5. Installation and Wiring
The BQCC JSD-530 is designed for standard 1-DIN in-dash installation. The installation dimensions are approximately 178mm x 50mm. Ensure your vehicle's dashboard opening matches these dimensions.
5.1 Wiring Instructions
Proper wiring is crucial for the correct operation and longevity of the unit. Refer to the wiring diagram below and follow these guidelines:
- Yellow Wire (B+): Connect to a constant 12V power source in your vehicle. This wire provides continuous power to retain settings and memory.
- Red Wire (ACC): Connect to the vehicle's ignition switch (key cable). This wire provides 12V when the car is started and 0V when it is off.
- Black Wire (GND): Connect to a reliable ground point (negative terminal) in your vehicle.
- Speaker Wires: Connect the speaker wires according to the color codes and polarity indicated on the wiring harness and your vehicle's speaker system. Incorrect speaker wiring can damage the amplifier chip.
- Radio Antenna: Connect your car's radio antenna to the designated input on the rear of the unit.
- RCA Output: If connecting an external amplifier or subwoofer, use the RCA audio output jacks.

If the power cord is wired incorrectly (e.g., reversed polarity), the unit will automatically shut down to prevent damage to its internal components. This protects the main board and fuse from burning out, which would otherwise prevent the machine from starting.
