Bigger, better sound for your bike

Upgrading the factory stereo system on your 2015-up Harley-Davidson Road Glide® or 2014-up Street Glide® motorcycle doesn't have to be a hassle. Rockford Fosgate's HD14-TKIT features a compact, weather-resistant 4-channel amplifier, two 6-1/2" coaxial speakers, plus an installer-friendly amplifier kit. It's a great way to transform your sound without modifying your bike.

Road-ready speakers

Rockford Fosgate designed their TMS65 6-1/2" speakers specifically for the fairing locations on Road Glide and Street Glide motorcycles. These rugged, weather-resistant speakers will really boost your bike's audio quality, packing a lot of sonic punch into a compact package. The carbon-reinforced polypropylene cone, neodymium dome tweeter, and poly-cotton spider will withstand the weather, while the glass-reinforced polymer frame can handle rough roads or sizzling sunlight. And they even come with their own grilles. 

This package includes one set of speakers. The video above also shows the installation of an additional set of TMS65 speakers (not included).

A tough, efficient amp

The Power Series TM400X4ad 4-channel amplifier is made for motorcycle and marine applications. Rockford Fosgate's proprietary Class AD technology allows this compact amp to draw big power with less current draw from your electrical system, while the Constant Power feature keeps power consistent with varying impedances. It's built to stand up to outdoor life, with conformal-coated circuitry that withstands moisture and stainless steel hardware that resists corrosion.

Designed to fit your Harley

You can install the entire system without drilling or cutting. The wiring harnesses connect directly to the bike's harnesses, the speakers drop right into the existing cavities, and you even get an amp mounting kit, with a mounting plate, heatsink, and wiring kit. Upgraded cables provide the necessary current and voltage requirements for the amplifier, and the heat-sink keeps things cool when you're pushing your system hard.

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.

    Custom Mounting Kit


    Grilles: The TMS65 speakers include three sets of grilles to fit multiple Harley-Davidson applications, 2014 and later Street Glide fairing locations, 2015 and later Road Glide fairing locations, and 2014 and later rear Tour-Pak locations.

    Weather: The speakers are made weather resistant by the Santoprene front isolation spider, connecting the tweeter housing and woofer cone assembly.

    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.


    CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4Ω load with 1% or less Total Harmonic Distortion plus noise (THD+N). CEA-2006 allows consumers to compare amplifiers and receivers under identical conditions. The CEA-2006-rated RMS power output is 100 watts RMS x 4 channels. Additionally the power output is 100 watts RMS x 4 channels into 2Ω and 200 watts RMS x 1 channel bridged (into 4Ω).

    Element Ready: Rockford Fosgate's Element Ready Amplifiers are protected against dust, UV rays, and corrosion. Marine-grade, two-part epoxy-coated circuit boards are used to prevent corrosion due to exposure in moist and humid places. In addition, stainless hardware is used to help prevent rust and corrosion of all electrical connections.

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

    3-Stage Airflow: The amp's 3-stage airflow method efficiently rids the chassis of heat to keep the amplifier running cool. Dual fan forced induction pulls in fresh air. The air flows over the MOSFET transistors to cool them down, and out through the exhaust channel. The top and bottom heat sinks are decoupled, which allows the top to remain cool to the touch.

    DSM (Discrete Surface Mount): High speed robotics are used in the manufacturing process 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.

    CLEAN Set-Up: Rockford's integrated level setting technology, CLEAN (Calibrated Level Eliminates Audible Noise) replaces sophisticated test equipment with input/output clip LEDs, allowing you to match the source unit's output to the amp's gain, and optimize the amp's output. The input clip indicator works in conjunction with the audio source volume, illuminating red when the source reaches its clipping point. The output clip indicator works in conjunction with the input level dial on the amp, illuminating the appropriate color depending on the audio content used for the setup.

    Input Level: The amplifier has independent input level controls for the front and rear channels, conveniently accessible from the top. To accommodate the varying range of signal levels from today's factory and aftermarket radios, the input levels are adjustable from 150mV to 12V. A small flat-head screwdriver (not supplied) is needed to adjust the levels.

    Input Switch: With the input switch in the 2-channel position, connecting only the front inputs will send the signal to both the front and rear sections of the amplifier. In the 4-channel position, both front and rear inputs must be used.

