About the Alpine MRD-M605
Alpine's MRD-M605 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 400 watts of bass-bumping power to a 4-ohm load (600 watts at 2 ohms ) — an outstanding way to get the shake on with a sub or two!
The MRD-M605 features computerized digital controls that are second to none. Top-mounted Bass Engine digital controls allow a high level of fine-tuning, including a subsonic filter to remove inaudible, power-wasting ultra-low frequencies and Bass EQ, adjustable from 0-16 dB at 45 Hz.
You'll find a set of preamp outputs for routing signal to another amplifier for additional power. 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-M605 running strong over the long haul, Alpine designed the amp for optimal internal air flow, including a built-in variable-speed cooling fan.

Specifications
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-M605 features a blue backlit display that allows you to monitor the DC input voltage or 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, and can 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.
Battery (+12 V)/Ground (GND): The Battery and Ground terminals are set-screw terminals that will accept up to 4 gauge wire. A 4mm Allen wrench is included to tighten/loosen the set screws.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-M605 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: 400 watts x 1
- Into a 2-Ohm Load: 600 watts x 1
Note: Minimum impedance is 2 Ohms.

I upgraded to this amp from the Alpine MRD-M301 so that I could use the amplink function with my Alpine CDA-9855. This amp sounds amazing, and the actual rating from Alpine was 637W. I highly recommend this amp to anyone looking for an awesome sound from their subs.
