So, I bought a 2016 a while back, and I've been learning things about it. Added a subwoofer and enabled the connector in the back. Then I decided to check the grille in the dash, and there's a speaker in there! It was not enabled, so I popped up forscan and enabled it. Did Ford put speakers in but just not enable them?

 

Thats interesting, I have the grille there too but am fairly certain it's disabled/doesnt pump out sound.

 

Previous owner probably disabled it. It throws off the sounds stage according to folks around here. My poor man model didn't have it so I have no idear.

 

What did you change to enable it?

 

Leave it off, it sounds horrible when working. It's just a cheap speaker I think put there to playback program sounds.

 

In FORSCAN, ACM config, 7 speaker crew cab. I decided after trying it, it definitely didn't add anything nice. Thankfully I had backed up my OEM configuration. Oddly, it defaults to "not configured." This probably removes any audio filters. Then I just enabled the subwoofer output and left everything else alone.

 

Interesting, that had no effect in my truck. I don't think "not configured" is connected to the audio filtering. It's what the default is for my truck as well. I used a JL Audio FiX when setting up my amps since I was getting a lot of noise when running the high level speaker outs into passive RCA converters. The FiX plays a test tone and automatically calibrates the OEM audio output to be flat. You can then set your own per-channel EQ and crossover frequencies. Ford appears to have added bass to the front speakers. I think people think they cut bass to the rear, but that doesn't seem to be the case. The before and after for the rear speakers are relatively flat.
