8-Channel Class D Full-Range Car/Marine Amplifier, 100 W x 8 @ 2 Ω / 75 W x 8 @ 4 Ω – 14.4V
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 @ 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 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, 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 eight amplifier channels directly from the driver’s seat or cockpit.
Here are a few examples of how the XDM800/8 can be used:
- Eight-channel Satellite Amp: drive four pairs of speakers with 75 W x 8
- Big Four-Channel Satellite Amp: bridge to produce 200W x 4 @ 4Ω
- Six-Channel System Amp: drive front and rear satellites with 75 W x 4 @ 4Ω, plus two 4Ω subwoofers with 200 W each
- Staggered Six-Channel Satellite Amp: drive front speakers with 200 W x 2 @ 4Ω, plus four 4Ω speakers with 75 W each
- Staggered Five-Channel Satellite Amp: drive three front speakers with 200 W @ 4Ω + rear speakers with 75 W x 2
- Four-Channel System Amp: drive left and right speakers with 200W x 2 @ 4Ω, plus two 4Ω subwoofers with 200W each
Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
