A powerful, versatile amp for your boat
Rockford Fosgate designed their PM400X4 4-channel amplifier for marine and Powersports applications. It'll power systems with front and rear speakers, it'll drive a couple of subs in 2-channel mode, or you can switch the amp to 3-channel mode to power a set of speakers and a subwoofer.
Built tough for life on the water or off the road
Using a Class AB design, the PM400X4 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 tight space.
The level setting made easy
The PM400X4 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.
