W209 CLK 280 - Rear Middle Seat Subwoofer

[M.Khalid]

Hi You Guys!

I have bought a Mercedes CLK 280 (W209) Convertible with standard Audio system (I think it is called Audio 20).

I have seen these original Harman/Kardon subwoofer for sale on Ebay:

And I was wondering if I could fit one of these in my car? is it plug and play?
Has anyone tried to install this subwoofer into his car?

Thanks for your help
