Product Descriptions

Rockford Fosgate HD14U-STG2 2014+ Harley-Davidson Ultra Stage-2 Kit (Gen-3)

Motorcycle enthusiasts are always on the lookout for the latest and greatest in performance upgrades for their bikes like the HD14U-STG2 M5 audio kit, designed to provide riders with the best in-class on-bike audio experience. The M5 audio kits are engineered to be the loudest and clearest audio systems, featuring simple plug-and-play installation, and paired with freeway speed output, ensuring that you enjoy your ride with high-quality audio.

Plug-and-Play Design for Easy Installation

The M5 audio kit is designed to work right out of the box, with everything included to make for easy installation, ensuring less time in the garage and more time out riding. The kit features a plug-and-play design that requires no drilling or cutting. The kits bolt to factory attachment points, and direct connect wiring harnesses for Harley-Davidson® models are included.

Full Throttle Output for Superior Audio Experience

The audio is engineered to perform on the open road, with speakers and amplifiers specifically tuned and designed to not only overcome wind, road, and exhaust noise but also to give you that second-to-none audio experience on your bike. The HD14U-STG2 audio kit offers full-throttle output, making it perfect for long road trips and cross-country adventures.

RF3 (Rockford Factory Fit and Finish) for a Seamless Integration

The M5 audio kit is designed and engineered to match and complement the factory fit and finish of your bike. These components are purpose-built to exact specifications, ensuring the best-in-class fitment and look. The RF3 (Rockford Factory Fit and Finish) technology ensures that your kit blends in seamlessly with your bike's original design, enhancing its visual appeal.

Element Ready™ for Durability and Longevity

The HD14U-STG2 audio kit is purpose-built for the harsh motorcycle environment. The speakers and amplifier are designed to stand up to water, dirt, UV, and motorcycle vibration, ensuring that your audio system will stand the test of time. Element Ready™ technology ensures that the kit is durable and long-lasting, giving you the best value for your investment.

Features and Benefits of M5 Audio Kits at a Glance

The M5 audio kit includes the TMS65: 6.5" 2-way Element Ready™ speaker with an integrated phase-aligned 25 mm tweeter, M5-800X4: 800-watt 4-channel IPX6 Element Ready™ amplifier, and RFK-HD14M5: Amp install kit for M5-800X4 on 2014+ Harley-Davidson® models. The kit comes with Y-adaptors that support expansion of lower fairing, saddlebag, or Tour-Pak® speakers. The T-harness integration supports front/rear fader control (requires "Rockford Fosgate 2014+ All Bikes" flash). The T-harness features loop-thru for Digital Signal Processor (DSR1 sold separately), and a 90-degree harness included with amp install kit for Road Glide® installations. The factory Harley-Davidson® radio must be flashed to use this kit.

Quality and Performance Guaranteed

The HD14U-STG2 audio kits are quality and performance tested using proprietary RATS (Rockford Automated Testing System). The Klippel Verified certification program delivers the best possible loudspeakers. The M5 audio kits come with a 2-year warranty, ensuring that you can enjoy high-quality audio on your bike for years to come.
