Good 6 1/2's????

I want some 6 1/2's i can push pretty hard that wont distort. I want them to be pretty loud but it doesnt have to blow my ear drums out either.

Just enough that i can crank em up with the tops and windows off and still hear the music over my crappy singing.

I dont mind pushing them with a small amp but im looking to stay in a semi budget like ~550 for all 4 speakers...(amp not included in that price)

Can it be done and with what speakers?

get some 6.5 alpine type R's. GO to a local store like best buy or circuit city to get them.; they are pricier, but if they ever go out, you will just need to take them back there instead of shipping them. Trust me , ive heard alot of different speakers when i was searching for mine, but the price killed me so Im saving up.
