Harley 10 Inch Subwoofer + Saddlebag Installation Kit Part# RAZOR10


Featuring the all new Velocity RZ10. The Velocity RZ10 subwoofer is an all new type of speaker that has been designed specifically for performance in a Harley saddlebag. These subwoofers have a much lower moving mass than a normal 10 inch subwoofer. The lower moving mass together with tuned suspension allow for the woofer cone to stay under control even at extreme volume levels with a saddlebag as the enclosure. This amounts to much higher volume levels.

What You Get

  • 10 Inch Velocity Subwoofer
  • CNC Machined HDPE Subwoofer Mounting System
  • Stamped Steel Subwoofer Grill
  • Specialized Router Bit
  • Router Template
  • Extensive Neoprene Gasketing
  • All Stainless Steel Hardware

Frequency Response Tailored for Harley Sound Systems

Velocity subwoofer systems are designed to work in conjunction with other smaller speakers on the bike for a much bigger bolder sound over all rather than an exaggerated bass that you would expect from a car audio system. Designed specifically to compliment and keep up with extreme level Harley sound systems, these subwoofers have the ability to keep up with compression horn drivers for hours on end whereas a car audio or marine type subwoofer would go up in smoke attempting to do the same thing. 

2 Ohm Voice Coil for More Output

Velocity RZ10 subwoofers feature a 2 ohm configuration that allows you to squeeze twice the power from your amplifier as compared to a 4 ohm subwoofer. This is a huge advantage in Harley audio systems since amplifier space is always a concern. 

Fitment: Harley Street Glide, Road Glide, Road King, Electra Glide, Ultra 1998 through 2021. Hard saddlebags only. Will not work with soft bags or switchback bags. See full installation instructions for more details here.
