About the Alpine MRV-F345
Choose an Alpine V12 amp for excellent audio quality and outstanding watt-per-dollar value. With many of the same high-grade components used in Alpine's flagship F#1 lineup, these amps have the flexibility for system building and the backbone for non-stop power output.
The MRV-F345 4-channel amp produces 75 watts RMS per channel — perfect for driving most component systems or high-quality coaxial speakers. The clean power output allows the speakers to produce the fine detail and nuance that'll separate your system from the rest of the pack. In bridged mode, the versatile MRV-F345 delivers 300 watts from channels 3 and 4 (perfect for running a sub), while you can use channels 1 and 2 to drive the front speakers.
Alpine's Amp Link lets you connect this amp to compatible Alpine receivers with a single cable, providing a clean 4-volt signal to the amp. Amp Link also allows you to make many amp adjustments from your Alpine receiver, so fine-tuning your system is easier than ever.
You'll find the set of preamp outputs convenient for routing the signal to another amplifier in your system. 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.

Product Research
Top of Amplifier: The amplifier has a metal hood that is removed to reveal the control panel. The control panel consists of the following controls:
- Mode: Toggles between menu functions (Amp ID, Input gain, Bass EQ)
- Down: Adjusts menu items (down)
- Up: Adjusts menu items (up)
- CH 1&2 crossover switch: Select high-pass, low-pass, or full-range operation for the CH 1&2 speaker outputs
- CH 1&2 frequency control: Rotary control adjusts the crossover frequency from 30Hz-400Hz or 600Hz-8kHz (depending on frequency multiplication switch)
- CH 1&2 frequency multiplication switch: Select "x1" for frequency band 30Hz-400Hz or "x20" for frequency band of 600Hz-8kHz
- CH 3&4 crossover switch: Select high-pass, low-pass, or full-range operation for the CH 3&4 speaker outputs
- CH 3&4 frequency control: Rotary control adjusts the crossover frequency from 30Hz-400Hz or 600Hz-8kHz (depending on frequency multiplication switch)
- CH 3&4 frequency multiplication switch: Select "x1" for frequency band 30Hz-400Hz or "x20" for frequency band of 600Hz-8kHz
- Input channel selector switch: Select between 1/2, 3/4, and 1+3/2+4
