Works perfectly

I have a 2023 Ford Lightning Lariat with the 8 speaker B&O system. This adapted perfectly, plug and play only, to allow me to add a sub amp. I had some questions and these guys were fabulous to talk to and incredibly knowledgeable on these systems. Buy it, you won't regret it.

Works really well

I had played around with all sorts of solutions using the B&O subwoofer signal. I tried Accubass in my AudioControl amp, no accubass, 2 different LOCs. Nothing worked all that well. I got the piggyback harness for the B&O system that’s running into the Kicker Key LOC that they have pre configured. It works surprisingly well. Feel like I have a regular RCA signal out from a head unit, just like back in the 1990s! I can’t recommend this enough. I still need to clean things up but my test listen is a 10/10.

Must have for adding an Amp!!

Made adding a Kicker Keyloc to my F150 As simple as plugging it in! Highly recommend if adding an amp to your system!

Seamless integration

Without a doubt the easiest way to install an aftermarket subwoofer. Total plug and play, simple instruction, and pre configured for bass roll off. Highly recommend to skip the headache of tracing/ splicing into your factory system.

SGS Kicker Keyloc and Harness

Installed this in my 2025 Ranger Raptor along with a Hertz amp and 10" sub; the install was simple and the improve in sound quality was significant.

Great product, great service!

What more can I say. Super easy installation! Paired with a modest Punch 201S and 8" Fosgate Driver is a phenomenal improvement to the factory B&O System! I accidentally ordered the wrong variation of the harness. When contacted by email, they were quick to respond. Sent it back with the shipping label provided by customer service, and received the replacement in barely a week's time! I'm very pleased with the end result! I would recommend Sounds Good to anyone looking to upgrade their late model car stereo. Too much chance of making a mistake with all the electronic systems in today's automobiles! SOUNDS GREAT!!!

If you have a F150 you need this

Coming from a long line of Ford's, most recently a 2016 F150, 2018 Expedition Max with B&O and now a 2022 Lightning with B&O Unleashed, bass roll off has been a regular thing. This adapter completely changed the sound from the system even without speaker upgrades. You will hear your music differently. I have since replaced all the doors/tweeters/dash mids and put a 10" sub under the seat. I am beyond pleased with this plug and play solution to allow audio flexibility in my Lightning. Thanks guys!

Perfect!!!!!!

What a great experience I've had with this product and the support! They were super fast getting back to me and so helpful! They already tuned the box for the expedition as well. That I was blown away by! Literally plug and play. The tuning seemed rather daunting to say the least. So after my local stereo shop quoted me 1700 to add a sub, im so happy I found these guys!!! Lots of companies could use a lesson from these guys and gal's.

Plug and play

Very simple, plug and play. Sounds amazing and gets rid of the factory roll off

2025 Ranger Raptor. Amazing difference!!

Just buy it. It’s worth every cent. If you think your sub in your ford sounds good you’re missing out. Plug and play couldn’t be any easier. Removed all roll off and replaced sound I didn’t know I was missing

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.

Here is the installation video of the Fix Factory Roll Off solution:


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.
