speaker size on the 370z
 

what are the spekaer size? i Know they have four speakers, but are they 4, 5 or 6 ïnches? mine is a nismo and only came with the speakrs in front

Speakers in doors are 6 1/2", tweeters in the dash are 2" which you'll never find (I put 1" in) and rears are 3 1/2" (at least that's what I put in and there fit perfectly),
