What speakers will fit?
 

I wanted to know what speaker size fits in a 2017 Nissan 370Z Nismo? Speakers being replaced will be the two front door speakers, two dash speakers,two rear side corner behind the seat speaker. I was told the door speakers are 6 1/2",dash speakers are 1" tweeters,and the rear side corner behind the seat speakers are 3 1/2". Speakers being considered are Kicker KS series speakers will they bolt right in? Do you need adapter spacers for the front doors using Kicker KS series 6 1/2" speakers or will they bolt right in the doors? Are there subwoofers in the rear of the vehicle?

Anyone know?

Check out the crutchfield outfit my car page. They have a rather detailed guide for the 370z.

They list a detailed master sheet for the tools needed for modifications. The also have adapters and recommended speakers.

Sonicelectronix.com has a good guide as well -

Mine is an '09, but I don't believe there's been any changes.

I put 6 3/4" in doors with spacer (recommended), 1" in dash and 3 1/2" in rear.
If you got the Blose system, you'll have a sub in back. If not, no sub.

Front door speakers 5 1/4" Dash speakers 1" tweeters Rear side corners behind the seats 3 1/2"

5 1/4?????? Why?

Why not? There are equally good 5 1/4 speakers that will fit well in a good adapter or cut out.

Ok. Just seemed awfully small for the space.

I am looking for front door speakers that have the best fitment. I am open to any opinions on what speakers everyone thinks will fit best without using spacers. I am thinking about doing 6 1/2" speakers in the front doors though. What speakers would you get? What size?

You do or don't have the speakers yet? The 6 1/2 is the largest circle size you can fit, 6 3/4 is the most popular size as you can fit them in incorrect size adapters and spacers. You can also fit a 6x9 or 6x8 component speaker, these are not that popular anymore, but JL and kicker made some of the best when they were.

5 1/4 and 1/2's are generally aimed towards larger systems that have dedicated subswoofers and mid range drivers as they have deeper cones per depth, resulting in slightly tighter, more accurate low bass and mids. The larger inch or so may throw out a bit more bass as a "do it all" speaker though, thus 6 1/2's are recommended for basic systems.

I have not purchased any speakers yet because I want to know what speaker size will bolt right in and have the best fitment without using a spacer adapter before I purchase anything. I am considering the Kicker 6 1/2" speakers for the front doors. Any thoughts?

I believe the factory size is a 6x9. You will need an adapter to use any component circular speaker. There is no problem with using one, just make sure its the right size for whatever speaker you change to. The recommended size would be something smaller than a 6 inch. so yes, 5 1/4 is the most adaptable size.

Ok if a 5 1/4" speaker is the most adaptable size then I will get this size then. What vendor can you purchase spacers if needed for 5 1/4" front door speakers for the 370Z?

From my experience, you're probably going to have to use spacers.
The stock speakers are a joke in that they have an extremely small magnet. Once you put in aftermarket that have a good magnet, you're probably going to get in the way of the window.

The Blose speakers are 6x9, the base are round. 6 or 6 1/2. Something like that.
