Had a pair of the DB 651's on my bike, they sound great!....BUT there was one small problem that my friend and myself had with them, there is a small capacitor next to where the wire connects to the speaker, it will break from the vibrations of the bike after time, I re-soldered mine several times and finally gave up and went with a set of Rockford Fosgate Prime R1653 speakers, they are 3 way, the Polk DB's are 2 way. The Fosgates sound much better IMO.
