Overview: The Rockford Fosgate TM400X2ad is a 2-channel Power Series moto-marine amplifier with a rated power output of 200 watts per channel at 4-ohms or 2-ohms. This Element Ready amplifier can be used on motorcycles, ATVs, 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 200 watts RMS x 2 channels. Additionally the power output is 200 watts RMS x 2 channels into 2Ω and 400 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 TM400X2ad 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. At least 2-3 inches clearance should be provided around the fan intake and the exhaust vents to optimize air flow.
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 a single input level control, 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 level.
Crossover: The amplifier has a built-in Butterworth crossover, variable from 50 Hz to 250 Hz with a slope of 12dB/octave. It can be set to high-pass, all-pass (full range), or low-pass operation. The rotary frequency setting can be adjusted with a small screwdriver.
Punch EQ: The amplifier has an Punch EQ function that changes with the crossover switch. 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.
Power Connections: The TM400X2ad's power, ground, and remote turn-on terminals are located on a single, removable plug. This allows you quickly and easily connect or disconnect the amplifier. Each individual terminal on the plug is a captive c-clamp connector which will accommodate up to 8-gauge wire. A Phillips- or flat-head screwdriver (not supplied) is required to tighten/loosen the terminals.
Fuse: The amplifier does not have an on-board fuse. A 60-amp fuse should be placed on the power wire within 18" of the battery.
Speaker Connections: The amplifier is equipped with a speaker output harness, which connects to the amplifier via a 4-pin plug. The speaker wires should be spliced to the 16-gauge bare wires on the 8" pigtail. To bridge the amplifier, you should use the left positive (white) and right negative (gray/black stripe) terminals.
Signal Input: The amplifier's Differential Inputs will accept either a line-level or speaker-level input on the Molex-style connector. The included input harness has a 4-pin Molex plug and dual RCAs. A line-level signal can simply be connected via RCA cable from the source unit to the input harness. For a speaker-level signal, you can cut the RCA connectors from the input harness and splice the wires to the speaker wires of the source unit. When using a speaker-level input signal, the auto turn-on feature is active and the remote turn-on terminal becomes a 12 volt output, which can be used to turn on/off an additional amplifier or other component.
Punch Level Control (PLC): An RJ-45 jack is provided for connecting the optional PLC2 Remote Punch Level Control (sold separately), allowing remote control of the output level of the amplifier. The PLC2 conveniently mounts under the dash, inside the center console, or in the glove box.
Optional Custom Mounting Kit: The optional RFKHD9813 amplifier installation kit is designed for custom-mounting the TM400X2ad to compatible Harley-Davidson motorcycles. The kit includes a mounting plate, heatsink, and wiring kit. You may qualify for a One-Year Extended Warranty when you install the TM400X2ad with a matching Rockford Fosgate Amplifier Installation Kit.
