Rockford Fosgate: PM400X2 - 2-Channel Class-A/B 400 Watt Marine/ Sports Amplifier

A versatile amp for variable conditions

Rockford Fosgate designed their PM400X2 2-channel amplifier for marine, motorcycle and powersports applications. This rugged, versatile amp can drive a pair of coaxial speakers, a set of component speakers, or a subwoofer.

Built tough for outdoor adventures

Using a Class AB design, the PM400X2 delivers outstanding performance from a compact package. It's built to stand up to outdoor life, too, with conformal-coated circuitry that withstands moisture and dirt and stainless steel hardware that won't succumb to corrosion. Rockford Fosgate also uses the innovative Maximum Efficiency Heat Sink Application (MEHSA3) construction process, which yields up to five times better heat transfer than traditional mounting techniques. As a result, this amp will rock out without overheating, even when tucked into a compact space.

The PM400X2 uses Rockford Fosgate's CLEAN level setting technology, so there's no more guesswork while setting your gain levels. Easy-to-see LED indicators identify clipping so you can set your amp up for maximum performance while eliminating distortion.
