1000-Watt RMS Mono Block Class D Amplifier

Made for Power, Built for Bass

The THUNDER1000.1 is a high-powered 1000-watt RMS amplifier designed to be installed in almost any vehicle due to its small chassis size. Its power capability makes it a perfect choice for running single or multi-woofer sound systems without worrying about compromising bass output or quality.

1000-Watt RMS Mono Block Class D Amplifier

Technologically Advanced

This amp features a high-efficiency Class D circuit design chosen for its ability to produce high output power while minimizing power loss to heat build-up. It’s this capability that makes it perfect for driving woofers to their limits and delivering that vehicle shaking bass you want.

It’s not just the circuit type that makes this amp tick, but also the parts used and how they are installed. We use surface mount technology to help create the compact design of the amplifier and improve its reliability and resistance to vibration. High grade components are chosen for the quality and to ensure the amplifier delivers maximum power output when you need it.

In addition to the circuit design, we’ve also added the features you need to fine tune your system sound such as the built-in variable low pass crossover, selectable bass boost circuit and variable subsonic filter. Additionally, we know how important the speaker and power connections are to a properly working sound system. This is why we use set-screw style terminals to provide the most secure connection possible which minimizes any power loss while delivering all the power to the amplifier and to the speakers.

Remember The Amp Kit

Remember, you cannot install an amplifier without an amplifier kit. MTX recommends using a ZN5K-04 to power the THUNDER1000.1.
