Are you going to put in a amp? Most good speakers will not sound good with the 13-18 watts they get from just a radio. If you do not plan on amping your speakers look at the Jl audio Tr's they have a good even sound for low wattage. Stay away from 3-4 way speakers like from pioneer unless you want a ear bleed.. a speaker that say 200 watts in the back would want a min of 75 watts rms to sound good..
