If there were a car audio brand synonymous with motorcycle audio upgrades for Harley-Davidson Road Glide and Street Glide motorcycles, it would be Rockford Fosgate. Their upgrade kits are the benchmark for improving the audio on these touring bikes. With the introduction of new fairing and saddlebags on 2024 and later bikes, Rockford Fosgate has introduced new audio upgrade kits featuring a unique amplifier solution. Let’s check out the HD24-STG2 and HD24-STG3 audio kits for the 2024 and up bikes.
Rockford Fosgate HD24-STG2 Features
The HD24-STG2 is a high-performance two-speaker amplified audio upgrade designed for 2024 and newer Road Glide and Street Glide models. You can find exact fitment details on the product page (https://rockfordfosgate.com/products/details/hd24-stg2/). The kit includes a set of the new TMS24-65 6.5-inch Element Ready speakers, complete with grilles, and a 1,000-watt amplifier.
The TMS24-65 speakers are the next evolution of Rockford Fosgate’s motorcycle speakers. They feature a carbon-filled curvilinear polypropylene woofer cone and a Santoprene rubber surround. The speaker utilizes the Vertical Attach Surround Technique (VAST) design to maximize cone area, thereby increasing efficiency and bass output. The 1.5-inch Kapton voice coil is larger than that of previous models, providing improved power handling. The tweeter remains mounted in the center of the cone, delivering perfectly aligned output at all angles. The frequency response has been improved over the 1st generation by providing extended low-end response and reduced distortion for a richer, more balanced listening experience.
The new amplifier is a masterpiece. First, it connects directly to the A2B digital audio bus output of the Skyline OS factory radio, eliminating the need for expensive interfaces. The TMA-1000X4i amp is rated to produce up to 200 watts of power per channel into four 4-ohm or 2-ohm loads. It can be bridged to deliver 400 watts into a pair of four-ohm loads. The amplifier’s dynamic power output is 1,200 watts.
The amplifier includes an integrated digital signal processor. Your installer can configure the amp for the type of stage installed using the RF Connect app. These are DSP presets done by Rockford Fosgate with the EQ, Gain, and Crossover settings pre-configured to take the hassle out of tuning the amplifier manually.
The HD24-STG2 kit includes an RFK-HD24 amplifier installation kit, complete with a bracket and all necessary wiring, for your motorcycle. Best of all, everything is designed to connect directly to the factory audio system wiring, eliminating the need for cutting or splicing. This means your warranty remains intact.
Rockford Fosgate HD24-STG3 Upgrade
If you are looking for even more sound from your Harley-Davidson, then the Stage 3 kit is the way to go. The Rockford Fosgate HD24-STG3 builds upon the features of the Stage 2 kit by incorporating the HD24BL69 bag lid speaker kit. This kit includes a set of the new TMS24-69 6×9-inch Element Ready speakers, upgraded cut-in speaker grilles, and all the wiring necessary to connect to the TMA-1000X4i amplifier. It’s important to note, this system is designed for “blank” saddlebags, so if you already have color matched speaker lids, the HD24-STG2 + TMS24-69 speakers is a better choice.
The new 2024 and later saddlebag speaker kit plays louder while occupying less cargo space. It even works with the Power Lock Kit. Being Element Ready means everything can withstand water, dust, prolonged UV exposure, and harsh vibrations —such as those experienced by Road Glide and Street Glide bikes.
