The Power T1000-4ad is a 4-channel amplifier that combines the sound quality characteristics of a Class-A design with the efficiency of a Class-D in one remarkable package, offering high fidelity in a full-range configuration.


The T1000-4ad combines sound quality characteristics of Class-A designs with efficiency of a Class-D in one remarkable package. Superior sound quality is possible through the implementation dynamic switching frequency control. The addition of Constant Power circuitry produces optimized output at a range of impedances. Rockford Fosgate created Class-bd for brute power to run low frequency subwoofers, and now Class-ad offers high fidelity in a full-range configuration.

Balanced Differential Inputs

Differential inputs eliminate noise picked up by signal cables.

Class AD

This technology allows the amplifier to produce more power with less current draw from the vehicle's charging system.


DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

Constant Power

Constant Power is a patented circuit topology that provides instantaneous delivery of output power over varying impedance loads.

CEA-2006 Compliant

Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.


MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.


NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.

Punch EQ2

Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.

Engineered In The USA

These Avatars are a personal signature from the Rockford Fosgate team member(s) who designed and engineered this fanatic product. This statement illustrates our commitment to being Designed and Engineered in the U.S.A.

4Ω/2Ω/1Ω Capable

Allows the amplifier to produce the same power into either a 4-ohm, 2-ohm or 1-ohm speaker load. Works with Constant Power to optimize power output at varying impedances.
