Product Research

Features

Amplifier Integration Interface: The PAC AmpPRO AP4-FD11 simplifies the installation of aftermarket amplifiers in select Ford & Lincoln vehicles with data-bus controlled factory sound systems. With the AmpPRO AP4-FD11, you can improve your vehicle's audio performance while keeping an original radio's fit, finish, and features.

Notes:

  • The factory radio and factory amplifier must remain connected in the vehicle and be operational in order to use the PAC AmpPRO interface.
  • If you are only using the PAC AmpPRO interface to add a subwoofer amplifier, the factory amplifier will still power the other speakers in the vehicle.

Vehicle Compatibility: The PAC AmpPRO AP4-FD11 amplifier integration interface is compatible with the following 2007-2014 Ford & Lincoln vehicles with a data-bus controlled factory sound system (24-pin, 16-pin, & 8-pin MS-CAN connectors).

Make Model Year
Ford F-150 2009-2012
Flex 2009-2012
Fusion 2010-2012
Taurus 2010-2012
Lincoln MKS 2009-2012
MKT 2010-2012
MKX 2007-2010
MKZ 2007-2012
Navigator 2007-2014
Note: This interface is only compatible in vehicles equipped with a data-bus controlled premium sound system. To verify compatibility, look for a Sony or THX badge on the door speakers, center speaker, or factory subwoofer. If none of these brands are shown, check for the presence of a center speaker or subwoofer.

6Ch Pre-Outs: The PAC AmpPRO AP4-FD11 provides a 6-channel pre-amp output for use with aftermarket amplifiers. Using the full-range, fixed level factory radio output, in conjunction with data-bus CAN messages, the AP4-FD11 delivers a variable 5V RMS pre-amp output with fading, balance, equalization, and level control capabilities.

Non-Fading Level Control Knob: Channels 5-6 (Sub) of the AP4-FD11 are non-fading outputs. The output level of channels 5-6 can be controlled using the supplied level control knob. The level control knob comes with a 6' cable which plugs into the interface module and should be mounted in an accessible location.

Data Controlled Remote Turn-On: A data controlled remote amplifier turn on wire is also provided by the PAC AmpPRO AP4-FD11. The remote turn-on is rated at 2A of current. If more current is needed an external relay must be used.

Retained Factory Audio Features: The PAC AmpPRO AP4-FD11 also retains all audio from other vehicle features such as factory Navigation Prompts, Bluetooth, Sync, and Warning Chimes.

Minimum & Chime Volume: If the minimum volume of your factory radio is too loud once the AP4-FD11 is installed, 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 (Steering Wheel Controls) in conjunction with the supplied level control knob. You can also use AmpPRO PC app. You can also adjust the chime volume level.

AmpPRO PC App: Using the AmpPRO PC App (for Windows PC only) allows you to configure user interface options such as Minimum Volume Level, Chime Volume Level, and a 3-Band EQ from your Windows computer or laptop. The app can also be used to update product firmware.

  • Minimum & Chime Volume Level: From the app you can set the minimum volume level of the factory radio, as well as the chime volume level.
  • 2-Band EQ: Enables the 2-band EQ (Bass & Treble) with frequency and Q-factory adjustment. The Bass Frequency can be set to 60, 80, 100, or 120Hz; while the Bass Q-Factor can be set to 0.5, 1.0, 1.5, or 2.0. The Treble Frequency can be set to 7.5k, 10k, 12.5k, or 15k; while the Treble Q-Factory can be set to 0.75 or 1.25.
  • Firmware: The AmpPRO app will also allow you to update the interface with new firmware as it becomes available.
Note: These AmpPRO PC App 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.

Dip Switch: Set dip switch 2 to "ON" to lower the RCA output voltage to 4V. Set the dip switch 2 "OFF" to keep the RCA output voltage at 5V. Dip switches 3-4 are used for troubleshooting Sync & Bluetooth. Dip switch 1 is not used.

Optional Toslink Add-On Module: When used in conjunction with PAC's APA-TOS1 (541APATOS1; sold separately), the AP4-FD11 can provide a variable 2-channel fiber optic digital audio output (toslink). Toslink fiber-optical cable also sold separately.

Optional Amplifier Harness: The APH-FD01 installation harness (541APHFD01, sold separately) simplifies speaker wire connections when using the PAC AmpPRO AP4-FD11 (sold separately) to add an aftermarket amplifier or amplifiers in select 2007-2017 Ford and Lincoln vehicles that feature factory amplified sound systems. The APH-FD01 keeps you from having to cut or modify your vehicle's original factory wiring, providing a direct connection at the vehicle's original factory amplifier location (you will need to make hardwire connections at the aftermarket amplifier/s).

Customer Q&A

6 questions already asked

Q
Hi, I'm hoping to add aftermarket amps to my factory system while retaining the original Ford head unit. Will you please verify whether or not this's capable of providing a full-range, flat signal at the rca outs or if it'll perform signal summing (2-channel at a minimum) ? I have a 2010 F150 Platinum w/Nav & Sony, thanks.

Q
If I purchased this, would I not need an Audio Control LC7i?
michael  May 08, 2018
1 answer
A
That's correct. The PAC AmpPRO interface would take the place of a line output converter if you're adding amp(s) to your factory system. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!
