Car pc build -Speaker setup

[zimon14]

Hey, After months of putting off the car pc build finally finished and got it all working.

 

But now I have two questions is there anyway to link the steering wheel controls to the car pc?

 

And also looking at this setup for the speakers but never done a speaker upgrade before will these work/ sound any good?
