If you’re chasing tight, hard-hitting bass without overcomplicating your setup, the R2-500X1 mono subwoofer amplifier is exactly what you need. Built with efficient Class-D topology, it delivers clean, reliable power to your sub while keeping heat and strain low. Add in its cast aluminum heat sink, and you’ve got an amp that stays cool even when the bass is anything but. Certified CEA-2006 and CE compliant, this thing doesn’t just sound good—it’s built to perform with real, verified power you can trust.
This amp makes integration into almost any system super easy. With high-level input capability and balanced differential inputs, you get clean signal flow no matter your setup. Got a newer vehicle with RAP (Retained Accessory Power)? No problem—the auto-sense bypass switch has you covered. Tuning is just as smooth, thanks to the top-mounted control panel and C.L.E.A.N. setup feature, making installation and dialing in your system way less of a headache and way more plug-and-play friendly.


When it comes to sound shaping, the R2-500X1 gives you full command. Fine-tune your bass with continuously variable Punch EQ, adjust crossover points with fully adjustable 12 dB/octave high and low pass Butterworth filters, and protect your lows with a variable infrasonic filter. Want more control on the fly? The included RLC remote level control puts bass adjustment right at your fingertips. And with built-in safeguards like short circuit protection, over current protection, and rollback protection, you can push your system hard with confidence knowing it’s protected every step of the way.

Got this amp in without a sweat ! Easy to set up, and I love how I could tweak them gains without stressing it. Highly recommend this little beast. It's got enough power to make my F-150 shake.This amp's a real punch-packer for its size! Paired it with a passive 10-inch sub, and it sounds awesome. Runs cool but packs a punch.
