Installation Notes
1. 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.
