1000, 360, 400 specifications

Rockford Fosgate is a renowned name in the audio industry, especially recognized for their high-performance car audio systems. Among their range of products, the Rockford Fosgate Punch series, including models like the R1000-1D, R360-4, and R400-4, stands out due to their outstanding features and cutting-edge technology.

The R1000-1D is a monoblock amplifier that delivers a staggering 1000 watts of RMS power at 1 ohm. This powerhouse is particularly suited for subwoofers, maximizing bass output with minimal distortion. Its Class D topology enhances efficiency, ensuring that users get more power with less heat generation, which is a common challenge in high-performance audio systems. Integrated into the design are adjustable low-pass filters and bass boost controls, allowing users to tailor the sound to their liking. Additionally, it features an LED indicator that provides real-time feedback on the amplifier's status, making monitoring easy for users.

Next up, the R360-4 is a versatile four-channel amplifier that can deliver 360 watts of RMS power. This model is ideal for powering multiple speakers or a combination of speakers and subwoofers. With its high and low-level inputs, it is compatible with a variety of audio sources, making it a flexible choice for car audio enthusiasts. Notably, the built-in crossover system provides precise sound processing, ensuring that every component of the audio spectrum is handled efficiently. This amplifier also utilizes Rockford Fosgate's proprietary technology to reduce noise and interference, creating a cleaner sound experience.

Lastly, the R400-4 brings another level of performance to the table with its 400 watts of RMS power output, designed for full-range applications. This amplifier features a compact design, allowing for easy installation in tight spaces. Like the R360-4, it also features high and low-level inputs along with built-in variable crossovers. The thermal and speaker short protection circuitry ensures safety and longevity, providing peace of mind for users.

All three models exemplify Rockford Fosgate's commitment to excellence, making them a popular choice among car audio enthusiasts who prioritize power, versatility, and sound clarity. Whether you are seeking a powerful bass experience or a balanced audio system, the R1000-1D, R360-4, and R400-4 are designed to elevate any car audio setup to new heights.
