You have to take it out of the dash

Can a head phone be plug into the unit and if so - can you hear sound over the head phone. Also first look if nothing is stuck in the head phone jack (where it is plugged in as kids tend to stuff small objects into it). If sound can be heard over the head phones the unit is ok. The problem then lies with in the speaker output circuitry. The speaker output wiring has most of the time a inbuilt fuse that protects the circuitry when the speaker wires are shorted out when power (volume) is on. The unit has to be opened to replace it by a knowledgeable person.

there is an amp usually built into the factory head unit or mounted in the dash behind the head unit. I would try running a new wire straight from the back of the stereo to the speaker and see if it works. if it does then you have a broken wire and need to run new ones

The head unit should have a RCA Sub Out. The RCA wire goes to the Sub Amplifier, along with power, ground, and a blue remote wire from the Head Unit. Next, the Sub Amp is wired to the Subwoofer with speaker wire. Without an amplifier your sub won't make any noticeable sound.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

check you Fade and Balance,sometime the ground is used for two speakers sometimes a ground is used more then once will cause your problem ........Good luck......

U have a Factory audio auxiliary amp in the truck, the radio is just a head unit with a preamp feeding a main amp, that is behind the right rear 1/4 panel trim panel in the cargo area, if your new sound unit has preamp outputs use them, other wise u must wire around the Ford factory amplifier.

Here are the factory wire colors, please rate this solution to your problem, a note any stereo store that sells auto decks has adapter wiring harnesses to do a direct plug in of your DIN standard radio you are trying to install, no cutting of the factory harness, they are cheap
