Description

The SoundQubed U4-500 multichannel full-range amplifier provides ample power for UTV, boats, touring motorcycles, dune buggies, and other adventure craft! These full-range amplifiers are powerful, stable, and take up very little space. Because of the small form factor, you can run a sub, mids, and highs from one amp when space is at a premium.

SoundQubed U4-500 Specifications:

• 1-ohm stability
• Daisy chainable with pass-through channel
• Full-range versatility
• Very high, cost-effective power output ($/Watt)
• Small form factor

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, the U4-500’s are ideal for very loud outdoor PA builds and speaker arrays. Bridging 2 channels at a 2 ohm load yields about 1200 W RMS for enough power to drive a serious subwoofer.

For daily driver vehicles with a standard speaker configuration, the Q4-150 coupled with an S Series monoblock will give you a more appropriate amount of power.

Amplify Your Adventure

Let’s look at a simple system built around a U4-500 (given the appropriate charging upgrades). Channels 1 and 2 each power a separate pair of QP-MR6.5 midrange woofers. Bridging channels 3 and 4 puts out around 1200 W RMS at a 2 ohm load. That’s plenty of power for a HDS3.210 or HDS3.212 subwoofer. With 500 W RMS per channel, there are plenty of options to amplify your adventure.

Make sure your charging system is up to the challenge of powering a full-range amplifier. We do not recommend running the U4-500 on a stock electrical charging system. Upgrading your alternator, wiring, and battery will each help avoid damaging drops in voltage and/or current.

The U Series Amplifiers require between 12-14.8 V from a 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. Powersport battery upgrades are available in various designs that give you added juice with limited space in mind.

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.
