Why did Nissan put 6 3/4 speakers in the Max? The only place that I've seen that sells this size is Crutchfield. I went to Best Buy and Circuit City and they only have 6 1/2.

 

6.5's will fit just fine -- uscaraudio.com

 

you could have someone make a baffle for 5 1/4 if you wanted as well. there is one advantage to 6 3/4". for a 3-way front stage, it gives you a better range. a tweet, 4" and 6 3/4 is better than tweet, 4, 5 1/4. at least in my opinion...
