Advanced Subwoofer Amplier Interface
for Select Ford Vehicles
APSUB-FD21
The APSUB-FD21 provides a 2-channel non-fading pre-amp output for use with an aftermarket amplier and
subwoofer. Using the full range, xed level head unit output, in conjunction with CAN messages, the APSUB-FD21
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 lter applied. A data controlled remote amplier turn on wire is also
provided by the APSUB-FD21.
Introduction and Features
Important Notes
1. This interface is only compatible in vehicles equipped with a data bus controlled premium sound system. To verify
compatibility, look for a Sony badge on the door speakers, center speaker, or factory subwoofer, in the 2019-2020
Super Duty trucks and Mustang; look for a B&O badge.
2. The factory amplier must remain connected, and in the vehicle after the APSUB-FD21 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 remote output may remain active once the key has been removed if the vehicle needs to pass chime or SYNC audio.
5. 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%.
6. 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 Conguration section on page 2 for more details.
7. Ford Focus: You cannot use the steering wheel controls to activate the minimum volume adjustment.
8. The level control knob must be connected in order to manually adjust the minimum volume settings.
9. The factory radio's speed controlled volume and surround sound mode are not supported by the APSUB-FD21 outputs.
10. No adjustments can be made manually using the programming button, or the factory SWC when the module is connected to
a PC.

Setup and Con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 adjustments are 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.
