Hi everyone, My friend has a 97 Nissan Altima. He put an aftermarket deck in it a while ago and we just recently realized his front right speaker wasn't working. We pulled off the door panels yesterday and swapped the left front for the right front and it worked so we determined the speaker just needs to be replaced. He's not really into car audio(much to my chargrin) so he really doesn't care about what type of speakers we put in. The one thing I'm unsure of is the speaker size. It looked to me as if they were 4x6 but Crutchfield says they are 5x7. I've seen other sites confirm they are 4x6. I had 5x7 speakers in the rear in my old car so I'm familiar with what a 5x7 speaker looks like size wise and these seemed smaller. At any rate, can anyone confirm what size the altima takes? The other concern I have is that the mounting depth looked insanely shallow so I'm not sure if I'd need to make a spacer to give it enough clearence.
