The Studio-X line of Amplifiers from Zapco was designed specifically for today’s car audio market. The ST-X amplifiers are the smaller lighter amps you need for today’s smaller lighter cars. But with the Zapco ST-X amps, smaller doesn’t mean weaker or softer. 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 1O, 2O, or 4O 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. 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. These amps are built to last.

Great Amp Got here fast and the Amp is great Zapco makes fantastic amps and I happy yo see that is still the case. The class D works well for bass but not for miss and tweets.

Very nice amp! I went from a Kenwood Kac-9105D to this amp (Zapco ST-850) and my two 12″ kicker comps (c124) sound so much better! The Kenwood wasn’t crap at all!!.. but for some reason this Zapco just feels like the music has more soul, definition….. heart!! If you can afford it… Get this! The insides of the amp is gorgeous!!! Zapco should have made it transparent! As long as Zapco keeps up the quality and doesn’t skimp on power ratings, I’ll be a fan for a LONG time!
