400 Watt Class-AD 4-Channel Amplifier

Model T400X4AD

The Power T400X4ad is an ultra-compact, high efficiency 400 Watt 4-channel amplifier. Features multi-impedance Constant Power, input/output clip detection, top mounted controls and dual fan forced induction cooling. Perfect for hybrid, electric, small cars, trucks, motorcycles, and side-by-side UTVs.

T400X4ad

The Power T400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgate’s proprietary Class-AD technology, featuring Constant Power to produce the same output at both 4-Ohm and 2-Ohm impedances. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on. Top mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier.

Company Details

Rockford Fosgate®. It's a full sentence. It means POWER! It means ATTITUDE! Since 1973, when founder Jim Fosgate put his name on the first real piece of high performance audio equipment built for the car, nothing has been the same.
While the rest of the world was struggling with really bad fashions and shoes that were way too high, Jim Fosgate, working in his garage in Arizona, USA, figured out that an amplifier, and for that matter, a car audio system would have to be dramatically different than what people were listening to in their homes.This meant an amplifier that could run low impedance loads, which meant that it would have to run in stereo and mono simultaneously. These needs then dictated that the amplifier incorporate a MOSFET design, a small detail that was unknown in the world of audio at the time. Wrap all this "technobabble" into the single most important development of the Fosgate designs… The PUNCH EQ.punch amp
While working with a friend, Jim realized that music and the human ear had very different sonic signatures or "curves". Where the human ear had the most trouble [down in lower frequencies at lower volumes] the music made it worse.The solution has been the patented Punch EQ… the ability to add up to +18dB at 45HZ…(Bass Boost) & and/or +12dB at 20kHz (Treble Boost - this is a hinge filter active from 1kHz to 20kHz.)
That’s a lot of control! Things such as car windows, leather, road noise, and even your annoying life mate that never stops yappin'… all benefit from the musical energy that Punch EQ puts back into the system. The sound of THE PUNCH gave Mr. Fosgate’s first customers the impact that their music needed. Now… that PUNCH is the sound of Rockford Fosgate® and you can hear it in everything we make.
