How I greatly reduced my subwoofer rattle.

[Valhalla]

I have the B&O. I am not ready to spend money on the upgrade for it. Mostly because I'm saving for portals and two sets of 40's.
My biggest complaint is not the muddy mids and lows. Mine is the rattle that definitely has gotten worse with time.
I pushed on the panel wile playing some music that made the rattle particularly bad. I decided to put some foam rubber sheeting between the enclosed the panel.
After pulling the panel I discovered one are of the sub enclosure seemed to be where most of my rattle was emanating from. I removed the bolt put a small square of the rubberized foam between the plastic box and the body. This almost eliminated the bulk of my rattle.

After that I made a layer of the material between the wheel well and the panel. I re-torqued the bolt and viola.
It is much more tolerable.
Side note, I get a cleaner sound on mine by flattening all the eq settings, turning the volume to the highest setting I'd listen at then bringing the highs up to desired level. Next I bring up the lows. ( on this system it isn't much) Then I bring up mids. ( That is less than my lows! )
I get liveable sound this way.
Here is the material I used.

How hard is that panel to remove without breaking something? I've been thinking of doing this to mine and adding some kilmat to help with the rattle.

If you have trim tools super easy. Take the covers off the floor "D" rings and remove all 8 10mm bolts. Use trim tool to pry up center rear trim. On my two door i did not completely remove the side panel. I took all fasteners loose to nearly the front then lifted the rear alignment tab out. There is a small piece of trim on the window side of the side trim panel at the rear roll bar that locks to the side panel.

Where did you purchased the rubber foam material from?

It was packing material for a purchase I made. It was thick and resilient, so I saved it to repurpose it.

There is an open TSB with Ford for all 21-23 with B&O to address subwoofer rattle as it pertains to the mounting bolts. Take it to your local dealer and have them work on it. I’m having my dealer do it this week so I can let you know if it makes a difference. I currently have a bath towel shoved against the outside of the panel to reduce the rattle.

I got the same TSB done. It went from bad to not great.

That is the bolt I tightened I'd say.

I took mine to my dealer for this issue week before last and they basically just shrugged after looking at it for two days and said there’s nothing they can do. At least they didn’t charge me for it.
I have Killmat and poly fill on the way to try and fix it myself as soon as I get time to take it apart.

Once the panel is off it is very easy to get to the offending nut.
