Review: Great amp, with awesome sound and definite value for the money - Sounds really better than expected. Looks great and inconspicuous. I have mine wired at 2ohms. It holds stable with no drain and no overheating. Easy to connect and the auto on/off feature is great. You'll really enjoy this amp. It provides a great sound over stock any day. And if we're being honest, i actually bought 2!
Review: Awesome Amp - Really great amp for the money. Good amount of adjustability, produces good sound and is plenty powerful. The bridging feature and selection between 1, 2, or 3 channels makes it very versatile. Doesn’t get very warm powering (2) 6.5” door speakers and a Kicker 8” woofer.

### ⭐⭐⭐⭐⭐ Fantastic Amplifier!!
*by D***D on October 20, 2025*

I love the power and performance of this amplifier. It fits nicely on the ledge in my trunk and looks very professional. I purchased this Pioneer Amplifier in August 2019 along with an in-dash Pioneer stereo, speakers, and a 10-inch subwoofer. I had it installed professionally at Best Buy, which I highly recommend. My entire system has performed flawlessly for just over five years. My Pioneer 4-channel amp is truly a game changer.
