50HDS144

Overview: The Kicker 50HDS144 audio upgrade kit is designed for 2014-up Harley-Davidson Electra Glide, Street Glide, Ultra Glide, and Bat Wing Trikes (all with fairings). The kit includes a 4 x 45W amplifier, that mounts to the factory radio assembly with the provided bracket, replacement front 6-1/2" speakers with grilles, and a pre-made wiring harness specifically designed to integrate all provided parts into the factory wiring. The 50HDS144 weather-proof upgrade kit is loud and clear enough to be heard over road and wind noise, yet compact enough to be tucked away out of sight.

Notes: 

• The factory radio will need to be "flashed" in order to recognize the new amplifier. This can be done by a Harley-Davidson authorized dealer, or with an optional Kicker TRHDP Radio Flash Programmer (sold separately).
• Not compatible with factory Harley-Davidson Boom audio systems.

KPX300.4 Amplifier

Amp Overview: KPX series amplifiers are designed for motorized vehicles with small battery/charging systems; Kicker's new Direct Amp Technology uses the vehicle's charging system as its power supply, offering 90-percent efficiency. Little ventilation is required and with its small footprint, the KPX300.4 includes a mounting plate that allows the amp to mount underneath the factory radio.

Power Output: The KPX300.4 is a 4-channel amplifier designed to output 45 watts RMS x 4 channels at 4Ω (<1% THD+N), 75 watts RMS x 4 channels at 2Ω (< 1% THD+N), and 150 watts RMS x 2 channels at 4Ω bridged.

Controls: The controls for the amplifier include rotary gain controls for Channels 1&2 and 3&4, and 7 DIP switches. The DIP switches, located on the bottom of the amp under a rubber cover, can select the following:

• High Pass Crossover (Ch 1&2): 60Hz, 80Hz, 100 Hz, 120Hz or off, based on the configuration of two DIP switches
• High Pass Crossover (Ch 3&4): 60Hz, 80Hz, 100 Hz, 120Hz or off, based on the configuration of two DIP switches
• Fader: select On if running two sets of inputs, or Off if driving all channels with a single stereo input
• Input Level: select high (speaker level) or low (line level)
• Auto Turn-on: select 12V (amp turns on when +12 volts is applied to the remote wire in the harness) or DC (amp turns on when a 6 volt surge is detected from a speaker level source)

Input Signal: The KPX300.4 is capable of receiving either high- or low-level input signals, and you can select the input type on the end of the amp. The included input harness for the amp (RCA) but won't be required for this install since the main wiring harness includes a speaker-level harness that interfaces the factory wiring and plugs directly into the amplifier. The Input Sensitivity is 250mV-10.0V (High Level), while the Low Level Input Sensitivity is 125mV-5.0V.

Power Wiring: The included power and ground wires from the main harness can be inserted into the amplifier wiring terminal block and tightened with a flat or Phillips head screwdriver. The adapter then plugs directly into the amplifier. A pre-crimped ring terminal on the main power wire allows for easy attachment to the battery, and includes an inline 20A mini ATC fuse.

Speaker Output/Turn-on Lead: The speaker output wires and the amp turn-on lead are located on the same plug-in harness. Four pairs of 16-gauge speaker output wires are provided that connect directly into the factory wiring. A blue turn-on lead is pre-installed with the speaker-level input harness, for a direct connection from the radio's harness to the amplifier. A dummy load plug is provided to plug into the rear speaker output wiring, if no rear speakers are present on the bike.

Differential Audio: The differential audio circuit reduces the likelihood of picking up any engine noise, and helps lower THD (Total Harmonic Distortion).

Weather Resistant: The KPX Amps are weather-resistant, using a conformal-coated circuit board for protection against the elements. They also include no-rust stainless-steel mounting hardware.

PSC652 Speakers

Speaker Overview: The included Kicker PSC652 6-1/2" 2Ω speakers are designed to mount in the factory fairing locations and provide crisp, clean sound, even through a helmet.

Weatherproof Design: Featuring titanium tweeters and neodymium magnets, the PSC652 speakers are constructed with high-grade components to withstand the elements.

Power Handling: The PSC652 speakers can handle up to 60W RMS (120W peak power), making them a perfect match for the KPX300.4 amplifier.
