Fosi Audio CA30 Redefining Sound Quality in Car Amplifiers

Engineered for audiophile-grade performance, the Fosi Audio CA30 takes the expertise of Fosi’s home audio innovations into the automotive realm. The unit features a precision-tuned Infineon IR4322 Class-D amplifier chip and high-quality op-amps, ensuring a noise floor below 200µV, total harmonic distortion plus noise (THD+N) below 0.008%, and a signal-to-noise ratio above 100 dB. This results in a clean, dynamic sound that brings out the nuances in your favorite tracks, making it a standout addition to any audio components setup.

Designed with universal compatibility in mind, the CA30 works with 99% of gasoline and electric vehicles, supporting a wide 10–16V input range. Its compact dimensions of 186 mm × 101 mm × 44 mm make it an ideal choice for installations where space is at a premium, such as under a seat or in a glovebox. Despite its small footprint, the amplifier delivers powerful output: 100W per channel at 4 ohms, 160W per channel at 2 ohms, and 320W per channel in bridged mode at 4 ohms, making it suitable for driving a variety of speakers and subwoofers.

Efficiency and reliability are at the core of the CA30’s design. The combination of an aluminum-alloy chassis and sculpted cooling grooves ensures efficient heat dissipation, allowing for stable performance even during extended listening sessions. Built-in protection and clipping indicators provide real-time feedback for overheat, short-circuit, and distortion events, contributing to safe and worry-free operation. The amplifier also supports synchronized power control with your head unit via REM input, and a delayed-mute circuit eliminates unwanted pops during power transitions. For users seeking a seamless integration, the CA30 is a perfect fit for amplifier modules and sophisticated amplifiers projects.

The Fosi Audio CA30 is not only a powerhouse for car audio, but also a versatile tool for DIY installations and upgrades. Its wide frequency response (10 Hz–40 kHz), adjustable low and high pass crossovers (50 Hz–250 Hz), and high input sensitivity (0.75–8V) make it adaptable for custom DIY amplifier kits or as an upgrade in advanced automotive sound systems. Whether you are building a new system from scratch or looking to enhance your current setup with high-performance amplification, the CA30 offers an exceptional blend of sound quality, efficiency, and dependable protection.
