Description
The JL Audio MX280/4 is a compact four-channel amplifier built for marine and powersports use. Its high-speed NexD Class D design delivers clean, efficient full-range power without straining the boat's charging system, and a dual-range input accepts everything from line-level to high-power speaker-level signals for flexible integration.
Rated at 50 W RMS per channel into 4 ohms (70 W into 2 ohms, or 140 W bridged into 4 ohms), the MX280/4 drives up to two pairs of speakers. A conformal-coated circuit board, gasketed cover and stainless steel hardware provide IPX7 water resistance for open-cockpit installation.
