I have a 2024 Lariat 502a with B&O Unleashed speakers. The speakers themselves are really good, however it severely lacked in bass compared to other B&O systems I’ve had (2014 5 Series).
As I’ve looked across multiple forums, I found a post that recommended the Kicker KeyLOC from SoundsGoodStereo. I’ve never done any upgrades to car audio, so I gave them a call and they explained how the KeyLOC would work and how it would fix the factory bass roll off. Pulled the trigger on this during their Black Friday sale and recently got it installed with Skar Downward Facing under rear seat subwoofer box with 2 10 inch subwoofers.
All I can say is that it changes the experience immensely. Listening to music is enjoyable and especially if you like listening to music at louder volumes fixing the factory bass roll off is a game changer.
If you are looking to add bass to your truck, this pre-tuned Line Output Converter is the way to go. If you have any questions, give them a call. The person I spoke to on the phone gave some amazing tips as well which helped with the install (Running ground and power to the battery).
