2019 B&O Subwoofer Install Help?

[nathanks]

Here's what I did.

Sub: Dayton Audio RSS265HO-44, this sub is a DVC 4 ohm on each coil.

As you can see from the first pic, this sub fits in between the raised sections in the housing perfectly. Unfortunately the basket is too large for the housing so it will not sit flush without cutting the hole bigger. I didn't want to cut the hole any larger as it would have weakened the mounting structure. This means you can't re-use the original cover, but I think it looks great without it. I'ts only just slightly larger than the whole so I looked for a gasket I could use to move it away from the face of the cutout. I installed a 15mmx15mm EDPM rubber gasket (.059") around the sub with contact cement, then screwed it to the housing. Fantastic sound, but next step will be an LC2I and a separate amp. Until then, this kicks pretty hard

Thanks to everyone who contributed to this thread, it helped me decide what I wanted to do

Thank you for sharing this. The gasket under the lip was a solid idea. Where did you get that gasket?

I think that poster is located in Australia.

Yes I am.

I got the seal here but I’m sure you can find some on ebay. Just make sure it’s solid.

Did the bolt circle match between OEM and Dayton woofers?
Only the inner circle was off?
Did you push the connector pins out instead of snip the wires?

I may try this woofer, but wired in series to be 8ohm. Currently I run my B&O subwoofer at only a couple clicks off minimum loudness. Rather than deal with line level attenuation, it would be simpler to just quadruple the impedance. That should (theoretically) drop the sensitivity by 6dB, and that still may not be enough for balanced sounding bass.

I supposed I could also mount this woofer backwards, and then there would not be an issue with the inner hole circle mismatch. Another idea is to get the Dayton 8" woofer version, and then make an MDF adapter plate between the box and woofer. Could possibly then reuse the OEM ring and grille. The 8" response could very well be flatter than the 10" because the cone area is smaller for the small sub box.

No, the bolt circle doesn’t match, and since subs are fairly standard in their hole spacing I don’t think any would. There is no inner circle there is only one. Also the diameter between the factory holes is quite a bit larger which is Why looks kinda like it has ears on it.

I snipped the wires.

Where’d you buy the B&O I need a replacement for my car or were you just upgrading the speaker inside...

If anyone knows where I can buy the replacement /speaker that goes in the trunk or the from cover piece let me know...

I have a 20 Convertible with the B&O option so just replacing the speaker.

ok any word on where u can get a new enclosure?

 

[Mustang5ohMan]

Came out looking pretty nice. My only concern would be damage via items in the trunk.

Probably Ford dealer only.

When i look up part numbers over the internet, i don't get the B&O subwoofer shown for a 2019 model year, it shows only the older shaker subwoofer. :(

Where are you searching for it at?

But it looks like all sources found via Googke use the same database.

Do you want to keep everything OEM with the right-side trunk location? You could consider getting an enclosure that goes behind the rear seat. Here is a half-width enclosure that allows the right rear seat to fold down and thus you can put in a long item (even folding down the passenger seat if necessary):



Of course then you'd have the challenge of getting the cables over to it.
