Compatible with Power T400x4ad

Power T400x4ad by Rockford Fosgate

The ultra-compact Power T400X4ad 400-watt amplifier with 4 channels is based on the Class-AD technology developed by Rockford Fosgate, which delivers the same power at both 4-ohm and 2-ohm impedances with constant performance. Flexible vehicle integration through low-level and high-level inputs with automatic turn-on function. Top-mounted controls allow easy access to the built-in crossover and the C.L.E.A.N. input/output clip detection circuit. The 3-stage thermal locking with dual fan forced induction keeps everything cool, while real-time thermo/protection systems safeguard the amplifier.

Frequently Asked Questions about Power T400x4ad

What power does the Power T400x4ad Amplifier provide?

The Power T400x4ad Amplifier from Rockford Fosgate delivers a constant power of 100 watts per channel at 4 ohms and 2 ohms. Additionally, it offers a dynamic power of 128 watts per channel at 4 ohms and 152 watts at 2 ohms. Bridged, it produces 200 watts at 4 ohms and can dynamically deliver up to 290 watts per channel. Its efficiency is over 75%, ensuring efficient operation. The amplifier is equipped with Rockford Fosgate's Class-AD technology, which enables this stable and consistent power output.

What input options does the T400x4ad Amplifier offer?

The Power T400x4ad Amplifier provides both low-level and high-level inputs for flexible integration into various vehicle audio systems. The differential inputs with automatic high-level activation allow for easy connection to different car radio configurations. Both front and rear inputs are accessible via a 4-pin wiring harness, ensuring versatile compatibility with different audio devices. These input options are ideal for easily and efficiently integrating the amplifier into existing systems without the need for separate signal attenuators.

How does the thermal Fuse work in the Power T400x4ad?

The Power T400x4ad Amplifier is equipped with a 3-stage thermal lock and a double forced-induction fan cooling system. These features ensure that the amplifier maintains its functionality in the event of unwanted heat development. The real-time thermo/protection system continuously monitors the operating temperature to prevent overheating and resulting damage. This robust cooling system made of extruded aluminum helps ensure optimal performance of the amplifier in hot environments and under high load.

What Crossover settings does the T400x4ad offer?

The Power T400x4ad features integrated Crossover controls that provide both a high-pass and a low-pass filter with 50 Hz to 250 Hz at a slope of 12 dB/octave Butterworth. These adjustable crossovers allow for precise tuning of the audio output to enhance sound quality within the vehicle. The treble control offers a range of 0 to +14 dB at 12.5 kHz, while the bass control allows for 0 to +18 dB at 45 Hz to optimize sound quality according to individual preferences.

Is the Power T400x4ad compatible with my car?

Whether the Power T400x4ad Amplifier fits in your vehicle depends on the available dimensions. The amplifier measures 4.1 cm in height, 10.8 cm in width, and 21.1 cm in depth. Additionally, it requires adequate airflow to support cooling from the built-in fans. When installing, you should ensure a stable mounting and that all electrical requirements, such as an operating voltage of 9 to 16 VDC, can be met.

Where are the controls located on the T400x4ad?

The controls of the Power T400x4ad are cleverly positioned on top to ensure easy access. This space-saving solution allows for simple fine-tuning of the built-in Crossover and the C.L.E.A.N. input/output clip detection circuit. This arrangement is particularly useful when the amplifier is installed in tight spaces, as users have direct access to all important adjustment options without cumbersome disassembly. This way, you can comfortably make adjustments as needed, even after installation.

What are the power connection requirements for the T400x4ad?

The Power T400x4ad Amplifier requires specific electrical installations for proper operation. The power connection needs a diameter of 8mm² to ensure sufficient current flow, which allows for stable performance. An average current draw is 28 A during music playback at 13.8 V, while the maximum current draw reaches 55 A under sine wave conditions. A recommended Fuse of 60 A is used to ensure circuit safety in case of sudden power spikes.

What signal levels does the T400x4ad support?

The Power T400x4ad Amplifier supports signal levels ranging from 150 mV to 12 V. This responsiveness allows for adaptation to various signal sources and ensures that the amplifier operates optimally depending on the input signal. The flexibility in input sensitivity means you can easily integrate this amplifier into audio applications with different signal level stages, whether in standard OEM or high-end aftermarket sound systems, as the amplifier unleashes its full potential regardless of the signal source.

How does the C.L.E.A.N. technology help with the T400x4ad?

The C.L.E.A.N. technology in the Power T400x4ad Amplifier allows for precise detection and monitoring of audio input and output clipping. The technology, derived from Rockford Fosgate's patented systems, reduces distortion through visual LED indications that signal when the level needs to be adjusted. This is essential for Hi-Fi enthusiasts to maximize sound quality and ensure an undistorted listening experience, even at high volumes, which is particularly beneficial when used in a vehicle.

What type of cooling mechanism does the T400x4ad have?

The Power T400x4ad features a dual fan system for forced ventilation that regulates operating temperature under heavy load. This powerful cooling system takes advantage of the aluminum heat sink design to efficiently distribute the heat generated. The combination of these elements ensures that the amplifier does not overheat even during intense use and is automatically protected by the real-time temperature measurement system. This provides the amplifier with consistently high-quality sound performance, regardless of external conditions in the car.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
