Know before you buy
Yes, the M600/6 features a flexible design that allows you to bridge channels. You can configure it as a 6-channel system for full-range speakers or bridge pairs of channels to power subwoofers, providing up to 200W per bridged pair at 4 ohms.
Class-D technology is highly efficient, meaning it produces significantly less heat than traditional amplifiers while drawing less power from your boat's electrical system. This makes it ideal for compact marine installations where space and battery conservation are priorities.
Yes, the M600/6 is built specifically for marine use with a stainless-steel chassis and corrosion-resistant hardware. It is engineered to withstand the moisture and salt spray typical of boating environments.
This circuitry monitors the amplifier's internal temperature and voltage. If the unit begins to overheat or experiences a power issue, it automatically adjusts performance to prevent a total shutdown, ensuring your music keeps playing even during demanding conditions.
With dimensions of approximately 10.23 inches wide by 7.09 inches deep and only 2.05 inches high, this amplifier is designed for a compact footprint. Its 'hidden box' form factor makes it much easier to tuck away in confined marine spaces compared to larger, traditional amplifiers.
The M600/6 is a versatile amplifier that accepts standard audio inputs, but its NMEA 2000 compatibility and various connectivity options allow it to integrate smoothly with most modern marine head units and integrated boat systems.
