Our take on the Alpine MRD-M1005 by Crutchfield's Ken Nail
Alpine's MRD-M1005 amplifier is a monster mono machine, ready to deliver the big watts to your subs. This powerful Class D member of Alpine's V12 amplifier series delivers 700 watts of bass-bumping power to a 4-ohm load (1000 watts at 2 ohms) an outstanding way to get the shake on with a multi-sub system.
The MRD-M1005 features state-of-the-art, computerized digital controls that allow a high level of system adjustment. Included are a subsonic filter to remove inaudible, power-wasting, ultra-low frequencies, and a Bass EQ for personalizing the level of bump in your music.
Thanks to Alpine's Amp Link, you can connect this amp to compatible Alpine receivers with only a single cable (cable sold separately, not included), and make many amp adjustments with the controls on your Alpine receiver. Fine-tuning your system is easier than ever. For multi-amp systems, the MRD-M1005 has a set of preamp outputs for easy routing of the signal to another amplifier.
The extra-large wiring terminals will let your bass really hit, since heavy-gauge power and speaker wires let the power move more efficiently into and out of the amp. To keep the MRD-M1005 running strong over the long haul, Alpine has designed the amp for optimal internal air flow, including a built-in variable-speed cooling fan.
Note: Sorry, Crutchfield cannot ship Alpine products to Guam or Puerto Rico.

V12 AccuClass-D Mono Amplifier: The V12 AccuClass-D amplifier design delivers massive power without correspondingly huge current draw. This amplifier's true digital design keeps the signal purer and makes the amp extremely efficient (approximately 80%). V12 AccuClass-D amps use digital signal processing to adjust input gain, crossover point, and Bass EQ, all controlled using the Alpine Digital Control Center located under the top-mounted access panel.
Hood: The amplifier has a hinged brushed aluminum hood that flips up to reveal the control panel and LCD display. The control panel consists of three buttons: Mode, Up (>), and Down (<). These buttons are used to navigate the menu which includes all the adjustments on the amp. When closed, the LCD display is visible through the plastic window. Two Allen-head screws secure the hood.
Display: The MRD-M1005 features a blue backlit display that allows you to monitor the DC input voltage and the internal temperature (Fahrenheit or Celsius). The display is also used when adjusting the Amp ID, input gain, crossover point, and bass EQ.
Verification Certificate: The amplifier comes with a certificate that specifies the measured total RMS output of the particular amplifier. It lists the model number, serial number, test date, and the test conditions (voltage, impedance).
Bass EQ: A bass boost is available at 45 Hz. The boost level is adjustable from 0 to 16 dB in 2 dB steps.
Built-in Variable Crossover: The built-in low-pass crossover is adjustable from 30 to 200Hz with 13 settings (30, 38, 45, 53, 60, 72, 85, 95, 110, 125, 140, 170, and 200 Hz). The slope is switchable, 12dB/octave or 24dB/octave.
Subsonic Filter: The subsonic filter is used to remove low frequencies that you cannot hear but can "rob" power from the amplifier. The crossover point is switchable between 15Hz and 30Hz with a slope of 24dB/octave. The subsonic filter can also be turned off.
Multi-Amp Installation: Because the above Bass Engine adjustments are all digital and discrete, two of these amplifiers can be used to power the two voice coils of a DVC woofer. Note: Technically this is true of any amp, but with analog adjustments an oscilloscope is needed to ensure the outputs are identical.
3-Way Protection Circuitry: This amplifier has a 3-way protection circuitry to guard against damage from undesired conditions. It includes protection for Short circuit (excessive current), Over-voltage, and Thermal overload. When the amplifier goes into protection mode, the LCD display shows an Error code explaining the cause of the failure.
Remote (turn-on): The remote terminal is a set screw terminal that will accept up to 8 gauge wire. A 2.5mm Allen wrench is included to tighten/loosen the set screws.
Speaker Output: The speaker terminals are set-screw terminals that will accept up to 8 gauge wire. The same 2.5mm Allen wrench is used for this terminal.
RCA Input/Output: The amplifier includes gold-plated RCA line input jacks and gold-plated RCA line output jacks, there is no speaker-level input.
Amplifier Link: The amp has a female DIN jack for connection to a 2005 or newer receiver with Amplifier Link controls. The Amp Link feature on the new amplifiers is not backward compatible with pre 2005 receivers. An Alpine KCE-511M cable is needed to connect the amp to a compatible receiver. Up to 8 Amp Link compatible amplifiers can be controlled by the receiver using KWE-061M "Y" adapters.
CEA-2006 Compliance: The specifications given by Alpine for the MRD-M1005 amplifier comply with the new CEA-2006 Amplifier Power Standard from the CEA (Consumer Electronics Association). All manufacturers who comply with the standard can display the CEA-2006 logo on their product.
RMS Power Rating (measured at 14.4V):
- Into a 4-Ohm Load: 700 watts x 1
- Into a 2-Ohm Load: 1000 watts x 1
Note: Minimum impedance is 2 Ohms.
