Frequently Asked Questions about Power T400-4

What power does the Rockford Fosgate Power T400-4 provide at 4 Ohms?

The Rockford Fosgate Power T400-4 delivers an RMS continuous power of 60 Watts per channel at an impedance of 4 Ohms. This power ensures clear and strong playback of your music. Additionally, the Amplifier can operate at 200 Watts bridged at 4 Ohms, which allows for intense use of its full power capacity. Thanks to its dynamic power, the Amplifier even reaches 84 Watts per channel at 4 Ohms, ensuring that you can enjoy full audio quality without distortion. The Amplifier is robustly designed and intended for demanding use in audio systems. It particularly shows its strengths with large speaker configurations.

What Crossover does the T400-4 Amplifier use?

The Rockford Fosgate Power T400-4 is equipped with a 24dB/octave Butterworth Crossover that can be used for both high-pass (HP) and low-pass (LP) operation. These Crossovers enable precise sound management in the frequency ranges between 50 and 500Hz to ensure optimal sound quality. The correct setting of the Crossover is crucial to maximize the efficiency of the speaker system and avoid distortion. This high-precision Butterworth Crossover is specifically designed for audiophile demands and ensures outstanding sound fidelity. By adjusting the frequencies, you can perfectly tune the sound.

How does the operating voltage of the Power T400-4 affect performance?

The operating voltage of the Rockford Fosgate Power T400-4 Amplifier ranges between 9 and 16 VDC. This voltage is important to ensure the optimal performance of the Amplifier. A higher voltage range stabilizes the power supply and positively affects both efficiency and sound quality. With an average current draw of 30 A at 13.8 V music power and a max current draw of 60 A at sine wave, a constant and stable power supply is essential. The flexibility in the operating voltage range allows the Amplifier to be used in various automotive systems without causing a loss of power.

What sound settings does the Rockford Fosgate Power T400-4 offer?

The Power T400-4 features precise sound settings. For the front channels, you can adjust the treble with Punch EQ from 0dB to +12dB at 12kHz and the bass from 0dB to +18dB at 45Hz. The rear channels offer the same adjustment options to tailor the sound to your preferences. These settings allow for detailed fine-tuning and support adaptation to various music styles. Especially if you enjoy listening to music loudly or prefer subtle tones, these customization options provide excellent sound. This way, you can get the most out of your audio system.

What type of power supply does the Rockford Fosgate T400-4 use?

The Rockford Fosgate Power T400-4 utilizes a MOSFET power supply and MOSFET output stage. This technology enables efficient power control and ensures low heat generation with high power output. MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are known for their fast switching speed and reliability, allowing for clear and undistorted playback of audio signals. The amplified design of this technology also supports the longevity and efficiency of the Amplifier. This type of power supply is essential for the performance and sound quality of the Amplifier, especially in demanding audio systems.

What compatibility does the Power T400-4 offer with car stereo systems?

The Power T400-4 is universally applicable in most car models due to its dimensions of 5.42 x 20.68 x 34.69 cm. Its compact design allows for installation, for example, under the front seats. The four-channel configuration is perfect for stereo audio systems with front and rear speaker blending or for amplifying stage speakers and subwoofers. The sturdy audiophile speaker connections and 4-gauge power/ground connections ensure secure and high-performance installations and operational compatibility. The flexibility in installation makes it versatile for different vehicle models without special modifications.

How does the Total Harmonic Distortion (THD+Noise) affect the sound quality of the T400-4?

The Rockford Fosgate Power T400-4 has a total harmonic distortion (THD+Noise) of less than 1.0%. This low distortion is crucial for clean and clear sound reproduction. A low THD reduces unwanted sounds and background noise that may occur at higher volumes. This is especially relevant for audiophiles who expect an authentic and uncolored sound image. The exact sound character of the amplifier is maintained even during intense music pieces. This technical specification demonstrates the high quality and efficiency of the amplifier, particularly in reproducing dynamic musical passages.

What input options does the T400-4 amplifier offer?

The Rockford Fosgate Power T400-4 offers versatile input options to seamlessly integrate into various audio setups. With a front low-level input via an RCA pair and a rear low-level input also via an RCA pair, it is flexible to adapt to different sources. The input switch allows toggling between 2CH and 4CH, making it ideal for both simple and complex audio configurations. These options provide exceptional flexibility to incorporate additional audio sources or extended audio output drivers, thereby maximizing sound quality and setup potential.

How does dynamic thermal management affect the performance of the T400-4?

The dynamic thermal management of the Power T400-4 enables efficient operation at high power by optimally dissipating the generated heat. The convective cooling prevents overheating, even during intense music sessions or in tight installation spaces, such as under front seats. This technology ensures long-term performance and prevents thermal shutdown that could disrupt sound continuity. Especially in vehicle environments where ventilation is limited, this system proves to be particularly advantageous. Thus, you can utilize the maximum power of your amplifier without worrying about temperature issues.

What measure should be considered when installing the Power T400-4?

When installing the Rockford Fosgate Power T400-4, proper cable sizing should be observed, especially using 8mm² power and speaker cables. These ensure a safe and reliable power supply and signal transmission. It is important to install the amplifier in a location where it fits according to the recommended dimensions of 5.42 x 20.68 x 34.69 cm and receives adequate ventilation to support cooling. These measures will not impair the performance of the amplifier while ensuring operational safety. The choice of installation location should be strategic to achieve sound optimization.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
