Speakers

Injection-Molded Polypropylene Woofers: The woofer cones are mineral filled, injection-molded polypropylene. This molding process assures a uniform cone thickness for superior linearity and clarity. It is also light weight and rigid for decreased distortion and improved bass response.

Butyl Rubber Surrounds: The butyl rubber surrounds dampen unwanted harmonic distortion while maintaining linear geometry under extreme weather conditions. This leads to less distortion, superior frequency response, and superior durability.

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

Tweeters: Each speaker features a 3/4" PEI (Poly-Ether-Imide) dome tweeter; PEI is a polymer film that produces a wide soundstage for superior imaging.

StampCast Basket: The P16 features StampCast steel baskets for added rigidity.

Mounting: While Rockford Fosgate calls the P16 a 6" speaker, they are sized to mount in standard three-hole and four-hole 6-1/2 applications.

Adapter Brackets: The included brackets are specifically designed for use in select '98 to '13 Harley-Davidson models.

Amplifier

Boosted Rail Technology: The PBR300x4 uses Boosted Rail Technology (BRT), an efficient design that doesn't use a switching power supply. The PBR300x4's average efficiency is more than 75%, meaning it doesn't generate much heat and can maintain a small footprint.

Signal Input: The PBR300x4 is compatible with either line-level (RCA) or speaker-level inputs.

Auto Turn-on: When using speaker-level inputs the amp will automatically turn on when it senses an input signal (4 volt minimum). The threshold voltage (DC offset) for auto turn-on is adjustable from 4 volts to 6 volts.

Dynamic Thermal Management (DTM): DTM Evenly distributes excess heat across the entire extruded aluminum heatsink.

MEHSA³: MEHSA³ (Maximum Efficiency Heat Sink Application-Third Generation) is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. The multi-layer insulated metal MEHSA substrate operates with minimal thermal resistance, spreading heat both downward and outward to quickly dissipate heat from each device across the heatsink. This allows greater power output, enhanced thermal stability, and maximum reliability.

NOMAD: NOMAD (NOn-Multiplying Advanced Decision) is an intelligent protection circuit that uses an analog computer to make real time decisions regarding temperature, voltage, current and impedance. The unit is protected without limiting sound output unless needed.

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.

LEDs: The Power/Protect LED on the right side 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). The BRT LED on the left side of the amp illuminates white when the boost mode is engaged.

Crossover: The front and rear channels have independent crossover switches. Each can be set to low-pass, all-pass (crossover is bypassed), or high-pass. The crossover point is fixed at 80 Hz and the slope is 12 dB/octave.

Gain: The front and rear channels also have independent input gain controls, adjustable from 150mV to 11V.

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

DC Offset: The DC offset threshold voltage for the auto turn-on circuit is adjustable from 4 volts to 6 volts (useful with speaker-level inputs).

Custom Mounting Kit

Overview: The Rockford Fosgate RFKHD9813 is an amplifier installation kit, designed to add a Rockford Fosgate compact chassis amplifier to select 1998-2013 Harley Davidson motorcycles. The kit contains a mounting plate, power, signal, and speaker wiring.

Kit Contents: The RFKHD9813 amp installation kit contains the following:

• Mounting plate/Brackets: The mounting plate is designed to hold the amplifier, and provide an additional heatsink to cool the amp. A large bracket (labeled Type 1) is used on Road Glide and Road Glide Ultra models, and mounts to the clutch-side turn signal bracket. A smaller bracket (Type 2) is to be used on Ultra Glide, Electra Glide, and Tri Glide motorcycle fairings, and mounts the amp to the top of the factory radio. (It does not work on models with the Communication Module.) Hardware is included for mounting the brackets to the plate.
• Power and Ground Harness: This harness has 8-gauge power and ground wire terminated into a Molex plug that directly connects to the amplifier. The other ends of the cables have ring terminals to connect the wiring directly to the battery. The power wire has an in-line fuse holder with a 60A MAXI fuse. The power wires are cut to length: Power wire is 74", while the Ground wire is 53".
• Front Speaker Input Harness: This pre-terminated, 18" harness has a 4-pin Molex plug that connects directly to the amp's front input socket, and to the factory front speaker wire harness.
• Front Speaker Output Harness: This 32" pre-terminated 16-gauge speaker output harness has a 4-pin Molex plug that connects directly to the amp's front output socket, and female quick slides that connect to the motorcycle's front speakers.
• Rear Speaker Output/Input Harness: The longest harness in the kit (at 9.5 feet) contains both the input and output connectors for the rear channels. This harness is used only when installing a 4-channel amplifier. The input connector is a 4-pin Molex plug that plugs into the amp's rear input socket. Female quick slides connect to the factory stereo's rear speaker wire harness, and to the rear speakers. The input wires are color coded purple and green, while the output wires are silver and bronze, and labeled for connecting to the clutch-side and brake-side rear speakers.
