Installing your SW 11 ACTIVE spare-wheel-subwoofer correctly is key to enjoying its full potential. Here's a straightforward guide to help you through the process:
-
Power Connections:
- Start by disconnecting your vehicle's power supply; remove the ground cable from the battery.
- Connect the GND (ground) terminal of the amplifier to your car's chassis. Use a short cable (no longer than 50 cm) of appropriate gauge (AWG size 6 - 10) for this connection.
- Connect the +12V terminal of the amplifier directly to your car battery using a fuse. Ensure the cable is high-quality and no more than 30 cm long. Use a suitable fuse holder.
- For optional control, connect the REM terminal of the amplifier to the remote output of your head unit using a 0.5 - 1.5 mm power cable.
-
RCA/Speaker Connection:
- If your car stereo has RCA outputs, connect the subwoofer to the pre-output connection of your head unit using an RCA cable and use the RCA LOW-LEVEL inputs. Also connect the remote input (usually blue) to the remote or antenna output of the head unit.
- If your car stereo lacks RCA outputs, connect your speaker outputs directly to the HIGH-LEVEL inputs of the subwoofer. In this setup, the amplifier will automatically power on via the remote wire.
-
Troubleshooting:
- If the amplifier fails to power up (no LED), inspect the ground connection, +12V power cable, remote cable, and fuses.
- If the protection LED glows green but there's no sound, check the cinch cable, speaker connections, and the head unit.
- A red protection LED indicates a potential issue. Check for overheating, short circuits, excessively high input voltage, or impedance problems.
- To resolve overheating, ensure the amplifier has adequate airflow. Following these steps will help you successfully integrate your SW 11 ACTIVE spare-wheel-subwoofer into your car audio setup.
