Super Small Multi-Channel
The new SS amplifiers are the latest in high speed, high current class D designs offering high power and superior sound quality in compact footprints. The classic DD AUDIO style heat sink is used in this upgrade for max cooling with 50% more side wall thickness than industry norms and extra long fins to increase surface area. All major components have been upgraded; higher current mosfets and output devices, increased power capacitors, a more powerful transformer, plus improved venting and PCB with twice the thermal capability.These new high-end mini amps are state of the art, no compromise designs yielding the best sound with unparalleled power to size ratio. The transformation is not only tangible, but audibly apparent.The SS4.500 is a 4 channel amplifier delivering a minimum of 125 Watts per channel from a mere 30 square inch footprint. This versatile, high speed, class D design can drive full range components and subwoofers through selectable high pass and low pass crossovers. These super small amplifiers are the ultimate combination of precision sound quality and installation ease.
For the SS Series the main design focus was to pack as much full-range stereo output capability as possible into as compact of a chassis as possible. We utilized discrete circuit class D technology for ultra low distortion levels that rival class AB designs. The resulting amp is capable of driving multiple driver mid-range and tweeter arrays while consuming less current, taking up less space and delivering more power.

Ultra-Compact 400W 4-Channel Amplifier Class-AD, Constant Power, C.L.E.A.N. Clip Detection, and a 2/4-Channel Input Switch for Flexible Integration.
Product Overview
The Rockford Fosgate Power T400X4AD is a 400W 4-channel amplifier built on the same Class-AD platform as the T400X2AD delivering high efficiency in an ultra-compact chassis purpose-built for hybrid and electric vehicles, small cars, motorcycles, and side-by-side UTVs. While the T400X2AD handles two channels, the T400X4AD extends this to four channels, making it the appropriate choice when all four speaker positions (front left, front right, rear left, rear right) need amplification from a single compact unit.
A 2/4-channel input switch is a key addition over the 2-channel model allowing the amplifier to accept either a full 4-channel input from four RCA connections or a 2-channel input that is internally split to drive all four output channels. This simplifies integration with headunits that offer only a 2-channel RCA output while still delivering amplification across all four speaker positions. High-level inputs with auto turn-on, Remote-Out, C.L.E.A.N. clip detection, top-mounted controls, dual fan cooling, and 4Ω bridged capability complete the feature set shared with the T400X2AD.
Key Specifications

Features & Benefits
4-Channel Output for Full Speaker Coverage — Amplifies all four speaker channels (front and rear left/right) from a single compact unit — providing a full-vehicle speaker upgrade without requiring a second amplifier or a larger chassis.
2/4 Channel Input Switch — A key practical addition over the T400X2AD. In 2-channel mode, a single stereo RCA input is split internally to drive all four output channels — ideal for head units that offer only a 2-channel preamp output or systems where running four RCA cables is impractical. In 4-channel mode, discrete stereo front and rear inputs allow independent level control across the front and rear channels.
Class-AD Technology — Ultra-Compact High Efficiency — The same Class-AD topology as the T400X2AD, delivering high efficiency in a compact chassis suited to hybrid vehicles, electric vehicles, UTVs, motorcycles, and small cars where a conventional full-size 4-channel amplifier will not fit.
Constant Power at 4Ω and 2Ω — Maintains the same output wattage at both 4Ω and 2Ω speaker loads — consistent amplifier performance regardless of whether 4Ω or 2Ω speakers are fitted across the four channels.
High-Level Inputs with Auto Turn-On — Connects directly to factory head unit speaker outputs without a remote turn-on wire — essential for modern OEM systems, hybrid and electric vehicles, and any installation where a conventional RCA and remote output is unavailable.
Remote-Out via High-Level Input — When activated by high-level auto turn-on, the Remote-Out provides a 12V trigger for downstream accessories — enabling a subwoofer amplifier or other accessories to be activated in parallel without a remote wire from the head unit.
C.L.E.A.N. Input/Output Clip Detection with LEDs — Monitors both input and output stages for clipping during gain setup, with separate LED indicators for each stage. Removes the guesswork from gain setting — the single most important step for maximising sound quality and protecting speakers and the amplifier.
Top Mounted Controls — Gain, crossover, and C.L.E.A.N. indicators are all accessed from the top of the amplifier, making adjustments and visual checks possible without removing the unit from its mounting position.
Dual Fan Forced Induction Cooling — Active cooling manages heat in confined mounting spaces common to compact vehicle and UTV installations where passive cooling alone is insufficient.
Dual Extruded Heat Sinks with Real-Time Thermal Sensing — Passive and active thermal management in combination — the 3-stage thermal lock extrusion provides staged protection against sustained overload.
4Ω Bridged Capable — Any pair of channels can be bridged to deliver higher output to a single 4Ω load — adding subwoofer drive or high-power speaker capability to the 4-channel configuration.

8 AWG amplifier wiring kits
Rockford Fosgate or aftermarket 4-channel RCA cables
Frequently Asked Questions
What does the 2/4 channel input switch do?
In 2-channel mode, a single stereo (2-channel) RCA input is internally distributed to drive all four amplifier output channels — useful when the head unit has only a 2-channel preamp output. In 4-channel mode, discrete front and rear stereo inputs are used, allowing independent front/rear level control. This makes the T400X4AD compatible with a wider range of head units without requiring additional signal processing.
How does the T400X4AD differ from the T400X2AD?
Both amplifiers share the same Class-AD platform, feature set, and wattage. The T400X4AD provides four output channels versus two, and adds a 2/4 channel input switch. The T400X2AD includes PLC2 remote compatibility — confirm whether the T400X4AD supports PLC2 remote operation with Rockford Fosgate if this is a requirement.
How does the high-level auto turn-on work with a factory system?
The high-level inputs accept signal from factory head unit speaker outputs and activate the amplifier automatically when audio signal is present — no remote turn-on wire is required. The Remote-Out then provides a 12V trigger for a downstream subwoofer amplifier or other accessories.
What does C.L.E.A.N. clip detection help with during installation?
C.L.E.A.N. (Circuit Level Evaluation And Normalisation) monitors both the input and output stages for clipping, with LED indicators for each. During gain setup, the LEDs identify when the signal clips — allowing the gain to be set at the maximum clean level. Correct gain structure is the most effective way to protect speakers from distortion damage and maximise sound quality.
Can the T400X4AD be used in a bridged configuration?
Yes. Pairs of channels can be bridged to deliver higher output to a single 4Ω load — for example, bridging channels 1 and 2 for a front subwoofer or a single high-output speaker, while channels 3 and 4 continue to drive rear speakers in standard stereo configuration. Confirm the bridged power output at 4Ω with the official Rockford Fosgate datasheet.
