INSTALLATION OPTIONS
Adding a full-range amp and subwoofer to a factory system:
This feature offers the ability to add a full-range amp and sub to a factory system, whether amplified* or non-amplified. (Refer to Page 3)
* For amplified models the amp must be bypassed/unplugged. Refer to MetraOnline.com for the vehicle specific amplifier bypass harness.
Note: The interface provides a 12-volt 1-amp output to turn on aftermarket amp(s). If installing multiple amps, an SPDT automotive relay will be required if the amp turn-on current of all amps combined exceeds 1-amp. Use Metra part number E-123 (sold separately) for best results.
INSTALLATION
- Remove the factory radio*, then unplug all connectors.
- Install the AXAMP-FD1 vehicle T-harness to the vehicle and make all necessary connections, but leave the amp turn-on wire disconnected.
- Plug the AXAMP-FD1 vehicle T-harness to the AXAMP-FD1 interface.
- Plug the AXAMP-FD1 interface harness to the AXAMP-FD1 interface.
- Connect the amp turn-on wire.
- Adjust your aftermarket amplifier to a desired listening level.
- The Bassknob is used to adjust the output of channels 5 & 6 of the AXAMP.
Adjustment is as follows:
Counterclockwise turn lowers the volume of channels 5 & 6.
Clockwise turn raises the volume of channels 5 & 6.
* For dash disassembly instructions, refer to MetraOnline.com. Enter the year, make, and model of the vehicle in the Vehicle Fit Guide and find instructions under Metra Radio Install kits.
