every site ive checked says that my rear speaking on my 89 maxima are 6x9s, i ripped the back seat off only to discover that they were circles, not oval shaped liket he 6x9 anyone have, or know of the speakers for the 89 maxima...thanks

 

on the 3rd gen, only cars equipped with the bose system had the 6x9s in the rear deck. otherwise, they're 6.75"s

and a note, your front door speaker size are 4x6. IF you did have the bose, it would have been 4" rounds.

 

if you want 6x9's in the rear, you'll have to get those bose brackets from somebody/junkyard. they mount from underneath the rear deck. i looked at a bose equipped maxima and didn't like how it looked, so i just cut my rear deck so they'd mount from the top. if you want 6x9's in the back, you have 3 options:
1) buy the bose brackets
2) cut out the rear deck to fit your speakers
3) fabricate a new rear deck out of wood and carpet and put that on top of your existing rear deck. cut holes in that and mount from the top.

i'm pretty sure most of the people on this forum will tell you to get 6.5's back there...but i like my 6x9's

 

yeah, sound was meant to be reproduced from a circular cone. i'd get a good 6.5 over 6x9s anyday.

 

yeah but how can i get a 6.5 when there 6.75?

 

most 6.5s will fit back there. my cheapo alpines i use for rear fill came with these bracket thingies that allow them to fit the 6.75" opening.

 

so if i get a set of 6.5's i should be ok right?

 

for the most part yes, but make sure it says so in the products detail etc that it'll fit the larger opening.
