Zapco ST-850XM II 850 watt Mono Class D Amplifer
With the ST-S amps you get all the power and sound quality you expect from Zapco. 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. The Class A/B Zapco amplifiers for mids and highs havce the same high quality caps, 5532 op-amps,and bi-polar outputs that made the C2K and Reference series amps the industry standard for sound quality. For the bass, the ST-X mono Class D amps come in 5 power levels so whether you’re running a 1Ω, 2Ω, or 4Ω load, the ST-X bass amps are the right choice for the power for the right price, for your system, in your car.
Reliability? Zapco defines reliability. It's not at all unusual to see Zapco amps moved from car to car and from generation to generation.
