The Rockford Fosgate M2-300X4 Class-D Marine/Powersports Amplifier is made for enthusiasts who want serious power in a tough, no-nonsense package. With a flexible 4-channel design that can also run 3-channel or bridged 2-channel setups, it adapts easily whether you are building a full system or upgrading step by step. It is the kind of amplifier that fits into almost any plan without limiting your creativity.
This amplifier delivers CEA-2006 verified output with 50 watts RMS across four channels at 4 ohms, giving you consistent and measurable performance you can rely on. It is not just about numbers, it is about how clean and controlled the sound stays even when you push it. The balanced differential inputs help strip away unwanted noise so what you hear is pure, detailed audio instead of interference or distortion.


The M2-300X4 is built for real-world abuse with a conformal-coated PCB and UV-resistant marine-grade construction that stands up to moisture, corrosion, and vibration without breaking a sweat. Inside, MEHSA-4 thermal management keeps temperatures under control while NOMAD protection technology constantly monitors system conditions to protect your gear without killing performance. Add in the CLEAN gain setup system, independent channel tuning, and flexible crossover controls, and you get an amplifier that is not just powerful but also incredibly easy to dial in exactly how you want it.
