About the Alpine MRV-F450

Let Alpine's 5-channel MRV-F450 V12 series amplifier deliver the juice to your entire speaker system. It provides 4-channel amplification to your main speakers, while a fifth channel drives your subwoofers.

Let Alpine's 5-channel MRV-F450 V12 series amplifier deliver the juice to your entire speaker system. It provides 4-channel amplification to your main speakers, while a fifth channel drives your subwoofers.

The unstoppable power of this Alpine V12 Series amp comes from the massive transformers and fast MOSFET power supplies. Extra-large capacitors deliver additional current when needed to fuel musical peaks. The amps are built using Alpine's STAR Topology design to greatly reduce internal noise, keeping the signal clean so that your speakers can perform better.

The internal Bass Engine® provides built-in crossovers for adjusting the amplified frequencies. The subwoofer channel also has a subsonic filter and Bass EQ, which lets you tune the low frequencies for optimum effect in your vehicle. The top-mounted controls are conveniently hidden and protected by a flip-up top cover. Likewise, your cables are concealed under the front cover, which can be removed to save space.

    Features

    V12 Amplifier: This amplifier is part of Alpine's V12 series of amplifiers.

    STAR Topology: Alpine's unique STAR (Signal Transit for Accurate Response) Circuit PCB design provides a single common ground for all amp sub-blocks, preventing ground interference and minimizing internal noise.

    Bass Engine: Bass Engine is a set of functions that help provide you with more control over your system in order to tailor the sound to your personal tastes.

    Verification Certificate: The amplifier comes with a certificate that informs you of the per channel RMS output of the particular amplifier. It lists the model number, serial number, test date, and the test conditions (voltage, impedance).

    Built-in Variable Electronic Crossover: The built-in low-pass/high-pass crossover for the stereo channels is adjustable from 50Hz to 200Hz. The built-in low-pass crossover for the subwoofer channel is adjustable from 30Hz to 200Hz.  All crossovers have a slope of 12dB/octave.

    Bass EQ: 0 to 12dB of bass boost, centered at 50Hz, may be dialed-in to produce the bass response desired from your system.

    Sub-sonic Filter: The sub-sonic filter is used to filter out low frequencies that you cannot hear but can "rob" power from the amplifier. The sub-sonic filter on this amplifier affects the subwoofer channel only, and selectable between "30Hz", "15Hz", and "OFF".

    Protection Circuitry: The protection circuitry guards against accidents and undesired operation. Included are Over-voltage and Thermal overload.

    Controls

    Top of Amplifier: The amplifier has a metal hood that flips up to reveal the control panel. The control panel consists of the following controls:

    • Front, rear, and sub variable gain controls: these rotary controls allow you to match the input sensitivity of the amp to the particular source unit you are using
    • Front and rear channel frequency controls: these rotary controls allow you to adjust the crossover frequency from 50Hz to 200Hz
    • Sub channel frequency control: this rotary control allows you to adjust the crossover frequency from 30Hz to 200Hz
    • Crossover mode selector switches: lets you select high-pass, low-pass, or full-range operation for the speaker outputs of channels 1/2 & 3/4
    • Subsonic filter: lets you select between 30Hz, 15Hz, or OFF
    • Bass EQ: this rotary control allows you to adjust the boost or cut from 0 to 12dB
    • Input channel selector switch: Allows you to select between 4-channel, 5-channel, and summed input options

    Inputs and Outputs

    Specifications

    RMS Power Rating (measured at 14.4V):

    • Per Channel Into a 2-Ohm Load: 60 watts x 4
    • Bridged Into a 4-ohm Load: 120 watts x 2

    RMS Power Rating (measured at 12.0V):

    • Per Channel Into a 4-Ohm Load: 30 watts x 4, + 150 watts x 1
    • Per Channel Into a 2-Ohm Load: 40 watts x 4
    • Bridged Into a 4-ohm Load: 80 watts x 2
