Hey guys, I just got a Series 3 Statesman with 164,000Km on it for $1900, needs a few repairs but other than that it's good as gold.

It's my first car so i wanna put a new Audio setup in it.
I got some 6.5 inch Fusion ones. And I wanna know How i can make them fit, Can i just buy the After market pods from AutoBarn and mount them in the door like that?

Thanks in advance.
