FOSI AUDIO CA 30 CAR AMP 4 ch.

FOSI AUDIO CA 30 CAR AMP 4 ch. The Fosi Audio CA30 is a power amplifier for car audio systems. Designed around the Infineon IR4322 amplifier chip, it delivers 4×100W under 4Ω, or 2×320W under 4Ω in bridged mode, using a high-efficiency architecture that delivers stable current while limiting internal heat build-up. This design results in a SINAD ≥ 80dB and THD+N ≤ 0.008%, ensuring low distortion reproduction, while a signal-to-noise ratio ≥ 100dB and background noise limited to ≤ 200μV preserve the clarity of micro-information, regardless of the listening level.

Designed for car audio systems requiring both dynamic reserve and configuration flexibility, it can be used in four independent channels to power a front/rear set, or in two bridged channels to drive more demanding loads. Beyond pure performance, this approach is accompanied by a set of active protections to guard against overheating, short circuits, overvoltage, undervoltage and polarity reversal, continuously monitoring electrical parameters to secure the installation and speakers.

The high-level input supports automatic power on/off. When using a high-level input with DC, the REM connection is not required. 2. For dual protection, please install a 60A external fuse on the power cable within 50 cm of the vehicle battery. 3. To minimize interference, route power cables and signal cables on opposite sides of the vehicle (e.g., signal cables on the left, power cables on the right). 4. Please use properly rated cables. Power and ground cables must be AWG #4, and the REM wire should be AWG #16 to #18. 5. Do not connect high-level input and RCA low-level input simultaneously. 6. Multiple speakers can be connected in parallel to a single channel. In stereo mode, total impedance per channel must not be lower than 2 Ω; in bridged mode, not lower than 4 Ω. 7. Observe correct polarity for all power and audio connections to prevent short circuits or damage to the amplifier and vehicle. 8. The CA30 features cooling fins on the top panel. For optimal cooling, please install the amplifier with the fins facing upward, maintain 5–10 cm of clearance, and do not cover the fins during operation.
