Default JL Audio MX280/4 Marine/Motorsports Amplifier

JL Audio MX280/4
Used, good. Missing on mounting ring
$140 Shipped CONUS:

Up for sale is a lightly used MX280/4 4-channel amplifier. Fully-tested and found to be fully functional. Missing 1 mounting foot.

MX280/4
4-Channel Class D Full-Range Amplifier, 70 W x 4 @ 2 Ω / 50 W x 4 @ 4 Ω - 14.4V

Engineered specifically for powersports applications, the 4-channel MX280/4 amplifier employs our high-speed NexD™ switching design to deliver plenty of clean power, without straining charging systems. Its tiny, cast aluminum chassis is highly resistant to corrosion, with an IPX6 water-resistance rating, making it perfect for motorcycles, ATV's or other utility vehicles.
Generating a solid 50W x 4 into 4 ohms (14.4V, 1% THD), the MX280/4 is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a potent 140W x 2 into 4 ohms.
Other features include independent front and rear crossovers with selectable full-range, high-pass or low-pass filter controls and a dual-range input section that accepts a wide range of input voltage levels, from line-level all the way to high-power speaker level signals.
This amplifier features a black powder-coated finish, a gasketed cover for the controls and stainless steel hardware for durability.

I'm pretty sure they do. I've never known a JL amplifier that when tested did not do rated power.

It outperformed the ratings by 40% at 4 ohms and greater than 30% @ 4 ohms bridged.
