JL Audio XDM400/4 4 Ch. Class D, Full-Range Car/Marine Amplifier, 400 W

Model: XDM400/4

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 1000 W 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 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 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.

Makes delicious iced coffee!
Flavor Name: Vanilla, Flavor Name: Vanilla
Im someone who likes their coffee to actually taste like coffee and I love this syrup. I’ve been making iced coffee at home almost daily lately, and this vanilla syrup is the only one I keep reaching for. The flavor is smooth and sweet without tasting artificial, and it actually tastes good in iced drinks instead of getting lost in the coffee. The pump also makes it really easy to use without the sticky mess. My current go-to drink: • 2 pumps vanilla syrup • Double espresso pod • Pour over lots of ice • Splash of almond milk • Finish with brown sugar creamer Your bank account will thank me!!!

Syrup is excellent, the pump is dramatic
Flavor Name: Vanilla
I am marking 5 for the syrup itself, my favorite syrup. In regards of the pump, a little too dramatic for me and it will go everywhere. I would rather pour the syrup, including I found the pump will leak and there was a ring of syrup around the base of the bottle. Perfect for a coffee shop, but not for a basic kitchen....but I am picky about syrup splattering because the sugar ants are a nightmare.

GREAT GRAPE FLAVORED AND INCREASED ENERGY
Set name: Welch's Grape
I have tried the competitor’s grape flavored versions. This is by far the best grape flavored energy drink. It gives you the increased energy level you’re looking for without making you feel “fidgety.” Highly recommend this energy drink for its effectiveness and flavor!

Green Apple is the best!
Set name: Warheads Sour Green Apple
Love these, I am subscribed for every two weeks, they last me one a day at work until the next shipment. Yay! Green sour apple is just the best. It’s slightly sour and refreshing. I work graveyard and stay awake all night with one of these. Super effective, great value for the money since I’m getting them cheaper this way than buying one a day at the convenience store next to my house. They’re sugar free but use sucralose, which is wannabe sugar but still, I’d say better for me (pre-diabetic) than real sugar.

Red Berry Drink
Set name: Sour Patch Kids Redberry
I drink one of these red cans when I get to the shop in the mornin. The taste reminnd me of the candy my kids liked when they were small. It has a sour kick at first but a sweet taste comes next in my mouth. I feel awake after I finish the can. My focus stays sharp while I work on the mashines for a few hours. I do not feel jitters in my hands or my chest like I do with some coffee. The liquid has no color which is fine with me because it does not stain my teath. I keep the pack in the small fridge in the garage to keep them cold. It is a good choice for days when I have a lot of heavy labor to do. My brother tried one and he thought the flavor was tart but I think it is right. I do not feel a crash when the afternoon comes. It is a way to get energy for my shift. I like that the cans are tall and hold much to last a while. My wife says I look alert when I use them before our walk.
