Overview

The Earthquake XJ-300ST stereo amplifier packs more power and flexibility than most amplifiers. With an unimposing miniature size and almost unreal amounts of cool running power, this advanced Class J amplifier is the installer’s go-to dream. With the XJ-300ST, connecting a third speaker between the two main channels is possible. This matrix mono channel plays the combined content of both channels, which is extremely useful for powering two satellites and a subwoofer.
