Rockford Fosgate T400X4AD

Compact Power, Maximum Output
The Rockford Fosgate T400X4ad Power 4-channel amplifier delivers an astonishing 400 watts of power in a highly compact design. Measuring just 1.6” x 4.3” x 8.3”, this amplifier packs more power per square inch than any other model in its class. Perfect for tight spaces in small vehicles, trucks, motorcycles, and UTVs, the T400X4ad offers outstanding performance without taking up valuable space.

Constant Power Technology for Consistent Performance
Utilizing proprietary Constant Power technology, the T400X4ad ensures consistent, high-output power across all impedance loads. Whether you're operating at 4-ohms, 2-ohms, or in bridged mode, the amplifier delivers up to 25% more power compared to conventional amplifiers. This makes it ideal for powering full-range speakers in various vehicle setups while maintaining optimal performance, regardless of the impedance load.

Advanced Features for Superior Sound Quality
The T400X4ad is equipped with a host of advanced features, including high-level auto turn-on, CLEAN circuit input/output clip detection, and an onboard Punch EQ with a +18dB boost at 45Hz for enhanced bass response. The 12dB/octave Butterworth crossover ensures smooth, precise control over your audio system's frequency output. Known for its Rockford Fosgate durability and quality, this amplifier is backed by a full 2-year warranty, providing peace of mind for years of exceptional performance.
