Troubleshooting the Kicker Integrated Systems
If you experience a problem once the subwoofer or amplifier are installed use this guide to locate the trouble.
The radio is working, but the Subwoofer is not working:
•Check the battery voltage to make sure it is not discharged below 11 volts.
•Check the negative battery cable to see if it has been securely tightened back on the battery.
•Check the inline fuse located near the battery to make sure it is plugged in completely, and not blown.
•Check the inline +12 volt power connector near the firewall to make sure it is plugged in securely.
•Check the inline connectors near the subwoofer enclosure to make sure they are plugged securely.
•Check the ground wire connection to make sure it is tightly secured to the proper ground in the vehicle.
•Check the audio input signal connection to make sure it is secure and connected to the proper wiring.
•Test with different music in case there is no low frequency audio in the initial sound check.
