The PAC APSUB-FD21 is a specialized "sub-only" integration harness designed for owners of premium Ford vehicles who want to add an aftermarket subwoofer and amplifier while keeping the rest of the factory Premium Audio system intact.
This harness provides a clean, non-invasive way to get a low-level audio signal directly from the factory amplifier's subwoofer output. It eliminates the need for messy line output converters (LOCs) or tapping into door speakers, ensuring your new subwoofer gets the dedicated signal it needs for maximum performance.
Direct Subwoofer Integration: Specifically designed to provide a 2-channel RCA output for adding an aftermarket subwoofer to the factory system.
Plug-and-Play Simplicity: Connects directly to the factory amplifier's subwoofer output harness. No cutting, splicing, or permanent vehicle modifications required.
Retain OEM Bass Control: Allows you to continue using the factory radio's bass settings to adjust your new subwoofer's output.
Seamless Installation: Provides a clean "break-out" of the factory subwoofer signal, making it easy to route to your new mono-block or bridgeable amplifier.
High-Quality Copper Leads: Uses premium wiring to ensure signal integrity and prevent the introduction of engine noise or ground loops.
Designed specifically for vehicles equipped with the Factory B&O (Bang & Olufsen) Amplified System.
