TREO Engineering once again brings "Tomorrow's Technology Today" with the all-new lineup of MSX Compact Amplifiers. The all-new TREO MSX Compact Amplifier lineup delivers full-size power to your speakers or subwoofers from the most compact amplifier chassis in the industry.

Small size does NOT mean these amps are light on features; these amplifiers come loaded with all necessary features to achieve sonic bliss in the most demanding applications. Mid-engine sports cars, motorcycles, and regular cab trucks have always been some of the most challenging mobile audio applications, and TREO MSX Amplifiers have been designed from the circuit board up to deliver audiophile sound quality and high output in these tough spots.

Some other small amplifiers can't take the heat, but TREO MSX Amplifiers have been torture-tested to guarantee nonstop operation even in twenty-first century global warming heat waves. TREO MSX Amplifiers have the heatsink capability to operate in tight confinement in vehicles from Florida to Texas to Southern California. The design is so refined these amps don't even require a fan.

High efficiency design coupled with intelligent audio filters enable these amps to draw the absolute minimum current necessary to deliver absolute aural satisfaction in today's more compact and fuel efficient vehicles. These amplifiers can even be used in motorcycles and all-terrain vehicles.

Three models are available, the class-D monoblock MSX1, the class-AB stereo MSX2, and the class-AB four-channel MSX4 (late availability).

The monoblock MSX1 delivers a punishing 350W RMS into a one ohm mono subwoofer load. A subsonic filter coupled with a selectable low-pass crossover combine with the efficient class-D design to make this one of the most efficient amplifiers ever developed.

The stereo MSX2 offers up 50Wx2 into a four ohm stereo load or 100Wx2 into a two ohm stereo load when driving two pairs of integrated or separate speakers. This compact two-channel amplifier boasts a selectable and adjustable high-pass filter that bolsters efficiency and ensures the proper notes are routed to the right speakers.

The four-channel MSX4 has all the features of the MSX2, but with four amplifier channels instead of two. Each pair of channels boasts its own independent controls for amplifier gain and for the selectable and adjustable high-pass crossovers.

The MSX1 and MSX2 share the same tiny 7in x 6-1/8in footprint and the MSX4 is only one inch longer. All three MSX Amplifier models are only 1-1/2in tall, allowing for placement in nearly any dry and solid location. All three amps share common spacing for the mounting holes so multiple MSX Amplifiers of any type can be stacked on top of one another for increased installation flexibility.

Like all TREO Engineering car audio equipment these amplifiers are based on American design and engineering and come backed with the promise to offer great sound for years to come.
