Complete Made Plug & Play T-Harness for Base Model Factory Systems with Straight-Wire 4-Channel RCA Ends for Balanced Differential Inputs (Contact us for details if your gear offers this).
Keep in mind, some Base model vehicles have a factory EQ curve that needs to be set to 0 using a For Scan tool, and also it is recommended to set the outputs to Low-Level 4v.
Using an LC7i, LC2i, or any other Line Output Converter will not help and is not needed on these trucks. You either use a For Scan to do the steps above or you have to use a device like the Kicker KeyLoc of the JL Audio Fix86.
Fits:
Compatible with 2015-2020 Ford F-150 Without Amplifier/Subwoofer
Compatible with 2017-2019 Ford SuperDuty Without Amplifier/Subwoofer
