J & M 400 W 4-Channel Amplifier/Speaker Kit -'16-'23 FLTRU/FLTRK RKT6-400HR16-UL4

If you're running factory speakers on your '16-'23 FLTRU or FLTRK, you're leaving serious sound quality and power on the table. This J&M 400W amplifier and speaker kit delivers clean, high-output audio that cuts through road noise without compromising reliability or ease of installation. Everything is engineered specifically for Harley-Davidson fairing integration—plug-and-play harnesses, factory-pattern fitment, and stainless steel mounting brackets that secure solidly with zero guesswork.

The ROKKER speakers use lightweight woven-fiber cones with neodymium magnet structures and integrated tweeters for transparent midrange and crisp highs. The full-range Class D amplifier provides 100W RMS per channel into 2 or 4 ohm loads, so you get genuine power output, not inflated peak numbers. Installation is straightforward for anyone comfortable with basic electrical work, and the kit maintains full compatibility with popular factory head units.
