I recently aquired a '97 Jeep Grand Cherokee from a relative at a great price. It has the Infinity gold stereo system with 6 1/2 inchers in all doors. Since the truck is 8 years old, and I don't think my uncle ever blasted the radio, those stock speakers did not last long. They still have decent sound, but crackle with bass. I have been having trouble trying to find exactly what kind of speakers I should go with. I am content for now with the stock amp and head unit. I just need to figure out what speakers to go with. I am only so keen with stereo systems, and I do not know what to buy. 2 way? 3 way? 4 way? I would like something I could just plug in and go. I read somewhere that the rear two are bass? Should I buy different ones for the front and rear? Any help would be greatly appreciated. Thanks. -Chris.
