for $400. I looked at several different ones and for the price it's excellent quality sound at high speed. Cycle sounds.com has a comparable product but it's more expensive so I went with the HD brand. They have a handle bar mount and a windshield mount system, anyway hope this helps.
