The ST-X Series. Class A/B and D Amplifiers.

The Studio-X line of amplifiers from Zapco was designed specifically for today’s car audio market. The Studio-X compact chassis makes it an easy fit in any car and even in motorcycle fairings.

The square, low profile chassis also means it will be easy to trim out for a great looking installation so your system will look as awesome as it sounds. And speaking of sound...This is a Zapco amplifier and sound is what it’s all about. These are Class A/B Zapco amplifiers.

The Studio-X have the same high quality caps, op-amps, and bi-polar outputs that made the C2K and Reference series amps the industry standard for sound quality. 

Reliability? Zapco defines reliability. It’s not at all unusual to see Zapco amps moved from car to car and from generation to generation. Zapco Amps produced in the ‘90 are still being traded and bought on the internet by sound quality fans world wide. The Studio-x will be no different.
