I really like Polk audio speakers, good all around, plus clean tight Bass response. They are a bit pricey, but well worth it,,, but, your radio may not have enough power to drive them? ask around.
My 2nd choice is Pioneer speaker, best bang for the buck, and don't require a lot of power to drive.
Cheap, no name speakers could be loud, & tinny sounding, as the other poster mentioned.
I used to also use Jensen speakers, they're like the Pioneers, but I don't know if they're still around?
