Ford B&O Unleashed Rear-Speaker Access Harness - 2021-2023 F-150

Why this harness exists

On 2021-2023 Ford F-150 B&O Unleashed trucks, Ford wired the rear door speakers off the factory radio (ACM) — not the B&O amp behind the rear seat. When you upgrade the Unleashed system and want to power those rear speakers with your own amp, you have to get your amplified output onto the factory wires that run from the dash back to the rear door positions.

This harness is the clean way to do it. It does not carry any signal on its own — it simply provides the speaker-wire leads that go to the factory rear speaker locations. You plug it in at the ACM under the center channel, then connect your amp's output to the leads. Your amp's amplified signal rides the existing factory wiring back to the rear door speakers.

The alternative — pulling door cards and splicing into the speaker wires inside the doors — is invasive, inconsistent, and risks door seals and trim clips. This harness gets you to the same wiring at the dash in about 10 minutes, fully reversible, factory-looking.

When you need this harness

• 2021-2023 F-150 with the B&O Unleashed (18-speaker) system
• You're upgrading with an aftermarket amp and want to power the factory rear door positions
• You want to do it without pulling door cards to splice into the factory rear-speaker wires

What you're actually getting

• A plug-in T at the factory ACM connector
• Break-out leads that connect to the factory wires running to the rear door speakers and tweeters
• TechFlex-sleeved, OFC copper throughout
• You wire your amp's speaker-level output to these leads — your amplified signal then travels the factory wiring path to the rear positions

What this is NOT: this is not a signal tap for a DSP. It doesn't pull a clean input signal from the ACM. If you need an input signal for a DSP or processor, that's a different product — call us at 615.610.1413 and we'll point you in the right direction.

Not sure if your truck is Unleashed? Only F-150 with the 18-speaker system (badge on the dash, confirmed on your build sheet) is Unleashed. Text a photo of your trim to 615.610.1413 if you want us to confirm.