    Crossover: The amplifier has dual built-in Butterworth crossovers for the front and rear channels, variable from 50 Hz to 250 Hz with a slope of 12dB/octave. They can be independently set to high-pass, all-pass (full range), or low-pass operation. The rotary frequency settings can be adjusted with a small screwdriver.

    Punch EQ: The amplifier has dual Punch EQ functions that change with the crossover switches. When the crossover is set to low-pass, the Punch EQ acts as a variable bass boost; 0 to +18 dB at 45 Hz. When the crossover is set to high-pass, the Punch EQ acts as a variable treble boost, 0 to +14 dB at 12.5 kHz. When the crossover is set to all-pass, both the bass and treble boost circuits are active.

    Custom Mounting Kit

    Overview: The RFKHD amplifier wiring and mounting kit includes precut lengths of power, ground, turn-on, and speaker wire, plus mounting brackets and hardware. The wiring and mounting kit will support 2-speaker and 4-speaker systems. The brackets have pre-drilled holes that allow you to bolt them to the chassis using the OEM mounting holes. The included wire harnesses are pre-loomed and terminated to use the OEM connectors.

    Note: Because the RFKHD is compatible with multiple Harley-Davidson models, and Rockford Fosgate amps other than the included TM400X4ad, parts are included that will not be used in this installation.

    Wiring: The cables included in the RFKHD use 100% Pure Crystal-Oxygen Free Copper (PC-OFC), and meet or exceed AWG (American Wire Gauge) requirements. The wires are terminated with the appropriate hardware. The wiring kit includes the following wires and harnesses:

    • Power Cable Assembly: The Power Cable assembly includes 5' lengths of 8-gauge power and ground wire, and a 15" amp turn-on wire. The power wire has an in-line Maxi fuse holder with a 60A Maxi fuse installed. The power/ground wires are terminated with ring terminals.
    • Rear Cable Assembly: The Rear Cable assembly consists of two 10' cables: Rear Input and Rear Output. The Rear Input has a 4-pin Molex connector on one end and male quick slides on the other ends of the color-coded left +, left -, right + and right - wires. (If only installing the two speakers included with this kit, this cable is not needed.)
    • Front Input Cable: The 19" Front Input Cable connects between the front speaker outputs of the head unit and the amplifier input. It has two proprietary connectors on one end and a 4-pin Molex connector on the other end. In this installation the Input Adapters (below) are also needed.
    • Input Adapters: The Input Adapters consist of two 6" lengths of speaker wire that extend between the Front Input cables (proprietary terminals) and the front speaker wires (quick slides).
    • Front Output Cable: The 22" Front Output Cable connects between the amplifier output and the front speakers. It has two proprietary connectors on one end, and a 4-pin Molex connector on the other end.
    • Output Adapters: The Output Adapters consist of two 12" lengths of speaker wire that extend between the Front Output cables (proprietary terminals) and the front speakers (quick slides).

    Installation Note: You'll need to get your 2014-up Harley-Davidson radio reflashed by a Rockford Authorized Motorcycle Dealer to get the best performance from this audio upgrade package.

    Does this kit include a template to cut out rear speakers on saddlebags?
    [ Kimo  Apr 28, 2019 ]
    8 answers
    I don't recall one being in the package. I didn't install speakers in bags; only replaced the speakers in the front fairing and in the front lowers.
    [ DeQuarry  Apr 29, 2019 ]
    No it does not. This kit is for front fairing. They make a saddle bag kit that comes with speakers which are 6x9 and a template.
    [ James  Apr 29, 2019 ]
    Yes it comes with one for each side, really easy to do
    [ Gary  Apr 28, 2019 ]
    Yes it does it's very easy their is also a step by step video fosgate put on YouTube for it the install stay clean and even!! With the foshate amp you can hear the setup at 90mph no issues
    [ SERAFIN  Apr 28, 2019 ]
    No this kit is only the front speakers.
    [ Kristopher  Apr 28, 2019 ]
    No, this kit is just the amp and front speakers with wiring and hardware.
    [ Michael  Apr 28, 2019 ]
    Yes, it includes everything you need. I haven't had time to do the install yet. There are a couple of utube videos on the complete install
    [ WILLIAM  Apr 28, 2019 ]
    [ Jeffrey  Apr 28, 2019 ]
    Does this come with all the wiring harnesses needed to attach the amp to both the battery and factory head unit on a 2019 SGS? Has anyone tried this with the Fosgate DSR1 eq, which is supposed to work in place of the flash?
    [ Bill  Feb 24, 2019 ]
    1 answer
    This kit does come with that wiring and all the wiring to connect it to the stock radio. We've got no information on the 2019 SG's yet, but as long as they are the same as a 2018, it will work. I doubt anyone has tried with with the DSR1 because that's no easy task given that this kit is meant to plug into factory wiring while the DSR1 changes factory systems to work with aftermarket amps (not amp designed for factory systems).

