sorry im a diamond whore, ive never heard speakers that i like better than my hexes. get the silk tweet if you listen to rock. amp is up to you, but i would recomend a 4ch and bridge it to 2ch becuase rear speakers are FTL and can be run off your head unit. alpine is always good too. especially if you can get an employee at best buy to hook you up. slip them a 20 and they will prolly hook you up.
