Do you enjoy hitting the road on your motorcycle but are tired of not enjoying your music because you can't hear it when riding? The Rockford Fosgate TMS series of motorcycle speakers solve that problem. The TMS57 full range coaxial speaker is designed to replace existing 5"x7" speakers in factory equipped Harley-Davidson® "Boom!™ Audio" and "Boom!™ Audio Stage-I" bag lids. NOTE: This is NOT compatible with "Boom!™ Audio Stage-II" systems, nor do we recommend modifying the speaker to fit on Stage-II systems. See Compatibility Tab for complete motorcycle fit guide.

Boom!™ is a trademark and Harley-Davidson® are registered trademarks of H-D U.S.A., LLC.
