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.

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.

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.

100 Watts × 4 Channels at 2Ω Compact 4-Channel Amplifier for Front/Rear Systems and Front Stage with Rear Subwoofer.
Product Overview
The Rockford Fosgate Power T400-4 is a 4-channel amplifier delivering 100W into each of its four channels at 2Ω confirmed by Rockford Fosgate making it suitable for a full 4-way front and rear speaker system or a front stage and rear subwoofer configuration. The compact chassis with Dynamic Thermal Management is specifically designed for under-seat or space-constrained installation locations that full-size 4-channel amplifiers cannot accommodate.
Unlike the Class-AD T400X4AD which prioritises ultra-compactness for hybrid vehicles and UTVs the T400-4 is a full-featured conventional design with a MOSFET power supply and output stage, 4-gauge power and ground connectors, a 24dB/octave crossover, and a 2/4 channel input switch for flexible headunit integration. It is the choice when confirmed 100W per channel at 2Ω output is the primary specification requirement, and when the installation allows 4-gauge wiring for maximum power delivery.

Features & Benefits
100W × 4 Channels at 2Ω — Confirmed Power Specification — Unlike many amplifier listings where per-channel power at a specific impedance is absent, Rockford Fosgate confirms 100W per channel into 2Ω on the T400-4. This gives the system designer a concrete figure to work with when matching the amplifier to 2Ω speaker loads. Power at 4Ω and bridged mono output should be confirmed from the official Rockford Fosgate datasheet.
Front/Rear Fading or Front Stage Plus Rear Sub Configurations — The T400-4 is designed for two typical 4-channel setups: a full 4-way front and rear full-range speaker system, or a front stage component system with rear subwoofers driven from the rear channels. The 24dB/octave crossover and 2/4 channel input switch support both configurations without external signal processing.
Dynamic Thermal Management for Compact Installation — Rather than a fixed protection shutdown at a temperature threshold, Dynamic Thermal Management actively manages the amplifier's output in response to temperature — reducing output as needed to prevent overheating in confined spaces. This allows the T400-4 to be installed under front seats, in centre consoles, or in other space-constrained locations where heat dissipation is limited.
MOSFET Power Supply and Output Stage — MOSFET-based design in both the power supply and output stage provides clean, efficient power delivery and responsive switching — the same proven technology used across the Rockford Fosgate Power series.
24dB/Octave Crossover — Steep crossover slope for precise frequency band separation — enabling high-pass filtering on front stage speakers and low-pass filtering on rear subwoofers, or full-range pass-through for a standard 4-way system.
2/4 Channel Input Switch — In 2-channel mode, a stereo input is internally distributed to all four output channels — allowing connection to head units with only a 2-channel RCA preamp output. In 4-channel mode, discrete front and rear RCA inputs allow independent level control.
4 Gauge Power and Ground Connectors — Appropriate wiring infrastructure for a 400W 4-channel amplifier, ensuring the power delivery path matches the amplifier's output capability.
Audiophile Grade Speaker Connections — High-quality output terminals for a solid, low-resistance connection to speaker voice coils across all four channels.

Frequently Asked Questions
What is the confirmed power output of the T400-4?
Rockford Fosgate confirms 100W per channel into 2Ω, for a total of 400W across four channels. Power output at 4Ω and the bridged mono output rating are not confirmed in the supplier data — pull the official T400-4 datasheet for the full power specification table.
What does Dynamic Thermal Management mean for installation flexibility?
Dynamic Thermal Management actively reduces amplifier output as temperature rises — rather than a hard shutdown — allowing the T400-4 to sustain operation in confined spaces like under front seats where heat dissipation is limited. The amplifier trades peak output for continuous operation in hot or restricted environments.
What is the difference between the T400-4 and the T400X4AD?
Both are Rockford Fosgate Power series 400W 4-channel amplifiers. The T400-4 is a conventional design with confirmed 100W×4 @ 2Ω, 4-gauge connectors, and Dynamic Thermal Management. The T400X4AD is the Class-AD ultra-compact variant with 8 AWG connectors, high-level auto turn-on, C.L.E.A.N. clip detection, and specific design for hybrid vehicles, UTVs, and motorcycles. The right choice depends on your installation environment and integration requirements.
Can the T400-4 run both front speakers and rear subwoofers simultaneously?
Yes. This is one of the T400-4's designed use cases — front channels in high-pass mode driving component speakers, rear channels in low-pass mode driving subwoofers. The built-in 24dB/octave crossover provides the frequency separation required for this configuration without external processing.
What gauge wiring does the T400-4 require?
The T400-4 uses 4-gauge power and ground connectors. A minimum of 4-gauge cable is recommended for the power and ground runs. Confirm the specific cable length and fuse requirements for your installation with Rockford Fosgate's wiring guide or your installer.

