Description

JL Audio XDM400/4 : 4ch x 75W/100W Marine Grade Amplifier @ 4Ω/2ΩXDM Series Four Channel Class D Marine Grade Amplifier, 100 Watts x Four Channels @ 2 Ohm or 75 Watts x 4 Channels @ Four Ohm. The ultra compact XDM400 4 packs a serious full range punch, generating a whopping 100 watts to each of its four 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

XDM-Series Four-Channel Class-D Marine-Grade Amplifier, 100-Watts x Four-Channels @ 2-Ohm or 75-Watts x 4-Channels @ Four-Ohm.

The ultra-compact XDM400/4 packs a serious full-range punch, generating a whopping 100-watts to each of its four 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 XDM400/4 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.

Combine the XDM400/4 with our XDM600/1 monoblock to build a stunning 1000W amplification system to power four satellites and a subwoofer... and fit the whole thing under a seat or deck. Or, use the XDM400/4 by itself to power two satellites, plus a subwoofer. 

The XDM400/4 includes a 12dB / 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 50-500Hz. 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 all amplifier channels or just the rear channels directly from the driver's seat or cockpit.

Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.

Neck came frayed/cut
Size: Large, Color: White
Poor quality. The collar/neck area was cut up/frayed. Never had a chance to return this shirt in the allocated amount of time. Guess we have an expensive rag.

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.
