ALPINE MRV-F300

Tens of thousands have been based on V-Power amplifiers for reliable, quality power. Now in their fourth generation, the V-Power amplifiers continue this legacy and prove that the loud play never looked or sounded better. Yes, it's possible to improve something good.

Overview

• Total maximum power: 640 W

• 75W RMS x 4 (2Ω, 14.4 V, ≤ 1% THD + N)

• 50W RMS x 4 (4Ω, 14.4 V, ≤ 1% THD + N)

• Same amount of power in 40% smaller chassis

• Evolution to Class D digital platform

• New snap-on terminal covers for easy installation
