Does this amp harness come with instructions?

The gray plugs are plug-and-play, cannot mess that up. The three wires need to be connected from our custom harness:
Yellow = Power (Input)
Black = Ground (Input)
Blue = Remote Turn On (Output)

The KeyLOC itself is pre-programmed, in our truck before it ships, so no need to be an audio expert with fancy tools, we handle this for you.

I'm sure everyone knows of this problem and everyone is fighting to fix it. We have been using this method for a long time, but just now had time to add it to our website so you can purchase it easily. It's the same setup that we use on our packages and is the proper way to fix the bass roll-off.

Here is a copy/paste that I just wrote for our website that explains more. Any questions, please let me know

Option- Fix Factory Bass Roll-Off:
We have tested thoroughly just about every integration option on these trucks and while some can try to prevent the bass roll-off, they are simply a band-aid that does not work very well. Most are just a bass boost on the bottom end, but this boost exists when the roll-off is not happening, so you will constantly fight the remote subwoofer level/bass knob to "tame" the new subwoofer system.

Our approach is very different than most, but it is backed by testing along with a few key patents that make this happen. Instead of utilizing the factory subwoofer connection, we utilize a pair of interior speakers. Now these speakers do not have much subwoofer bass going to them, but it's just enough for the Kicker KeyLOC integration module to restore it properly. So why did we choose the Kicker KeyLOC? Well, it's the only integration module that can fix the All-Pass Filters on the interior speakers. Since we need both the left speaker and the right speaker to create the signal, we need to combine them to create one. As you might know, the left speaker has a totally different tune than the right. So a simple "Line Output Converter" is not the correct device for this vehicle, the KeyLOC is the only one in our industry that can do this properly...remember the patents I mentioned??

This option includes a custom-made harness by our team and is pre-programmed at our facility to match your truck's factory stereo system. Just connect the power/ground, remote turn-on, and the included RCAs from the custom harness to your amplifier. Then you now have the professional way to fix the bass roll-off and have the signal you need for a great subwoofer system.


Option- Keep Factory Bass Roll-Off:
As you might have already experienced, the factory B&O systems will roll back the bass over volume 14 and it will come in and out depending on the song. This roll-off exists to protect the factory subwoofer from damage, but for most users, it creates an unpleasant listening experience. This harness uses the factory subwoofer connection, so the roll-off will still exist at volumes over the 14 mark, but if you are a lower volume level listener or just want more bass in a cost-effective manner, this harness is for you. This harness connects at the subwoofer, not the green plug on the enclosure. Simply remove the subwoofer from the enclosure and our harness plugs right in. No need to splice wires to upgrade the subwoofer system in your vehicle.

For the High-Level and low-level options. You will need to see if your amplifier accepts speaker-level/high-level inputs and how. For example, here are several popular amplifiers and if they accept High-Level inputs:

Arc Audio High-Level = RCA
Mosconi High Level = RCA
Kicker = RCA
New Alpine High Level = RCA
Older Alpine High Level = Speaker Wire
JL Audio High-Level = RCA
Audiocontrol High-Level = Speaker Wire
New Rockford High-Level = RCA
Old Rockford High-Level = Speaker Wire
Skar Audio RP Series High-Level = Does not have it, you cannot use soldered RCA from your ACM. You must convert this with a LOC or Kicker KeyLOC, etc.
Sundown Salt Series High-Level = Does not have it, you cannot use soldered RCA from your ACM. You must convert this with a LOC or Kicker KeyLOC, etc.
DD Audio M Series High-Level = Does not have it, you cannot use soldered RCA from your ACM. You must convert this with a LOC or Kicker KeyLOC, etc.
Rockville = High-Level = Does not have it, you cannot use soldered RCA from your ACM. You must convert this with a LOC or Kicker KeyLOC, etc.
etc....

Any questions, please let us know and we can guide you in the right direction.

This looks great, where do you mount the factory B&O amplifier with this setup? Looks like the amp mounting board you show goes where the stock amplifier goes..

Yes, every single KeyLOC, Amplifier, DSP, etc is tuned in our truck.... We set our truck to have the ability to change to 7 different factory systems + all of the factory EQs that Ford provides. During the KeyLOC tuning process, we are utilizing Oscilliscope, DD1, DMM, and RTA to validate each tune/setup before it goes on the shelf for inventory..
