Hey all new poster! and great community here!

I have a 2017 rdx (with ELS) and was wondering what you guys have used for speakers upgrades. I am speaking mainly about the front and rears. In regards to upgrading the front speakers i was looking at options for a component set with low impedance (close to 2). I have two issues one finding a set with a low ohm and finding one with a cross over that will fit. Have any of you just put the cross over in the door vs in the tweeter pod (not sure there is much room).

I was looking at the Infinity Primus PR6510CS they have impedance (2.7) and fits in the factory location.

I also have a set of Apine 6.5 speakers with build in tweet that will fit in the rear but they are 4 ohm? Any issues other that lower volume?

Thanks!
