I understand that this amp requires specific significant charging upgrades. I have already made these upgrades or will do so before attempting to install and operate this amplifier.

I am responsible for damage to the amp caused by an inadequate electrical charging system.

The U1-1500 amplifier provides the power you need for loud daily driver, non-burp competition, and demo systems! This 1500 Watt, full-range amplifier is powerful, stable, and takes up very little space.

Working on a build in a boat, UTV, or single cab pickup? Consider the U1-1500. It’s ideal for under-seat installations, yielding 1500 W RMS of full-range signal at 1 ohm with a form factor smaller than a shoebox.

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

Made for Music

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.

Water and electricity don’t mix

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.
