Smart Integration for Modern Vehicles

The Next-Gen S-Series Amplifiers introduce a new selectable remote turn-on circuit with a three-position switch, ensuring the amplifier powers on and off precisely when it should. This intelligent design is essential for today’s advanced vehicle electronics, allowing seamless integration with both factory and aftermarket systems for a hassle-free, reliable setup.

  • Hooked up my rear and front door speakers running at 4 ohms into the amp. This tiny amp is pushing the speakers easily without any fuzzy sound. Much power from a Class D amplifier!

  • If you're looking for a small but mighty amp, this is it. Clean sound, plenty of power, and has flexible setup options. The clarity and punch it delivers make my system come alive.
