Advanced Subwoofer Ampliîš¿er Interface for
for Select Chrysler / Dodge / Jeep Vehicles
APSUB-CH21
The APSUB-CH21 provides a 2-channel non-fading pre-amp output for use with an aftermarket ampliîš¿er and
subwoofer. Using the full range, îš¿xed level head unit output, in conjunction with CAN messages, the APSUB-CH21
delivers a low pass variable 5v RMS pre-amp output with bass equalization and level control capabilities. The signal
has a 350Hz / 24dB Linkwitz-Riley low pass îš¿lter applied. A data controlled remote ampliîš¿er turn on wire is also
provided by the APSUB-CH21.
Introduction and Features
Important Notes
1. This interface is only compatible in vehicles equipped with a data-bus controlled ampliîš¿ed sound system. To verify
compatibility, look for an Alpine, Beats, Inîš¿nity, or Harmon Kardon badge on the door speakers, center speaker, or factory
subwoofer grill. If none of these brands are shown; check for the presence of a center speaker or subwoofer.
2. The factory ampliîš¿er must remain connected, and in the vehicle after the APSUB-CH21 has been installed.
3. The remote output is rated at 2A of current. If more current is needed; an external relay must be used.
4. The subwoofer outputs are non-fading. The output level of the subwoofer channel can be controlled using the supplied
level control knob. If the level control knob is not connected the output level will default to 100%.
5. The minimum volume level is set to a default. If you are happy with this level in your particular application then additional
adjustment is not required. Please refer to the Setup and Conîš¿guration section on page 2 for more details.
6. The level control knob must be connected in order to manually adjust the minimum volume setting.
7. No adjustments can be made manually using the programming button or the factory SWC when the module is connected
to a PC.

Setup and Conîš¿guration
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 minimum volume, do so using one of the methods outlined below. If you are happy with the
default level, no adjustment is necessary.
Manually Setting the Minimum Volume
If the minimum volume of the radio (factory radio volume level 1) is too loud, you can manually set the level of the minimum
volume using either the programming button on the side of the interface or the factory SWC. If you would like to set the
minimum volume using the AmpPRO app, please proceed to the AmpPRO App section.
PLEASE NOTE: Level control knob must be connected to module for either of the following methods.
Installation
1. Remove factory radio.
2. Disconnect the gray 22-pin factory harness connector from radio.
3. Connect APSUB harness to vehicle harness.
4. Connect APSUB harness to factory radio.
5. Set any feature DIP switches that apply to your install.
- Set DIP switch 2 on (down) to lower the RCA output voltage to 4v. Leave DIP switch 2 o󰀨 (up) to keep the
RCA output voltage at 5v.
- DIP switches 1, 3, and 4 are not used.
6. Connect the APSUB harness to the module.
7. Connect the level control knob to the module and install in an accessible location.
8. After the aftermarket ampliîš¿er power/ground connections are made, connect the signal cables and remote input from the
aftermarket ampliîš¿er to the APSUB.
9. Reconnect any additional harnesses removed from the radio and reinstall the radio.

PLEASE NOTE: These settings can be adjusted with the module installed in the vehicle or on the bench. However, it is
recommended to make the adjustments with the module installed, and the factory radio on so that the changes can be
heard.
Minimum Volume Level - This allows you to set the minimum volume level of the factory radio (factory radio volume level 1).
EQ Enabled - This allows you to enable / disable the bass band factory EQ.
Bass Freq / Q Factor - This allows you to set the center frequency that will be adjusted when setting the bass band on the
factory EQ, as well as the Q Factor for each frequency. The Q Factor determines how many of the adjacent frequencies will
be a󰀨ected when adjusting the selected frequency. The lower the Q Factor, the more frequencies will be a󰀨ected. Note: This
setting only a󰀨ects the output of the APSUB and does not change the way that the factory EQ adjusts the factory speakers.
Setup and Conîš¿guration (cont)
Setting the minimum volume using the programming button
1. Start with the level control knob turned all the way down (counter-clockwise).
2. Set the amp gains to the desired level.
3. Set the volume on the factory radio to 1.
4. Press the programming button on the side of the interface once.
5. LED 1 will turn amber.
6. Turn the level control knob clockwise until the desired minimum volume level is reached.

PLEASE NOTE: The radio will respond to the SWC commands during this process, this is normal and has no e󰀨ect on the
APSUB operation.
5. LED 1 will turn amber.
6. Turn the level control knob clockwise until the desired minimum volume level is reached.
7. You can now either press the programming button once or wait ten seconds to exit the settings.
