T400X2ad

The Rockford Fosgate T400X2ad is an exceptionally compact and powerful 2-channel amplifier from the high-end Power Series. Thanks to its innovative Class AD technology, it combines high output power with efficient operation and a minimal footprint. Despite its compact dimensions, the amplifier delivers an impressive 2 × 200 watts RMS at 4 or 2 ohms, as well as 400 watts RMS in bridge mode.

The built-in Constant Power technology ensures consistent output power across a range of speaker impedances. This makes the T400X2ad ideal for high-power front-channel systems, high-quality speakers, or a bridged subwoofer.

With adjustable high- and low-pass filters, the built-in Punch EQ tone control, and the convenient C.L.E.A.N. technology for precise level adjustment, this amplifier offers a wide range of options for optimal integration into your existing audio system.
