U1-3000 - Designed & Engineered in the USA


The 3000 W Full-Range Utility Series Amplifiers are great for demo builds of all sizes. The U1-3000 can drive any pair of HDX3 Series Subwoofers and saves room in your build!

Enjoy the compact size and advanced board design for this 1Ω stable, 3000 W full-range amplifier in your daily driver with upgraded electrical or smaller demo build vehicle.

Unlike our monoblock amplifiers, Utility Series amplifiers will drive the full frequency range of music to more than just subwoofers. As a 1-ohm stable full-range amp, you can power subs, mids, or highs. The only limitation is the power handling and impedance of the speakers you’re driving.

Versatile filtering and crossover settings let you power and tune a variety of system designs. Because of their high output and small footprint, Utility Series full-range amplifiers are ideal for extreme “ground pounder” daily driver setups, or strictly music demo systems. On the other hand, Utility Series amps can’t handle competition burps.

Knowing the specs of your charging system is crucial to running a full-range amplifier. We do not recommend running the Utility series on stock electrical charging systems. Alternator upgrades, the Big 3 wiring upgrade, and added battery capacity will help avoid damaging drops in voltage and/or current. The U Series Amplifiers require between 12-14.8 V from the charging system. AGM 12V batteries are a good fit. Lithium batteries that don’t require high voltage are also a good choice when running a full-range amp.

U Series Amplifiers do not have an IP rating. You should completely avoid submersion and/or saltwater environments. The amp casing doesn’t have sealed edges to keep water out. However, the circuit board has a water resistant coating to protect against humidity or  very small amounts of incidental moisture.
