I am currently planning on upgrading the speakers in my explorer. I know virtually nothing about car audio so I am not sure which direction to go. I almost certain I want to install the 5250's up front but I dont know about the rear speakers? Should components be installed in the back as well or would a 2-way speaker suffice. I want quality sound which is the reason for the front speaker selection but I didnt know if not using components in the back would make a noticable difference. Any advice anyone could give me would really be appreciated.
