PAC LPHFD31 LocPro Advanced T-Harness select 2018-up Ford vehicle without a factory amp

Product details

Adding an aftermarket amplifier will beef up the sound of any audio system, even when you can't replace the factory radio. PAC's LPHFD31 LocPro Advanced T-harness makes amplifier installation a lot easier by giving you access to the speaker-level output signals from your Ford factory radio. You can use this T-harness to connect to an amplifier or signal processor with speaker-level inputs, or to a line output converter with an amp.

Provides signal for your system

PAC designed this vehicle-specific T-harness to work with their LPA LocPro Advanced line output converters, but it'll also work with almost any sound processor or line output converter, as well as most amplifiers with high-level inputs. The harness also supplies the connection wires for low-power constant 12 volts (fused for your protection), accessory power, ground, and remote turn-on leads for a system device like an active signal processor.

Note: The power and ground wires in this harness will only support a low-current accessory, like an active line output converter or digital signal processor, and should not be used to power an amplifier.

How it works

First, you unplug the radio, and install the T-harness. One T-harness plug goes into the radio, the other snaps into the plug you just took out. You're then left with the radio still completely connected to your vehicle, with the addition of a pigtail of wires to use for adding an amp.

Adding a subwoofer amplifier

The T-harness pigtail includes four speaker-level channels — eight wires — that you can use to provide the input signal for a subwoofer amp or powered sub.. The amplifier will have to get its power and ground connections separately. The factory radio will still run all the speakers.
