To connect the Lanzar AQTB8 subwoofer to your car's audio system, you have two options: low-level input wiring or high-level input wiring.
1. Low-Level Input Wiring:
- Use a high-quality RCA cable to connect the low-level (RCA) input of the subwoofer to the RCA outputs of your head unit or another signal source.
- If your installation requires a long cable, use a 15-20 foot RCA cable for trunk or hatchback installations, or a 6-12 foot RCA cable for pickup trucks and under-seat installations.
2. High-Level Input Wiring:
- If your head unit does not have RCA outputs, you can use the high-level (speaker level) inputs of the subwoofer.
- Connect the speaker outputs from your head unit to the high-level input connector of the subwoofer, ensuring proper polarity to avoid audio phase problems.
Note: Do not connect both the high-level and low-level inputs from your receiver to the subwoofer at the same time.
For more detailed instructions and diagrams, please refer to the "Power Connections" and "Low Level Input Wiring" sections in the Lanzar AQTB8 Low Profile Slim Amplified Waterproof user guide.
