About the Kenwood Excelon X1200M

Power is the name of the game

The Kenwood Excelon "Gouriki" Series amplifiers sport the Japanese characters that stand for "power" and "strength" because these amps are strong and powerful. "Gouriki" amps feature dual power supplies that deliver more consistent voltage so your amp doesn't break a sweat when you're driving your system hard. Unique circuitry analyzes the signal going to and coming back from your speakers to increase the amp's control over cone movement, for tighter, punchier bass.


The X1200M subwoofer amp pumps out up to 1,200 watts RMS to your subwoofers — plenty enough for even the most power-hungry subs to fill your car with bass. Variable low-pass and infrasonic filters help you tune your sub system to sound its best in your vehicle, while preamp outputs send the audio signal to another amp in your system.

Features

CEA 2006 Compliant: The X1200M's power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. The amplifier features the following power specifications.

  • 4-Ohm RMS Power Rating: 800 watts x 1-channel in 4-ohm at 20-200Hz with 1% THD
  • 2-Ohm RMS Power Rating: 1200 watts x 1-channel in 2-ohm at 100Hz with 1% THD
  • Max Power Output: 2400 watts x 1-channel Peak

Mono-Power Amp Design: The Kenwood X1200M is designed with specific features to power your subwoofers with a frequency range between 20-200 Hz. This amplifier is not designed to power a full-range speaker.

Class D Amplifier: For subwoofer applications, Class D amps are very efficient and their small size offers installation flexibility. Before amplifying an incoming signal, a Class D amp converts the signal to digital. Digital signals can be amplified very efficiently, so you get a lot more power with less current. Less input current reduces power supply size and generates less waste heat, thus reducing the heat sink size. The amp then converts the amplified signal back to analog.

Dual Sigma Drive: This advanced negative feed back circuit improves damping factor and increases accuracy and sound quality. When a signal is passed to a subwoofer, like a 50Hz note, the speaker will move and create the note. However, because the speaker has mass and a suspension, it will not stop moving once it is in motion. This extra movement (sound) creates a type of distortion that is not part of the original signal. The negative feedback circuit senses this unwanted movement and send out an opposite pulse to stop the speaker like an electronic brake.

Dual Power Supply: This design provides one power supply for positive current and one power supply fro negative current. The result is cleaner voltage source, less failure due to short circuit or power loss due to variances in transformer tolerances, and less transformer noise even when the positive and negative loads are unstable.

Dressing Cover: All of the amplifier's control are located under a removable extruded aluminum dressing cover. The dressing cover also hides the amplifier's connections for a neat installation. The dressing cover can be removed using the included small hex-wrench to unscrew two M4 x 8mm hex-head screws that hold the dressing cover in place.

Cooling Fan: There is a cooling fan, one top vent, and two vents located on each side of the amplifier to help dissipate heat and ensure cool, reliable operation. Make sure not to block these vents or fans when you install the amplifier.

Protection circuitry: The amplifier features protection circuits that will turn the amp off in case of the following events:

  • Speaker output contacts ground
  • Speaker wire short-circuits
  • Unit malfunctions and DC is sent to speaker output
  • Internal temperature is too high
  • Loss of ground of head unit or amp

Controls

Gain Control: The X1200M features a gain control with the following adjustable input sensitivity - 0.2V to 5.0V.

Variable Low Pass Filter: The built-in variable LPF (50-200Hz) allows you to select a variable frequency and remove damaging high frequencies from the subwoofer pathway for more bass output with less distortion.

Infrasonic Filter: The infrasonic filter eliminates inaudible ultra low frequencies that can cause unwanted distortion. The filter can be adjusted between 15Hz to 40Hz depending on the subwoofer and enclosure being used.

Bass Boss Wired Remote Ready: The optional KCA-WR10 wired remote (113KCAWR10, sold separately) allows bass boost frequency adjustments (15-40Hz) and level adjustments (0-18dB) for bass. If you are using two amps, you can use a phone splitter so one bass boost can operate both amps.

Line Out Filter: The Line Out Filter switch changes the audio signal output to the Line Out terminal on the amplifier. You can choose for the X1200M to filter the audio output to the other amplifier connected via the amp's line output, or allow the X1200M to pass a non-filtered audio signal onto the additional amplifier.

Inputs and Outputs

Power And Ground Terminals: The amplifier features hex-head set-screw Power and Ground terminals that will accommodate 6 to 4 AWG wire.

Turn-On Terminal: The amplifier features a hex-head set-screw Turn-On lead terminal that will accommodate 12 to 8 AWG wire.

Speaker Terminals: The amplifier is equipped with two pairs of gold-plated speaker terminals for an easy parallel subwoofer connection.

RCA Inputs: The amplifier features one pair of gold-plated RCA input connections.

RCA Outputs: The amplifier has a set of line level outputs for feeding a stereo audio signal to another amplifier.

Fuse: The amplifier contains three 30-amp fuses.
