Well I am looking to upgrade my front speakers becuase I have the stock ones now. I'm not worried about the back ones so they can stay. Should I get ones with the tweeters built in i think there called co-axials or should i get some components and tweeters. I don't really want to cut into anythin to mount the tweeters. Do i need to amp any other this or can i run it off the head unit (Pioneer DEHP6600)? Lookin for good quality sound that isn't too expensive. I am kind of partial to kicker products so are any of theres good?
