Sounds good until you get too loud and it will start to distort. No problems hearing on the highway. Included volume control is a roller switch that seems to be really loud or too low, but it's still new so it may get less touchy over time. Overall better than I expected for a lot less with accesories than what cycle sounds wants for a lot less wattage. Took several hours to install including getting wires tucked away. The inclued handlebar clamps are very difficult to make work but they finally did.
I just bought this system and it jams its easy to install if you know a little bit about wiring but it sounds great and is loud also distorts a little when turnsed all the way up but overall its a great system. I just wish I could find two additional speakers to match these I cant find them.
