SKU: PM400X4-EPR
BRAND: Rockford
This is a 400 Watt 4-channel amplifier with high dynamic power using Class-A/B technology and a conformal coated pc board designed for motorsport and marine applications.
This is perfect for 4-way front-stage/rear-fill or 3-way front-stage/subwoofer systems. Simply drop a pair of component speakers on the front channels and subs on the rear and BOOM - you got "The PUNCH." With its flexible design, the PM400X4 is an excellent amplifier choice for virtually any vehicle.
