Hi guys im new here and dont know a whole lot when it comes to selecting speakers and amps.

The car has 6.5 in the doors 3.5 in the dash and 5x7 in the rear package tray from the factory.

Ill be keeping my Avic z3, and my two 10" alpine type r's from my last car and will be buying all new components and amps for this build.

Im looking to spend around 200 for front components and the same amount for the rears.

Im deciding between the jl xr650 csi and the infinity kappa perfect 6.1?

and then for the rear im not sure if i wanna just throw a 6x9 in the back or another set of 6.5 components?

Would a set of 6.5 components sound better then a 6.5 coaxial and a nice 3.5 in the dash?

as for amps im thinking of the alpine pdx 4.150 and the pdx 1.1000?

What do you guys think?
