Want more from your car stereo? “U” got it!

The SoundQubed Utility Series full range amplifiers provide massive 1-ohm stable power from a tiny footprint. You’ll also enjoy having space in the vehicle for enclosures, speakers, and cargo. With Utility Series amps, you can build the music demo build of a lifetime!

What makes the U-Series different

Unlike a monoblock, a full range amplifier drives more than just your subwoofers. They’ll drive the full frequency range of music for mids and highs as well. With high and low pass filters, U-amps are tunable for a variety of systems.

You should not consider using Utility Series amps for SPL competition burps*. Also, you should never wire speakers below 1 ohm with a full-range amplifier.

Because of their high output, the U Series are ideal for “groundpounder” music demo systems.

The Fine Print:

Inadequate charging systems will destroy a full-range amplifier.
If you connect the Utility series to stock electrical charging systems, you will damage the amp and void the warranty.

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. Likewise, lithium batteries — that don’t require high voltage — are a good choice when running a full-range amp.
