Rockford Fosgate HD14U-STAGE2

Features

Overview: The Rockford Fosgate HD14U-Stage2 sound system has been specifically designed for installation on select 2014-2021 Harley-Davidson motorcycles. The system includes a 4-channel 400 watt amplifier, amplifier wiring kit, and two pairs of 6-1/2" speakers, one pair for the fairing and the other for the TourPak location.

• 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 HD14U-Stage2 sound system is compatible with the following model Harley-Davidson motorcycles:

4-Channel Amplifier: The included TM400X4ad is a full-range 400W amplifier rated at 100 watts x 4-channel. As part of the HD14U-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 (2 Pairs): The TMS6SG 6-1/2" full-range coaxial speakers are designed to fit both the fairing and the TourPak speaker locations. 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 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.
