T400X2AD

The Rockford Fosgate T400X2ad is one of Rockford’s most popular compact Power Series amplifiers because it delivers full-size amplifier performance in an extremely small chassis. Built using Rockford Fosgate’s proprietary Class-AD and Constant Power technology, the amp produces the same rated output at both 4Ω and 2Ω loads while maintaining excellent efficiency and low heat output.

This amplifier is especially popular in Harley-Davidson, Jeep, powersports, motorcycle, and tight-space custom installs where mounting room is limited but high clean output is required. Despite its compact footprint, it delivers 200W RMS per channel and includes dual fan cooling, C.L.E.A.N. clip detection, and flexible crossover controls.
