Infinity Marine M7005A – 5-Channel Marine Amplifier | 65 Watt x 4 + 500 Watt x 1

Take full control of your boat’s sound system with the Infinity Marine M7005A, a 5-channel marine amplifier that delivers clean, powerful audio across your entire setup. Combining Class AB and Class D amplifier technologies, the M7005A provides precision sound for your speakers and subwoofer, ensuring every note and bass hit comes through with clarity — even in the toughest marine conditions.

This high-performance amplifier delivers 50 watts RMS x 4 + 320 watts RMS x 1 at 4 ohms, or 65 watts RMS x 4 + 500 watts RMS x 1 at 2 ohms, giving you the flexibility to power a full marine speaker system plus a dedicated subwoofer. The front and rear channels use Class AB circuitry for warm, detailed midrange and highs, while the subwoofer channel uses efficient Class D technology for deep, controlled bass.

Designed for versatility, the M7005A features variable high- and low-pass filters (32–320 Hz, 12 dB/octave), a bass boost control (0–12 dB @ 45 Hz), a phase switch (0°/180°), and a wired remote bass control module for easy adjustments at the helm.

Built for marine environments, this amp includes conformal-coated circuit boards, corrosion-resistant hardware, and a sealed chassis to resist moisture, salt, and UV damage.
