Our take on the JL Audio MX280 4 4-Channel Car Amplifier

The MX280/4 is a compact four-channel Class D amplifier from JL Audio's MX marine line. It is small enough to tuck into tight spaces and light at about 3 pounds, with a 35A fuse and a 20 Hz to 20 kHz response. It is not rated for marine use, so it suits car and powersports installs rather than boats. Compared with larger four-channel amps it trades total output and bridging flexibility for size, and it cannot be bridged, which limits it to four separate speakers.
