Connecting your SW 11 ACTIVE spare-wheel-subwoofer for optimal sound involves a few key steps. First, ensure safety by disconnecting your vehicle's power supply: remove the ground cable from your car battery.
Here's how to proceed:
-
Power Connections:
- Ground (GND): Connect the amplifier's ground connection to your car chassis. Keep the ground cable short (under 50 cm) and use an appropriate cable cross-section (AWG size 6-10).
- +12V Power: Connect the amplifier's +12V contact to the vehicle battery via a fuse. Use a high-quality fuse holder and keep the cable length under 30 cm.
- Remote (Optional): Connect the REM terminal to the head unit's remote output, using a 0.5-1.5 mm power cable.
-
RCA/Speaker Connection:
- RCA Output (if your head unit has them): Use RCA cables to connect the subwoofer's RCA LOW-LEVEL inputs to your head unit's pre-output connections. Connect the remote input (blue wire) to the head unit's remote or antenna output.
- Speaker Output (if your head unit lacks RCA outputs): Connect your head unit's speaker outputs directly to the subwoofer's HIGH-LEVEL inputs. The amplifier should then power on automatically.
-
Troubleshooting:
- No Power/LED Off: Check the ground connection, +12V power cable, remote cable, and fuses.
- Protection LED (Green) / No Sound: Check the RCA cable, speaker connections, and head unit.
- Protection LED (Red): Check for overheating, short circuits, high input voltage, and impedance issues. Ensure the amplifier has proper airflow if overheating.
Following these steps will help you properly install your SW 11 ACTIVE spare-wheel-subwoofer and enjoy enhanced audio in your vehicle.
