Don’t let the size fool you, the PRV Audio MDX400.4 is built to bring serious performance to your system. Delivering 400 watts RMS across four channels, this amp gives you strong, clean full-range sound that easily upgrades any setup. Whether you’re running door speakers or a full system, you get 4 x 100W RMS at 2 ohms or 4 x 70W RMS at 4 ohms, giving you the flexibility to dial in your power exactly how you want it.
This amp is made for real-world installs where versatility matters. You can run it in 4, 3, or 2 channel configurations, and when you need more punch, bridge it to push 2 x 200W RMS at 4 ohms. That means fewer amps, less clutter, and more control over your build. The ultra-compact mini chassis makes it easy to install just about anywhere, perfect for tight spaces like motorcycles, ATVs, or custom builds where every inch counts.


Engineered with efficient Class-D Brazilian technology, the MDX400.4 delivers impressive output without putting unnecessary strain on your electrical system. It’s packed with surface mount components for durability and better vibration resistance, so it holds up even in demanding environments. A built-in cooling fan and heavy-duty heatsink keep temperatures in check, ensuring consistent performance when you push it hard. And at just 0.87 lbs, it’s lightweight without sacrificing strength, making it a smart choice for any high-performance audio setup.
