Great product - KeyLoc and harness adaptor for Unleashed Stereo

Bought this KeyLoc and harness so I could put an aftermarket sub in my truck without the factory roll off to the subwoofer. Everything was great and Don provided excellent customer service/support.
Thanks,
Travis

Easiest install

What an easy upgrade the kicker key made. The guys at sound good have this figured out for such a simple install. Took all of about 3 min to open the box, plug it in, mount the key, and play away. No bass roll off is such a game changer as well.

The Pre-Programmed Kicker KeyLOC is the best

The pre-programmed Kicker KeyLOC and custom wire harness from Sounds Good made the installation of a powered sub in my 2025 Ranger Raptor very easy. Not having to go through the KeyLOC set up process or cutting factory wires makes this combo worth every penny. I would highly recommend this to anyone adding an aftermarket powered sub to a Ranger or Ranger Raptor.

True plug and play!

Really simplified install! Nice to just get all set up and ready to go without buying seperate harnesses etc.

Easy install with Harness

Installation was a breeze with Soundsgoodstereo harness. Always quality products, have been using these products for last 5 years.

Green connector would be better

Sounds Good is a great company and they have made great solutions available for hard to solve problems. The subwoofer connector to RCA adaptor functions perfectly but would be better if it had the green connector outside of the factory sub instead of the black one inside. This would avoid having to disassemble the factory sub to hook up and make it easier to occasionally removing the sub when the space is needed.

Exactly what I needed

Super easy to install, provided the correct signal to my aftermarket amp and sub and now the system sounds amazing.

Simple, Functional and High Quality

Really happy with my purchase. This made adding an amp to my 2024 F150 a breeze. The only room for improvement I see would be having a slightly longer pigtail on the harness. On the 2024+ trucks they moved the amp to the left side and a little longer cable would have given me more flexibility in mounting, but I was able to tuck it away nicely under the passenger read seat.

Keyloc pre-configured ready to use

The pre-configured Keyloc and T-harness combo made adding a better sub to the B&O Unleashed system in my 2022 F150. I think it was worth the extra cost to have the Keyloc arrive fully programed and ready to go. The T-harness really made installation easy. The only thing you have to figure out is where you want to mount the Keyloc. I attached mine to the B&O amp plate with a couple nutserts. Wire was perfect length to mount here, too.

Great Product, Awesome service!

I have not dabbled in upgrading a car audio system in over 15 years. I upgraded my 2023 F150 with a new amp & sub. This harness made connecting to the factory B&O system a breeze. I reached out to Don a few times via email to help with a couple questions I had. He instantly responded to me each time within minutes and eliminated any confusion I had. What a great product with even better support!

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. No fun and not the experience our customers expect.

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 (Yellow/Black), 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.
