Class A/B Throughout

Zapco opted to use Class A/B architecture throughout their 4-channel ST-4XII car audio amplifier. They did this because of the strong output and excellent sound quality that Class A/B offers in comparison to the other classes that exist. Teamed up with Zapco’s experienced sound engineers, you’re looking a finely-crafted amplifier.

Full-range Outputs on All Channels

Are you setting up a killer audio system and you’re in the market for an amplifier that delivers strong, reliable full-range power through 4 channels? Zapco’s ST-4XII amplifier is the perfect solution for you. If you end up changing the configuration of your audio system, you can simply flick some switches to engage the on-board high-pass and low-pass filters.

4/3/2-Channel Configurations

The ST-4XII allows you to configure it in a few different ways so as your system evolves, so can your amplifier. It can be hooked up in a traditional 4-channel way to power the speaker system in your car or you bridge the four speaker outputs into a 2-channel mode (at 4 ohms) to deliver stronger power to high-performance front speakers. Lastly, if you wanted to power front speakers and a small, efficient subwoofer, you’re able to do this, too, in 3-channel mode.

Looking for a different amplifier configuration? The Zapco ST-X-series is also available in a high-power 4-channel or 5-channel design.
