Default Anyone tried replacing their B&O Subwoofer?

B8 guys had a lot of success with this:

wonder if anyone here has done it to its B9?

Thanks!

I'm interested in this too. My B9 sub rattles the deck, so I need to pop it open and wedge in some sound matting anyhow. I did the sub upgrade on my B8.5 and it was great: that shallow mount B&O sub was no match for a 10" Pioneer.

What did you do with your B8 and how did you like it?

I find my deck rattles A LOT too... even after doing some dynamat...

B8 was a lease. But I was over miles, so the dealer bought it as a used car.... some financial hijinks.

I loved my B8. Great car. Definitely getting long in the tooth technology wise, though.

I'm going to guess most of the rattles are the hard plastic B&O speaker grills. I found most rattles in my B8 were because of crummy plastic clips that didn't hold trim down hard enough. So I would literally take pieces of rubber and shove them under and around connecting points. Usually did the trick.

Did you find removing the rear deck for dynamat to be easy?

Yes its pretty easy and exactly the same as the B8.

Only thing I noticed in going to the other thread is that the Pioneer speaker used has been discontinued. The replacement is now the Pioneer TS-W261D4. Hope this helps.

That's basically the same speaker so that'd probably be my first choice. I'm going to assume the B&O still runs at 8ohms and.... maybe... puts 150-200 watts to the sub... which will drive this speaker decently

There is one difference....

The OEM b&o sub is DVC 8ohm... you wont find a suitable DVC 8ohm aftermarket sub... wonder if the OEM amp can support a 4ohm load...

The Pioneer (which I had in my B8.5) was dual coil and could be wired as 8ohms.

Edit: yeah, the one you linked can't be bridged (so 4+4 = 8) like the old one....

Edit Edit: I was wrong, the TS-W261D4 *can* be wired at 8ohms.

I believe it cant... you have two pairs of wires coming from the OEM amp expecting a load of 8ohms each pair... how would you wire it?
