Ready to upgrade the sound on your 2015-up Harley-Davidson® Road Glide® or 2014-up Street Glide®? Go big with Rockford Fosgate's Power Series Stage 2 kit. Designed to fit your Harley, this package features 6-1/2" fairing speakers and a compact, weather-resistant 4-channel amplifier with an installer-friendly amplifier kit. It's a big step up in audio for your Harley.

Better sound for your Road Glide or Street Glide

Ready to upgrade the sound on your 2015-up Harley-Davidson® Road Glide® or 2014-up Street Glide®? Go big with Rockford Fosgate's Power Series Stage 2 kit. Designed to fit your Harley, this package features 6-1/2" fairing speakers and a compact, weather-resistant 4-channel amplifier with an installer-friendly amplifier kit. It's a big step up in audio for your Harley.

Phenomenal sound for the fairings

The Stage 2 package includes two Rockford Fosgate TMS65 6-1/2" speakers that will fit right into the fairing locations on your Harley-Davidson. These rugged, weather-resistant coaxial speakers will really boost your bike's audio quality, packing a lot of sonic punch into a rugged, road-ready design. The big VAST (Vertical Attach Surround Technique) surrounds give the speakers 25% more cone area without compromising ease of installation. The result? You'll get more performance from a smaller speaker, which is pretty much the ideal for a motorcycle.

A compact, powerful amp

The Power Series TM400X4ad 4-channel amplifier uses Rockford Fosgate's proprietary Class AD technology to draw big power with less current draw from your bike's electrical system. It's made for the road, with conformal-coated circuitry and stainless steel hardware. This compact amp rocks hard and runs cool, even when it's tucked into a tight space. You'll install the amp using the included RFK-HD14 kit which includes everything you need for the job, from mounting plate and wiring harnesses right down to the screws.

Compatibility note: This kit is designed to work with 2015-up Harley-Davidson® Road Glide® or 2014-up Street Glide® touring bikes only.

Important Note: All 2014-up Harley-Davidson radios use a “high fidelity” EQ curve which will cause severe distortion in any audio upgrade. After installing this system, you'll need to get your radio reflashed by your Harley-Davidson dealer.

Product Research


Overview: The Rockford Fosgate HD14RGSG-Stage2 sound system has been specifically designed for installation on select 2014-up Harley-Davidson motorcycles. The system includes a 4-channel 400 watt amplifier, amplifier wiring kit, and two 6-1/2" speakers for the fairing.

  • Note: To retain proper fidelity and avoid speaker damage, your factory radio will need to be flashed by an authorized Harley-Davidson dealer after installing the Rockford Fosgate sound system.

Compatibility: The HD14RGSG-Stage2 sound system is compatible with the following model Harley-Davidson motorcycles:

Year Make Model Fairing
2015-Up Harley-Davidson Road Glide Shark Nose
2015-Up Harley-Davidson Road Glide Special Shark Nose
2014-Up Harley-Davidson Street Glide Bat Wing
2014-Up Harley-Davidson Street Glide Special Bat Wing

4-Channel Amplifier: The included TM400X4ad is a full-range 400W amplifier rated at 100 watts x 4-channel. As part of the HD14RGSG-Stage2 installation package, the 4-channel amplifier uses the front channels to power the included full-range speakers, while the rear channels can be used for adding an optional pair of TourPak or saddlebag speakers. Pre-formed wiring harnesses for the amplifier and the speakers are provided, greatly reducing the installation time.

  • Class-AD: The TM400X4ad features Rockford Fosgate's proprietary Class-AD technology, allowing it to produce more power with less current draw from the vehicle's charging system.

  • Constant Power: Constant Power is a patented circuit topology that provides instantaneous delivery of output power with varying impedance loads. This means the amp can provide 100 watts of continuous power (RMS) into either a 4- or 2-ohm load.

  • C.L.E.A.N. Setup: The TM400X4ad features clip LED indicators for both inputs and outputs, helping you easily match the source to the amp.

  • 3-Stage Airflow: Air vents in all 4 corners of the amp provide air-flow through internal channels on both sides of the circuit boards. Working in conjunction with laterally mounted heat-sinks, this effectively exhausts heat, allowing the amp to run cooler for optimum performance.

  • DSM (Discrete Surface Mount): In the manufacturing process high speed robotics are used to place 1% tolerance parts and large board traces. DSM improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

  • Element Ready: Rockford Fosgate's "Element Ready" classification means the TM400X4ad is well protected against dust, UV rays, and corrosion, with conformal coated PCB boards and stainless steel hardware.

  • Controls: The TM400X4ad offers a variety of controls to fine tune your system.

    • Clip Indicators: Both sets of input channels include Clip indicators for both the inputs and outputs.

    • Input Level: The front and rear channels have independent input level (gain) controls, adjustable from 150mV to 12V.

    • 2/4 Channel: When using only one set of inputs, set this switch to 2-channel and connect the inputs.

