Features & Compatibility

Overview: The Rockford Fosgate HD14-SBSUB subwoofer system has been specifically designed for installation on select 2014-2021 Harley-Davidson motorcycles. The system includes; an M5-800X4 4-channel 400 watt amplifier, that gets mounted in the fairing; 2 saddlebag enclosures, each loaded with a Rockford Fosgate M1D2-10B Element Ready 10" subwoofer; and all the wiring and mounting hardware needed for installation.

Notes:

• The HD14-SBSUB can only be interfaced with select year/model HD motorcycles with a Rockford Fosgate sound system listed below.
• The subwoofer kit can only be used with standard size Harley Davidson ABS plastic saddlebags, and is not compatible with stretched or early generation fiberglass bags.
• If equipped with a factory Tour-Pak system, it must be removed before installing the subwoofer system.
• 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 (most likely already done if one of the following Rockford Fosgate sound systems was previously installed).
• Some cutting and drilling into the saddlebags will be required for installation.

Motorcycle Compatibility: The HD14-SBSUB sound system is compatible with the following year/model Harley-Davidson motorcycles:

¹Not compatible with factory equipped amplifier or bulkhead wiring harness in saddlebag.
²Not compatible with factory equipped stretched saddlebags.

Required Audio System: One of the following Rockford Fosgate sound systems (sold separately) must be installed for the HD14-SBSUB subwoofer system to be compatible.

Amplifier

Amp Overview: The Rockford Fosgate M5-800X4 is a 4-channel powersports amplifier with a rated power output of 100 watts per channel at 4-ohms or 2-ohms. This Element Ready amplifier is designed for use in motorcycles, ATVs, UTVs, or boats, and can withstand harsh environmental conditions.

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 2 channels 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. The M5-800X4 carries an IPX6 rating, making it impervious to water spray.

Class-AD: The M5-800X4 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.

MEHSA 4 Cooling: The amplifier features Rockford Fosgate's MEHSA 4 (Maximum Efficiency Heat Sink Application) technology that reduces MOSFET temperatures, lowers distortion, increases durability, and prolongs the output circuitry's life span.

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.

Note: A handy amplifier Tuning Guide is included for quickly setting the amplifier controls to match the existing Rockford Fosgate audio system.

PRESET: The M5-800X4 features Rockford Fosgate's PRESET setting (On/Off) that eliminates the need to set-up the amplifier when used with a compatible Rockford Fosgate ATV/UTV Stage 3 or Stage 4 audio kit (sold separately). When set to On, the PRESET circuitry automatically optimizes the front & rear input levels, Punch EQ, and crossover settings. If manually setting these adjustments, the PRESET switch should be set to the Off position.

Input Level: The amplifier has dual 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 crossovers for the front and rear channels, variable from 50Hz to 250Hz 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 +18dB at 45Hz. When the crossover is set to high-pass, the Punch EQ acts as a variable treble boost, 0 to +14dB at 12.5kHz. When the crossover is set to all-pass, both the bass and treble boost circuits are active.

Wire Connections: The M5-800X4 amplifier features pre-installed wiring harnesses for the audio input and speaker outputs, allowing them to be plugged directly into the existing wiring. A pre-configured power and ground harness provides the connection to the battery and includes an inline 40A ATO fuse.

Subwoofers

Subwoofer Overview: The two included M1D2-10B subwoofers come pre-installed in sealed enclosures that are designed to mount inside each saddlebag compartment. Drilling and cutting templates, along with mounting hardware are provided for installation.

Marine Tested: Rockford Fosgate uses industry standard tests (ASTM B117 salt/fog and ASTM G154 UV) to ensure the M1D2-10B subwoofers are durable in the difficult marine environment.

Connections: Each subwoofer is internally wired to water-tight connectors on the outside of the saddlebag enclosures. Pre-configured harnesses are provided for connecting the subwoofer enclosures to the audio system.

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

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.
