This Bass Booster Port Kit provides significant improvements in bass response without adding a subwoofer, and has no impact on usable Tour-Pak® carrier cargo capacity. When installed, the open port permits the speaker pod to "breathe", reducing the compression effect that limits speaker cone travel.
Fits '06-'13 FLHTCU, FLHTCUTG, FLHTK and FLTRU models. Also fits '06-'11 FLHTCUSE models and other Touring models equipped with King Tour-Pak and Boom! Audio Rear Speaker Pod Kit. '06-'10 FLHTCUSE models require replacement of Original Equipment amplifier. Does not fit with Boom! Audio High Output Sound System P/N 76418-06 or 76418-06A. Dealer Digital Technician software update is required. Dealer installation is recommended.
