The JL Audio XDM 4-Channel Full-Range 400 Watt 12V Marine Amplifier (010-03115-00) from Nomadic Supply Company® packs a serious full-range punch, generating 100 watts to each of its four channels into 2 ohms (14.4V, 1% THD). The advanced NexD high-speed switching design permits full-bandwidth Class D operation with extremely low distortion and remarkable efficiency in a compact chassis.
Suitable for car or boat installations, the XDM400/4 is built with marine-grade materials and features an exclusive dual-mode input filter for noise-free performance. Automatic turn-on via signal sensing or DC-offset sensing is onboard for easy factory system upgrades. Combine the XDM400/4 with an XDM600/1 monoblock to build a 1000 W amplification system to power four satellites and a subwoofer — and fit the whole thing under a seat or deck. All controls are protected beneath a gasketed, removable top cover for easy access.