    • Crossover: The front and rear channels have independent 3-way crossover switches. Each can be set to low-pass, all-pass (crossover is bypassed), or high-pass.

    • Frequency: Working in conjunction with the Crossover Switches, two Frequency dials determine the cutoff frequency, ranging from 50Hz - 250Hz.

    • Punch EQ: This control also works in conjunction with the Crossover by creating a boost at the cutoff frequency, either for high-pass or low-pass settings. If the Punch EQ is turned up when the Crossover is set to AP (all-pass), both bass and treble frequencies will be boosted.

    • Power LED: The Power/Protect LED on the front of the amp illuminates blue when the amp is turned on and operating normally; it illuminates red when one of the protection circuits has engaged (short circuit, impedance too low, or temperature too high).

  • Connections: The TM400X4ad features the following power, signal input, and speaker output connections.

    • Power Connections: The power, ground, and remote turn-on terminals are c-clamps on a removable plug, with each terminal accommodating up to 8-gauge wire. A Phillips-head screwdriver (not supplied) is required to tighten/loosen the terminals.

    • Signal Input:  The TM400X4ad is compatible with either line-level (RCA) or speaker-level inputs. The included input harnesses have Molex plugs on one end (plugs into the amp) and female RCA plugs on the other. When using speaker-level inputs the RCA end is removed and the four individual wires are used.

    • Speaker Output: The included speaker output harnesses have Molex plugs on one end (plugs into the amp) and bare wires on the other.

TMS6SG: The TMS6SG 6-1/2" full-range coaxial speakers are designed to fit the fairing speaker location. The weather resistant speakers feature a reinforced polypropylene cone, with Santoprene surround and Neodymium motor structure, along with a ultra-efficient 1" dome tweeter. The speakers include grilles and mount in the factory location using the factory hardware.

  • Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.

  • CEA-2031 Compliant: The power handling specifications conform to the CEA-2031 industry standards; meaning the speaker has the capacity to handle its rated power under continuous demand, not just for an instant.

  • VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket. The surround is made of Santoprene rubber.

RFK-HD14 Wiring Kit: The 2014-up Harley-Davidson Road Glide and Street Glide amplifier wiring kit includes pre-cut, pre-loomed 100% Pure Crystal-Oxygen Free Copper (PC-OFC) wiring for installing the sound system, meeting or exceeding American Wire Gauge (AWG) requirements. It includes 8-gauge power and ground wires for running to the battery, as well as all input and output harnesses for running signal from the headunit to the amp and then on to each individual speaker. The battery power wire includes an inline fuse holder with installed 60A Maxi fuse. The amplifier wiring kit also includes an additional amplifier heatsink, for better heat dissipation at higher volumes, and an amplifier mounting bracket.

Customer Q&A

5 questions already asked

I have a '22 RGS and was wondering does the amp fit in the front fairing near the radio or do you need to install it in the saddle bag? I was told by someone that the new fairing doesn't offer the room to mount the amp with the radio.

Greetings, and thank you for your question. I reached out to Rockford Fosgate because there was no info regarding the 2022 fairing in the manual, or their You Tube install guide page. The rep at Rockford said there is another package offered by HD dealers as an OEM upgrade. Only available from an HD dealer. That package would have the amplifier go into the saddle bag. The kit from our website still has the amp located in the fairing. Hope that helps.
[ Thomas J.  Jan 23, 2023 ]  Staff
Can the stock Harley speaker be used as second set of speakers in lower fairing ?
[ Bambam  Oct 09, 2021 ]
3 answers
No, the speakers are only compatible with the Harley amp. Once you get the head unit flashed to work with the frost gate amp the Harley speakers will be distorted
[ James  Oct 10, 2021 ]
Nope, the power handling ohms and flashing your head unit
[ tim  Oct 09, 2021 ]
It will definitely fit but why would you? They sound horrible compared to the Rockford Fosgates!!

Is everything you need in the kit?
[ Carl  May 31, 2021 ]
6 answers
Yes. It comes completely plug and play. All instructions and wiring pigtails for the stock speakers as well as extras for lower fairing and saddlebag speakers are included. The only thing you have to do is get factory radio flashed at a local stereo shop that is authorized to do so. I followed a youtube video on disassembly of the fairing which was easy. Factory radio still played and sounded much better even before I was able to flash it. Great system.
[ Henry  Jun 02, 2021 ]
yes.. very simple install.. make sure to have your radio flashed before playing..
[ james  Jun 01, 2021 ]
Yes it is
[ tim  Jun 01, 2021 ]
Yes it is. I took the box as it arrived to the shop to get it installed and all was peachy.
[ WALTER  Jun 01, 2021 ]
I have not installed yet, but was told by the crutch field assistant everything I needed was included.
[ Rusty  Jun 01, 2021 ]
Yes there was everything in the kit .
[ MICHAEL  May 31, 2021 ]
I want to add two 8 inch mid-range speakers to my saddlebag lids? Other than the speakers, what else do I need with THIS kit?
[ James  Jul 30, 2020 ]