1,000W Class-AD 4-Channel Full-Range Amplifier Class-A Sound Quality, Class-D Efficiency, Constant Power, 2-Year Warranty.
Product Overview
The Rockford Fosgate Power T1000-4AD is a 1,000W 4-channel full-range amplifier built on Rockford Fosgate's Class-AD technology an amplifier topology combining the sound quality characteristics of a Class-A design with the power efficiency of Class-D. Where Class-BD was developed for brute subwoofer power, Class-AD is Rockford Fosgate's answer for high-fidelity, full-range speaker amplification designed for front stage component systems, full-range 4-way installations, and any application where audio quality across the full frequency spectrum is the priority.
Sound quality is enhanced through dynamic switching frequency control a technique that optimises the amplifier's internal switching frequency dynamically for improved linearity and reduced audible artefacts. Constant Power circuitry produces optimised output across a range of impedances. Combined with MOSFET power supply and output stages, 24dB/octave crossover, RCA pass-thru, and a confirmed 2-year warranty, the T1000-4AD is Rockford Fosgate's premium full-range 4-channel Power series amplifier.

Features & Benefits
Class-AD — Class-A Sound Quality with Class-D Efficiency — Class-A amplifiers are widely regarded for their linearity and low distortion but are thermally inefficient and physically large. Class-D amplifiers are highly efficient but have historically made compromises in audio quality. Rockford Fosgate's Class-AD combines the sonic characteristics of Class-A operation with the power efficiency of Class-D — delivering high-fidelity full-range amplification in a format suited to demanding car audio installations.
Dynamic Switching Frequency Control — A proprietary technique that dynamically adjusts the amplifier's internal switching frequency to optimise linearity and minimise switching-related artefacts — contributing to the Class-AD's high-fidelity performance across the full audio frequency range. This is the technical mechanism that distinguishes Class-AD's audio quality from standard Class-D designs.
Constant Power — Optimised Output Across Impedances — The Constant Power circuitry maintains optimised output across a range of speaker impedance loads — providing consistent performance whether 4Ω or 2Ω speakers are connected, without the significant power variation seen in standard amplifier designs at different load impedances.
1,000W 4-Channel Full-Range Configuration — 250W per channel (total rated — confirm per-channel at specific impedance from the official datasheet) across four full-range channels. Designed for high-output front and rear speaker systems where component speakers or full-range coaxials require substantial clean power to achieve their performance potential.
RCA Pass-Thru Outputs — Signal pass-through allows the headunit RCA signal to be looped to a downstream amplifier — enabling the T1000-4AD to drive four speaker channels while simultaneously feeding a dedicated subwoofer amplifier for a complete multi-amplifier system.
24dB/Octave Crossover — Steep crossover slope for precise frequency band management — enabling high-pass filtering on front and rear speakers and the option to configure rear channels for subwoofer use in mixed speaker/subwoofer builds.
2/4 Channel Input Switch — Accepts either a 2-channel stereo input (internally distributed to all four outputs) or discrete 4-channel front and rear RCA inputs — accommodating both 2-channel and 4-channel headunit preamp configurations.
MOSFET Power Supply and Output Stage — MOSFET implementation across both supply and output stages supports the high-current, low-noise delivery required for Class-AD's high-fidelity operation.
4 Gauge Power and Ground Connectors — Appropriate power delivery infrastructure for a 1,000W 4-channel amplifier.
Audiophile Grade Speaker Connections — High-quality output terminals across all four channels for low-resistance, high-integrity speaker connections.
2-Year Warranty — Confirmed manufacturer warranty — two years of coverage on Rockford Fosgate's flagship full-range 4-channel Power series amplifier.

Frequently Asked Questions
What does Class-AD mean and why does it matter for full-range speakers?
Class-AD combines the sound quality characteristics of Class-A amplification with the power efficiency of Class-D. Class-A designs are highly linear and produce very low distortion but are thermally inefficient. Class-D is efficient but involves switching-based operation that can introduce artefacts. Rockford Fosgate's Class-AD and its dynamic switching frequency control aim to deliver high-fidelity full-range performance with efficient power delivery — a meaningful advantage for component speaker systems that operate across the full 20Hz–20kHz range.
What is dynamic switching frequency control?
Dynamic switching frequency control is a technique where the amplifier dynamically adjusts its internal switching frequency based on the signal being amplified. This optimises linearity at each operating point, reducing the audible by-products of switching-mode amplification — contributing to the Class-AD's high-fidelity performance compared to standard fixed-frequency Class-D designs.
What is the confirmed per-channel power output of the T1000-4AD?
The total rated power is 1,000W across four channels. Per-channel power at 2Ω and 4Ω is not confirmed in the supplier data — pull the official Rockford Fosgate T1000-4AD datasheet for the full power specification table, including per-channel RMS at each impedance.
How does the T1000-4AD differ from the T600-4?
The T1000-4AD delivers 1,000W total (vs the T600-4's 600W), uses Rockford Fosgate's Class-AD technology with dynamic switching frequency control, and is specifically designed for high-fidelity full-range use. Both include RCA pass-thru. The T600-4 uses a conventional MOSFET design. For audiophile-oriented builds where audio quality is the priority, the T1000-4AD is the appropriate choice.
Is the T1000-4AD suitable for running subwoofers on the rear channels?
Yes. The 24dB/octave crossover allows the rear channels to be configured in low-pass mode for subwoofer use. However, the T1000-4AD's primary design intent is high-fidelity full-range speaker amplification via Class-AD technology — for dedicated subwoofer channels, a Class-BD mono amplifier (T1000-1BDCP, T1500-1BDCP, T2500-1BDCP) connected via the RCA pass-thru is the more appropriate and more powerful solution.
