JBL makes a component speaker that might work (GTO 600c) its a 6.5 inch speaker that ranges from 40hz-23k hz leave the tweeter out and you might have a good setup. Its a bit pricey though...
I went with the Sony MEX-N5300BT and a set of JBL GX series speakers I like them so far however the speakers (GX602) do not fit properly in the front but do technically work.
Sony MEX-N5300BT:
