Set up this today on my son's 82 Honda GL500. The hottest model comes with bar mounts rather than the previously noted reflection mounts. I would personally have given this system a 5 star if designed for the speaker mounts and the wiring at the fuse housing was frayed. The mounts require at least 4 hands to assembly with ease. Carrying out it from your self is a pain in the butt. not a great design on the brackets. I removed the join housing and about 2 ft. of extra line from the +/- interconnection as the bike acquired a spare inline join I was able to use. Amp installed under seat nicely as the unit was smaller than expected. If designed for the speaker mounts and frayed wire, I would have given it a 5 star.
