My recommendation is get a head set, if you want quality sound. When you are buzzing down the street with you system full bore, that is not quality sound. Make about as much sense as surround sound on a bike for quality.
+1. I had some on my bar for awhile. They had decent sound that washed out at higher speeds. Mine were the size of half pound coffee cans and heavy as lead. Check into Kie interphone on eBay. Threse are by far the best bang for the buck IMHO.
