I need a way to get a subwoofer RCA output from the factory wiring on a 2011 F150 without nav and without the Sony audio package. The vehicle is all stock. My customer thinks there is a way to hook up his aftermarket amp so the bass isn't killed when the volume is turned up. We looked at the PAC AOEM-FRD24 but I need to be sure this works with the factory radio and it won't EQ the hell out of the bass at high volume.
If there is a better solution please share. Thanks.
