1. Remove factory radio.
2. Disconnect the 24-pin, 16-pin and 8-pin harnesses from the radio.
3. Connect the AmpPRO harnesses to the vehicle harnesses.
4. Connect the AmpPRO harnesses to the factory radio.
5. Set any feature DIP switches that apply to your install.
a. DIP switch 1 is used for two channel mode. In this mode, both the TOSLINK and front RCA outputs (1 and 2) become
non-fading outputs.
b. Set DIP switch 2 on (down) to lower the RCA output voltage to 4v. Leave DIP switch 2 off (up) to keep the RCA output
voltage at 5v. See troubleshooting section on page 5 for more details.
c. DIP switches 3 and 4 are used for additional troubleshooting. See the troubleshooting section on page 5 for more details.
6. If you are using the APA-TOS1 (sold separately) refer to the instructions included with that product for its installation.
7. Connect the AmpPRO harness to the module.
8. Connect the level control knob to the module and install in an accessible location.
9. Connect the signal cables and remote input from the aftermarket amplifier.
10. Turn vehicle off, remove the key, lock the car using the factory keyfob, and let the vehicle sit for 10 minutes. This will
ensure that the vehicle data-bus goes to sleep and the AmpPRO will function as intended.
Setup and Configuration
1. Turn the ignition on. LED 1 on the interface will turn on and the +12v remote output will turn on.
2. Set the amp gain(s) to the desired level. We recommend using an oscilloscope and test tones to set the amp gain(s).
Please refer to the MECP Advanced study guide (p. 360) if you are unfamiliar with this process.
3. Check volume, balance, fade and EQ settings.
4. If you would like to adjust the chime volume or minimum volume, do so using one of the methods outlined below. If you are
happy with the default levels, no adjustments are necessary.
Manually Setting the Chime Volume
You can manually set the level of the factory chime using either the programming button on the side of the interface, or the
factory Seek/Track buttons. If you would like to set the chime volume using the PC app please proceed to the PC App section.
PLEASE NOTE: Level control knob must be connected to module for either of the following methods.
