Pathfinder with new Alpine, need opinions on speakers

[ScottReeve]

I just got the Alpine CDA-9857 HU installed in my '02 Pathfinder.

I would like to hear some recommendations on speakers to replace the
Clarion/Bose (can't tell which) is in there. I think it's Clarion
speakers.

The car will take a component system. So, I'm looking for a component
system and my price range is somewhere around $250.

I will eventually be hooking up my Alpine 3553 4/3/2 amp (it's rated at
50wpc).
Most likely I'll be bridging into 2 channels, and the HU will power the
rear speakers.
(no room for a SW).

I'm trying to avoid two things: 1) muddy bass and 2) overly bright
sound

Any assistance would be appreciated.

Thanks
