The 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.
Made for Music
Unlike our monoblock amplifiers, Utility Series amplifiers will drive the full frequency range of music to more than just subwoofers. This 1 ohm stable multichannel full-range amp powers subs, mids, and highs for those who like to play hard.
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.
