JL Audio XDM800/8

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.

Frequently Asked Questions (FAQ)


This is likely "Gain Hiss." Check the "Input Voltage" switch. If using RCA cables from an aftermarket radio, set it to "Low." If using factory speaker wires, set it to "High." Improper settings force the amp to amplify floor noise.
Yes. You can bridge any pair (1/2, 3/4, etc.) to get 200W x 4 at 4 ohms. Connect the speaker (+) to the left channel (+) and the speaker (-) to the right channel (-). Note: Bridged channels are not stable at 2 ohms.
Check the "Input Mode" switch. If you only have 2 or 4 RCA cables connected, ensure the switch is set to "2 Ch." or "4 Ch." This internally routes the signal to all 8 channels so you don't need Y-adapters.
This is "Low-Voltage Protection." The XDM800/8 draws significant current. Ensure you are using 4-gauge 100% Copper (OFC) wire. If your ground is to a thin or painted metal surface, the voltage will drop and trigger a shutdown.
Yes. The "XDM" series is dual-purpose. It features marine-grade coated circuit boards to prevent corrosion from humidity. However, it is not waterproof—it must be mounted in a dry location away from direct water spray.
Set the "Filter Mode" to HP (High-Pass). Turn the dial to approximately 80Hz. This protects your 6.5" speakers from deep bass frequencies that cause distortion and potential damage at high volumes.
The HD-RLC knob (sold separately) only controls the levels for the specific channel bank it is assigned to via the "Remote Level" switch. Ensure the switch for each channel pair you want to control is toggled to "On."
The XDM800/8 features Signal Sensing. Set the "Turn-on Mode" switch to "Offset" (for factory head units) or "Signal" (for standard audio). This wakes the amp up automatically when it detects music on the input wires.
