Rockford Fosgate

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.

Where once the domain of only a few specialty brands, motorcycle audio speakers are now available from dozens of brands. Unfortunately, that doesn’t mean all the offerings sound good and play loudly. This Product Spotlight will examine the Rockford Fosgate TMS69 6×9-inch bag lid speaker set to explain what differentiates them from the other offerings in this category.

Rockford Fosgate TMS69 Specifications

The TMS69 set includes a pair of motorcycle-specific 6×9-inch speakers and hex-head mounting screws. Rockford Fosgate rates the speakers as capable of handling 100 watts continuously with peaks up of 200 watts. The speakers have a nominal impedance of four ohms and an impressive 1W/1M efficiency of 89 dB SPL.

For those into analyzing and understanding Thiele-Small parameters, the TMS69 woofers have a resonant frequency (Fs) of 75 Hz, an equivalent compliance (Vas) of 16.8 liters, and a total Q (Qts) of 1.63. The Xmax specification, which is measured at 10% THD using Klippel transducer evaluation equipment, is 3mm. Unless you know another manufacturer used 10% THD, you can’t compare this number with their maximum linear excursion specification.

Designing a speaker for an outdoor application, as you’d find on a motorcycle, is no easy feat. The Rockford Fosgate team spent countless hours cruising Arizona highways to audition dozens of samples of the TMS69 during the development process. The goal was to tailor the frequency response to what enthusiasts would enjoy while compensating for exhaust, wind, and tire noise. While most speakers in this market are marinized car audio speakers, the effort put into making the TMS69 truly unique is impressive. If you are looking for a speaker that sounds good at 75mph, you’re in the right place.

TMS69 Bag Lid Speaker Features

Motorcycle speakers differ from typical car audio speakers in several ways. First, they are designed with efficiency in mind. Getting more output for a given amount of power dramatically reduces how much current the amplifier driving the speakers consumes. This is crucial on a motorcycle where power is limited. Rockford Fosgate uses a low-mass polypropylene woofer cone with a high-Q suspension design. This will maximize output through the midbass region to ensure the drivers pack a punch; no pun intended.

Thermal power handling is also crucial, as the speakers are typically installed in airtight Harley-Davidson saddlebags. This means they can get quite warm. TMS69 speakers feature a huge 1.4-inch diameter voice coil to help dissipate heat efficiently.

These speakers have a shallow design, so they don’t take up valuable room in the saddlebag. Mounting depth is specified as being only 2.8 inches deep. The compact size is achieved thanks to a high-efficiency neodymium magnet structure. A second benefit to speakers that use Neodymium magnets is weight reduction. Each TMS69 weighs about a pound. Ceramic-magnet speakers, albeit cheaper, can be five times as heavy. Rockford Fosgate chose the Neodymium route because it’s much lighter than a traditional speaker with a large ceramic magnet, while still producing the same output. Added weight, especially at the top of the saddlebag, can affect the handling and stability of the motorcycle.

Materials and Design

When you look at the top of the TMS69, you’ll first notice the low-profile 25mm dome tweeter with a phase disc integrated into the grille. The disc helps ensure even sound dispersion at extreme frequencies. The small vertical waveguide around the sides of the tweeter help direct the output towards the driver.

To ensure the speakers are 100% water resistant, Rockford Fosgate has implemented a synthetic rubber surround between the tweeter post and the polypropylene woofer cone. This ensures water can’t get into the motor assembly should you get caught in the rain.

The last feature worth noticing is the massive amount of cone area afforded by the Vertical Attach Surround Technique surround. The way the surround attaches to the vertical sides of the basket allows the radiating surface to be much larger than competing products. In short, you get way more effective cone area and output for your money compared to other offerings.

Element Ready Design

While other products may claim water resistance, Rockford Fosgate takes building speakers for outdoor applications seriously. They use the term “Element Ready,” which means the speakers are water resistant and UV resistant. This means they won’t dry out and crack after prolonged sun exposure. The speakers are also subjected to vibration and impact testing to ensure all components remain secure. A solid design is crucial for a motorcycle, which experiences intense vibrations from the lumpy camshafts. The ultra-rigid glass-fiber reinforced polymer plastic frame is an example of putting durability at the forefront of the design.

Harley-Davidson Installations

The TMS69 speakers are available as stand-alone options. However, they are the heart of the popular and often imitated bag lid speaker kits; the TMS69BL14 for 2014-2023 Harley-Davidson® touring motorcycles, and TMS69BL9813 for 1998-2013 H-D® touring models. The kits feature a cutting template that allows your installer to modify the existing bag lids to accept the 6×9 speakers using the provided mounting brackets and grilles. This eliminates the need to try to paint-match aftermarket lids. If you want to bring the sound system on your Harley-Davidson Street Glide, Road Glide, Electra Glide, or Road King to life, these kits are a perfect upgrade.

Enhance Your Motorcycle Audio System with Rockford Fosgate Speakers

If the stereo system on your Harley-Davidson motorcycle doesn’t put a smile on your face when you crank the volume, drop by a local authorized Rockford Fosgate retailer and ask about an upgrade that includes the TMS65 fairing speakers, TMS69 bag lid speakers and their impressive amplifiers. You can find a local authorized retailer using the dealer locator at on the Rockford Fosgate website.
