Ford B&O Subwoofer Harness – Add an Amp & Sub, Fix or Keep the Bass Roll-Off (2018-2026 F-150, Super Duty, Ranger)

The keyloc is a must for 2024 F250 with 8 speaker B&O system. Completely plug and play, works perfectly with a Kicker hideaway HS12 behind the rear seat. This setup provided the exact amount of low end fill I was looking for in the rear of the cab.

Awesome! Completely fixed the lack of bass in the factory B&O Unleashed system. Was able to seamlessly add my subwoofer system with this product.

This setup made adding an amplifier to my 2026 F‑250 incredibly easy. The factory‑matched harness adapters were a huge win — true plug‑and‑play with zero cutting or splicing of factory wires. Tapping the door speakers and running that signal through the KeyLOC gives me a clean, strong output with absolutely no bass roll‑off, fixing the biggest flaw in the stock B&O system. The product arrived well‑packaged, and the online install videos made everything straightforward. Highly recommended.

Straight forward plug and play setup perfectly pre-tuned for sub amp. Doesn’t get any easier than that.

Had to recalibrate the keyloc once installed, and re tune the keyloc. Worked as should after this was done.

Originally I thought that I’d get away with only a powered Kicker subwoofer to satisfy my needs. After a couple months - yeah better but not great.
Added this ‘roll-off solution’ and have been impressed with the improved sound quality, noting that the music source mat’l makes a huge difference too. Going past 20 on volume, still sounds great.
Install was straight forward.

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

Installation was a breeze with your harness. I merged it with the JL high/low harness and she fires right up. Just have to finish tucking wires under the bench area. Thanks for the great product and support!

Don’t waste your time and money trying to nickel and dime your project, these guys made it as easy as possible to add the bass that was lacking with the stock set up. I installed quite a few systems back in my “school days” but it’s just not the same anymore especially when keeping your stock set up on these new vehicles.. do yourself a favor and order this kit from these boys and be in and out in 2 hours (total install) everything was plug and play and sounds great. Safe your self the time and trouble.

If you’re looking for the EASIEST way to integrate an aftermarket amp & sub into your factory B&O system on a Ranger Raptor without hacking into any of the factory wiring, while keeping the rest of the system factory intact, than seriously look NO further! This kit is all you’ll need to accomplish that exact task. Plus, with the pre-programmed Kicker Keyloc it’s already dialed in to address the bass roll off issue that’s synonymous with the B&O system. Especially if you’re going the route of adding an amp & sub that issue will magnify itself. This pre-set Keyloc will take care of that and it’s already set up for the Ranger interior. If that's not a piece of cake install factor then I don’t know what is.
The added harness to tap into & between the factory amp wiring is every bit as well made as a factory Ford piece and the connectors look & feel like they came out of a Ford parts bin. Plus, it’s wrapped for abrasion protection.
Couldn’t ask for a better solution if you’re looking to jettison that weak 5 1/4” inch factory sub.

Installed the kicker keyloc on my ‘25 Ranger Raptor B&O system. Thank you for a great and easy to install, tech support was very helpful. Thanks again system sounds clean and powerful, JL 500w amp , Rockford T1S2-10 sub loaded into a Skar under seat box.

Harness works perfectly. For those trying to see it connects to the black connector on the other side of the green connectors, so you have to take apart the stock sub (see picture).

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.

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.

The harness and KEYLOC worked exactly as described. I had a few questions pre and post install and the customer service is top notch! I will definitely be back for more products!

Installed in a 2019 raptor with B&O stereo. Wired it so that I can turn off the added subwoofers with a axillary switch but it can still run the factory subwoofer. The kicker KeyLoc works right out of the box and no adjustment needed. They do a great job adjusting at Soundsgood Stereo. Have installed the two 12" subs so that it is a quick disconnect and can install the self powered slim 12" sub without any trouble.

I love it when stuff works the way it's supposed to, like this harness adapter. Installed the behind the seat subwoofer enclosure with dual 6.5" subs and this adapter let.me go right from the factory box to the Kicker Key lock without having to do any wiring of any sort. Made installation a breeze and I have mega-bass now

I utilized this harness with a JL Audio Stealthbox
on my 2020 F-250. Installation was simple and able to retain all other factory B&O components.
