SoundQubed U4-500 Multichannel Full-Range Amplifier

The SoundQubed U4-500 Multichannel Full-Range Amplifier is the perfect solution for those seeking ample power in their UTV, boats, touring motorcycles, dune buggies, and other adventure craft! This compact and powerful amplifier takes up minimal space while providing exceptional performance.

Unlike monoblock amplifiers, the U4-500 is designed to drive the full frequency range of music, making it ideal for those who like to play hard. With its 1 ohm stability, this multichannel full-range amp powers subs, mids, and highs, delivering a dynamic and immersive audio experience.

The U4-500 offers versatile filtering and crossover settings, allowing you to power and tune a variety of system designs. Its high output and small footprint make it perfect for outdoor PA builds and speaker arrays that require a loud and clear sound.

If you're looking to drive a serious subwoofer, bridging two channels at a 2 ohm load yields up to 1200 W RMS of power. However, for daily driver vehicles with a standard speaker configuration, we recommend pairing the U4-500 with an S Series monoblock amplifier to achieve a more appropriate power level.

Please note that the U4-500 requires significant charging system upgrades to operate optimally. It is essential to upgrade your alternator, wiring, and battery to avoid damaging drops in voltage and current. We recommend using AGM 12V batteries or lithium batteries that don't require high voltage to ensure a reliable and efficient power supply.

It's important to mention that the U Series Amplifiers do not have an IP rating, so submersion and saltwater environments should be completely avoided. While the circuit board has a water-resistant coating to protect against humidity and incidental moisture, the casing does not have sealed edges.

With its 1-ohm stability, daisy chain capability, full-range versatility, high power output, and compact form factor, the SoundQubed U4-500 Multichannel Full-Range Amplifier is the perfect choice for anyone looking to amplify their adventure. Just make sure to upgrade your charging system before installation to ensure optimal performance and avoid any potential damage.
