DC Audio 1.2K Competition Series Amplifier – 1,200 Watt Monoblock

Serious Bass Starts Here. Competition Power. DC Audio Performance.

Big bass doesn't always require the biggest amplifier. The DC Audio 1.2K Competition Series Amplifier delivers the power, performance, and tuning flexibility serious car audio enthusiasts demand in a versatile 1,200-watt monoblock design.

Engineered to produce 1,200 watts RMS at 1 ohm and 14.4 volts, the DC Audio 1.2K provides the power needed to drive high-performance subwoofers with authority. For systems operating at higher voltage, this amplifier is capable of producing up to 1,500 watts RMS at 16.0 volts.

Whether you're upgrading a factory audio system, building a powerful daily-driven bass setup, or getting started in SPL competition, the DC Audio 1.2K offers serious performance with room to grow.

And when you're ready for more power, its master/slave linking capability allows you to strap two amplifiers together for up to 3,000 watts RMS at 2 ohms and 16.0 volts.

DC Audio – Get On Our Level.

1,200 Watts RMS of Competition-Grade Power

The DC Audio 1.2K is designed to deliver reliable, high-output performance for demanding subwoofer applications.

Producing 1,200 watts RMS at 1 ohm and 14.4 volts, this competition monoblock amplifier provides substantial power for daily-driven car audio systems and entry-level SPL competition builds.

When operated at 16.0 volts, the DC Audio 1.2K can produce up to 1,500 watts RMS at 1 ohm, giving enthusiasts additional output potential with a properly designed electrical system.

Its 1-ohm-stable design provides flexibility when selecting and wiring subwoofers, making it an excellent option for a wide range of car audio installations.

Link Two Amplifiers for Up to 3,000 Watts RMS

One of the biggest advantages of the DC Audio 1.2K is its ability to grow with your system.

With master/slave amplifier linking, two compatible DC Audio 1.2K amplifiers can operate together in a strapped configuration.

At 16.0 volts, a linked pair is rated to produce up to 3,000 watts RMS at a 2-ohm combined load.

This allows you to start with a single 1.2K amplifier and expand your system later without having to replace your original amplifier.

Whether you're upgrading to larger subwoofers or building a more powerful bass system, the DC Audio 1.2K gives you the flexibility to take the next step.
