Best 6.5 " car speakers?

[mostlpeoplelarelfools]

I am looking to redo my stereo. Have a nice Kenwood head unit and a pioneer amp that puts out 4 channels @ 50 RMS per. Looking for 4 6.5" speakers in the $40-70 range to throw in. Lot of speakers out there and I don't want to buy garbage. I would appreciate any and all suggestions. Thank you.
