Z3 center subwoofer

I have a 2001 z3 3.0
I'm searching for the center subwoofer because mine went out.
Any good leads on a place to find one at a decent price or specific size info would be greatly appreciated.
Thanks

Most people are currently replacing the single Z3 subwoofer with a 6.5" Kicker CompVT 65 4-ohm subwoofer. It requires some modification, but at least it is shallow enough to fit in the box.

Thanks a lot ! I found a few great deals online. You mentioned that I might have to make some adjustments to install it. Can you please go more into detail? Thanks
