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!
