U1-1500 - Designed & Engineered in the USA


The U1-1500 amplifier provides a power for loud daily driver and non-competition music demo systems! These 1500 W full-range amplifiers are powerful, stable, and take up very little space.

The U1-1500 is a deceptively small dynamite stick of a amplifier. Even smaller than many multiple channel amplifiers, the U1-1500 fits under seats and in other discrete mounting locations.

Working on a build in a boat, UTV, or single cab pickup? Consider the U1-1500 Utility Series Amplifier. It can yield 1500 W RMS of full-range signal at 1 ohm.

This small-scale titan measures a minute 6.8” x 8.9” x 2.5”. Smaller than a shoe box, your new U1-1500 is perfect for driving a pair of HDS2.2 Series Subwoofers, any single HDS3.2 Series Subwoofer, and even an HDX3 Subwoofer with the right enclosure and electrical charging system upgrades.

For an amp the size of your granny’s King James Bible, it packs a hell of a punch.

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.
