6.75" Sub in Factory B&O Enclosure - Anyone Tried It?

[PMRaptor]

Has anyone tried fitting a 6.75" sub in the stock B&O enclosure on a 2024+ Ranger/Raptor?

I’m considering the Kicker CompRT 48CWRT674 (6.75", dual 4-ohm voice coil). From what I’ve been able to find, the factory sub is around 5.25" and also appears to use dual voice coils, so the Kicker looks like it might be a reasonable option electrically if it can be made to fit with a simple adapter/spacer.

I’m not looking for a big bass upgrade. I’ve already replaced the door speakers with Focals, added sound deadening, and I’m replacing the centre speaker with an Infinity. I’d just like to improve the factory sub a little while keeping the stock B&O amp and avoiding a separate amp/KEYLOC/powered sub setup.

I’m planning to do this myself, so I’d be interested in hearing from anyone who has:

• tried fitting a 6.5"/6.75" sub in the factory enclosure;
• measured the available depth/opening;
• confirmed how the factory dual voice coils are wired/driven by the B&O amp; or
• found a suitable adapter/spacer.

Any photos or other details would be very helpful. Thanks!

It takes like 2 minutes to pull the factory sub out. That'll tell you everything you need to know about this project.

There are posts on the forum of people wanting to upgrade the B/O sub speaker but none with a resolution for it. I doubt just upgrading the speaker would greatly improve it because it does not address the sub cutting power at 60% volume.

That said a stealthbox 10" sub mono block amp and keylock is not inexpensive but a huge improvement and worth every penny.
