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.

    This amplifier is very amazing 👏. I’m wired down to 1 ohm and my two vxf 15’s are moving the streets you heard! I definitely recommend this series of amplifiers. Thank you again Soundqubed.

    I’m running the U1-8000 @ just under 2 ohms to a single 15″ Sundown retro Nightshade V.3 and it is throwing massive amounts of clean power to it. I absolutely love it. I’ve had many different brands of high power amplifiers and the U1-8000 is dollar for dollar, one of the best amps I’ve ever owned. For the price…there isn’t a better 8k amp out there. I own my own box building/ installation business and I’m starting to turn my customers onto Soundqubed. 5 Star Audio Solutions has your support 100% Thank you guys.

    This amplifier is a complete powerhouse. I was amazed by the power and clean sound that this amplifier puts out . There is no way to go wrong by buying anything with the soundqubed symbol on it. Just remember to upgrade your electrical before installing a amplifier that has this much power because it takes power to make power.