    If my bike has the Boom II audio system how well does this interface?
    [ Rob  Jan 16, 2019 ]
    3 answers
    This kit requires that you program the factory radio. If you don't do this it will blow the speakers. I found out the hard way and had to replace mine. Rockford Fosgate neglected to warn me of this in the installation instructions. I programed my radio and it now works very well but my bike does not have boom audio.
    [ john  Jan 17, 2019 ]
    This system would take the place of the BOOM audio system.
    [ Ken  Jan 16, 2019 ]
    This system is plug & play, it's very high quality crisp sound that can be heard at 80-100 mph no problem. I have to say though the Boom audio system sounds just as well if not better. My friend has a 2018 CVO Roadglide & the Boom system has a deeper sound to it. Hope that helps.
    [ Gary  Jan 16, 2019 ]
    I have purchased this kit for my 2014 Ultra. It does not have cd player to use set up disc. Is there another option to get set up?
    [ Vicki  Jul 01, 2018 ]
    4 answers
    I haven't been successful in setting mine up. I cant use the disc either.
    [ john  Jul 06, 2018 ]
    You would have to take it to a Fosgate dealer
    [ Dacia  Jul 03, 2018 ]
    Put the disc into the CD ROM drive of any desktop or laptop computer. Import (rip) the files to the computer's hard drive in uncompressed WAV format. Copy only the track for the proper setup frequency to a USB flash drive. Plug the same flash drive into your Harley's radio for system setup. Don't forget, before setup, have the Harley dealer reset your radio per Rockford's instructions.
    [ Troy  Jul 01, 2018 ]
    Did not use the cd or even look at it. Dealer flashed radio for me.
    [ A  Jul 01, 2018 ]
    can you tell me what I settings on amp to start with on 2017 roadglide with just 2 fairing speakers? had radio flashed and sounds awful

    Will my stock battery power everything ok?
    [ Chris  May 12, 2018 ]
    5 answers
    2017 and newer Milwaukee Eight bikes (stock) have more than enough charging system for this upgrade.Some of the older bike owners have upgraded their charging system.
    [ Troy  May 15, 2018 ]
    Yes, this stereo set up was well designed specifically for motorcycle charging systems, very low amps are drawn at full power not putting the charging system under strain. I'm very happy with my purchase.
    [ Gary  May 15, 2018 ]
    [ Bill  May 15, 2018 ]
    If this all you intend on adding to the bike, yes. However, it will be best to upgrade the battery now to the Stinger HD battery as it is designed for audio applications on ATV and motorcycles.
    [ Stephen  May 15, 2018 ]
    I installed to the stock battery on my 2016 road glide special. No issues!
    [ Michael  May 15, 2018 ]
    After having the HD head unit flashed to take the stock EQ off, do you still have workable bass and treble controls ? Does Automatic Volume Control still work ?
    [ Captain Ron  Oct 17, 2017 ]
    2 answers
    The flash from dealer does not work effectively, replace your stock radio with the Sony XAV-100 as it is a direct fit and requires no cutting.
    [ Stephen  May 15, 2018 ]
    You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss specific compatibility with your system. They will be able to go over all the details regarding installation in your Harley to make sure everything will fit and work correctly. Thanks! :)
    [ Larry  Oct 23, 2017 ]  Staff
    Does the HD head unit need to be flashed after install?
    [ Chris  Jul 20, 2017 ]
    2 answers
    I had it done before the install as recommended in the Rockford YouTube video referring to the install. They basically are turning the stock EQ off in the HD headunit
    [ Stephen  Jul 21, 2017 ]
    Yes, you are required to take your bike to the Harley dealer for OEM head unit reflash. The factory settings have bass and treble boosted. After the recommended reflash (instructions included in this kit) the factory radio will have a flat output.
