JL Audio XDM800/8 (D class) marine power amplifier (8-channel).

JL Audio XDM800/8 (D class) marine power amplifier (8-channel). 

The ultra-versatile XDM800/8 delivers eight channels of crystal-clear, full-range power and is capable of delivering a whopping 100 watts to each of its channels. 
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 XDM800/8 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.
The XDM800/8 includes a 12 dB / octave filter for each channel bank.

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 eight amplifier channels directly from the driver's seat or cockpit.
