JL Audio XDM600/6 (D class) marine power amplifier (6-channel).

JL Audio XDM600/6 (D class) marine power amplifier (6-channel).

The incredibly flexible XDM600/6 packs a serious full-range wallop and delivers a stunning 100 watts to each of its six channels into 2 ohms (14.4V, 1% THD). 
The technology that makes this much power possible in such a compact chassis is our advanced NexD™ high-speed switching design, which permits full bandwidth Class D operation with extremely low distortion and remarkable efficiency.
Suitable for car or boat installations, the XDM600/6 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. 
Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades.
With the XDM600/6, you have plenty of great use options. 
Configure it as a six-channel satellite amplifier with 75 W x 6 @ 4 Ω, or bridge four of its channels to create a staggered power four-channel amplifier with 200 W x 2 @ 4 Ω for your front satellites and 75 W x 2 @ 4 Ω for your rear satellites. 
You can also drive two subwoofers with 200 W each, plus a pair of satellites with 75W x 2.
The XDM600/6 includes a 12 dB / octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-500 Hz. 
With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), you have the ability to adjust the level of two, four, or all six amplifier channels directly from the driver's seat or cockpit.
