JL Audio XDM800/8: 8-channel amplifier, 800 W
The XDM800/8 is the 8-channel amplifier, 800 W in the JL Audio XDM series, powerful and compact amplifiers for boats and cars. It delivers 75 W RMS per channel at 4 ohms and 100 W RMS per channel at 2 ohms; bridged it reaches 200 W RMS x 4 at 4 ohms (figures with a 14.4 V supply).
It is a full-range model for speakers and comes in two versions, for 12 V and for 24 V systems.

- Differential-balanced inputs with dual-mode filter
- Automatic turn-on in three modes
- Footprint 374 x 180 x 52 mm
NexD technology
Advanced NexD switching takes efficiency above 80 percent: the amplifier draws less current, runs cooler and gives plenty of power reliably from a small chassis that is easy to place on board.
Inputs and turn-on
The dual-mode input filter, exclusive to the series, and the differential-balanced inputs keep noise away. There are three ways to switch on: automatic signal sensing, automatic DC offset sensing, both with a +12 V remote output for other equipment, or the conventional +12 V turn-on wire.
Signal processing
The filters are continuously variable, designed for those who take care over system tuning. The potentiometers are calibrated and detented. A remote level control, also in a water-resistant version, can be added as a separate accessory.
The XDM series
The series includes full-range stereo amplifiers with 2, 4, 6 and 8 channels, system amplifiers with two or four full-range outputs plus one for the subwoofer, and subwoofer monoblocks. The 6-channel and 8-channel models also exist for 24 V systems. They all share the same height and the same depth: only the width changes.
Protection and build
If temperature climbs too high, the protection circuit lowers power instead of shutting the amplifier down: music carries on even in the toughest conditions. The chassis is powder-coated aluminium, against corrosion, and a sealed safety door shields the controls. The indicated fuse is 80 A, AFS, AGU or MaxiFuse type, and the power and ground cable 4 AWG copper at least. For the 24 V version the indicated fuse is 40 A. The 12 V model runs on 11 to 14.5 V.
