Are there really no 6x9s that will fit. Anyone have a definitive mounting depth?

It would be very difficult. If you look at my pics above and in this write-up here, you can get a visual sense of what your working with.

It might be possible to make a spacer for one similar to what I did, but it would be a very tight fit to get the 6x9 on your spacer and also have the spacer use the factory bolt points (by having you spacer bolt directly to the door and eliminating the factory plastic spacer thingy). I think it depends on what your're willing to do and go thru in order to make it work. In my point of view, probably isn't worth the time and invest.

I dont have a definitive mounting depth, but the clearance is actually pretty good. Even with the generic Nissan mounting ring that comes free with crutchfield orders there is a decent amount of space. I was able to fit some Eclipse 5.25" in there fine. The center of the hole backs right to the guide for the window so you dont really have to worry about window clearance (i.e. you'll know if theres an issue immediately). If you use one of those Nissan speaker spacers they have on ebay I think you could mount practically any 6.5 or 5.25 in there fine.

Here are some pics of the non-bose speaker and mounting depth. Its hard to see in the pics but the available depth using just a schosche ring is a fraction over 2". With a spacer you've got another 1/2" to 3/4" (notice the depth of the stock speaker).

Also, I don't like using MDF mounting rings/spacers. I've used them in the past and in the three cars I've put them in moisture caused them to expand considerably. I wish I had pics of the ones I pulled out of my Altima, they went from 1/2" to 1" bulges in between the screws.

I don't get it - doesn't it look like that oval opening is made for 6x9?

It will be difficult. To do it, you're gonna probably need to make a custom bracket / spacer for it. Not really worth the time and money in my opinion.

I don't know...6x9 would be pretty damn awesome...

Great Front Door Speaker Instructions
 

Thanks for the photos / install instructions for front door speakers. I just installed a set of Polk Audio 6 /2 inch DB651s and some DB1001 tweeters. I had the base stereo and these fit well with the adapter brackets provided by Crutchfield. Sounds great! Small investment for such a big improvement.

Very useful post....ill be needing this.

I refer my customers to this thread all the time. Thanx for posting this.

I am currently trying to remove my door panel. Everything is the same than you except on my door I have a SRS Airbag logo and it seems to be stuck there. Everything else came out without issue. I am wondering if there is a screw in that place but I am not able to see it at all.

Ok I got it, there are 2 more screws on the door equipped with airbag.

Thanks for the post! Is it possible to remove the black door handle pieces (but not the handle itself) without removing the door panel?

Thanks in advance...

Not quite following you; are you referring to the actual door handle or the black switch panel in the right-up?

The actual door handle, specifically the three black pieces behind it. One piece is behind and surrounding most of the handle, the middle piece is the one removed in the write-up, and the front piece merges with the air vent. I want to remove all three pieces without removing the door panel, is this possible? If not, could someone post a pic of the back of the door panel in the area of the handle, so I can see what is needed to remove these plastic pasts? Finally, if I do remove these parts temporarily (but not the handle itself) and reinstall the door panel, will the handle still work? Thanks...
