Advanced Subwoofer Amplifier Interface for
for Select Chrysler / Dodge / Jeep Vehicles

Troubleshooting
1.
Low volume setting on radio is too loud - Set minimum volume using process outlined in Setup and Configuration, or using
the AmpPRO application.
2.
If for any reason the APSUB module becomes unresponsive, or will not power up with the key on, you can always reset the
interface by turning the key to the ignition position, then pressing and holding the Volume Down button on the factory SWC for
12 seconds until a tone is heard or by pressing and holding the reset button on the side of the APSUB module for 10 seconds
(until the LEDs alternate flashing red).
