Suggestions on speakers for 08 D22

[Luke991991]

Hey guys I just got a stock standard 08 D22 and it didn't come with rear speakers. What speakers can I fit in the rears without adding MDF or cutting new holes? And what speakers can I fit in the fronts?
Cheers, Luke

What about the fronts? Because I wanna upgrade them to a lot better ones.
And do u know the clearance depth in the stock rear speaker holes?
