I am replacing some speakers in the Jeep but I really dont know what to measure. Do i measure the actual speaker itself, or the metal aroudn it that you put the screw through? I measured the entire thing and got 5 1/4" but just where the speaker part is, measures 4". So I could buy 4 or 5 1/4 but only one would work. Does that go for oblong speakers? Like 4x6? I really dont know and theres no indications on my speakers of what they are, if you know anything about this or know someone that does, please post! Thanx
