im looking to upgrade the speakers in my non-bose g25x im sure its the same size speakers used in the base g37 sedan, i just need to know the size so i can order some speakers..

 

10". No one make speakers that will fit. You have to get a bracket.

 

10" for front and rear on a non-bose? that doesnt seem right?

 

Oh, non-bose? I'm not sure then.

 

If you don't have 10" speakers, I'm sure you have the same size hole in the door. You'll need an adapter of some sort to fit a 6.5-6.75" into that slot in the door. I doubt they make two different door panels for the different audio systems.

 

The door speakers are actually 11 inches. A 10 inch will fit without much work. The speaker looks unlike any other you've seen. I know because I replaced the rear deck speaker in my G37 sedan with a 10" sub. Putting a 12 inch in would require a lot of cutting of sheet metal.

 

Do you have the sub hooked up to an aftermarket amp?

 

Yes. I used a Sony xm-1s and a 10" JL 10W1v2. The speaker is shallow enough to fit within the trunk liner, and seems to handle the amp just fine. In this application the volume I need is easily produced by the little Sony amp. I also used a Re-Q for better bass at higher volumes. Had to use Dynamat on the shelf to removes buzzes/rattles.

 

Where do I find an adapter the goes from 10-11 inches to 6 inch, 6.5 or 6.25 inch size speaker? And also do I need a 2 ohm or 4 ohm speaker?? I just want to replace my current speakers, I don't want to amp them or anything additional....

 

I think the base audio system has 10 inch speakers in the door. I know they dont have the speaker in the dash, the tweeters by the exterior mirrors and the subwoofer on the rear shelf. I was in an 09 loaner today with no Bose and I must say, Bose aint the best but its a hell of alot better than stock.

 

Hmm I was wondering about this for a while too, let say we did find the bracket for the doors speaker, can we just buy any regular 6 or 6.5 speakers and stick it in there? I mean since the orginal bose speakers were suppose to be sub, wouldnt the bose amps filter out all the high freqs and just letting the low go through? So if i replacing those
10s in the door with 6.5 mid range, i still wouldnt hear the mid right? Also I'm thinking the stock bose have very lose ohms rating and the normal after market speakers are usually 4ohms

 

You'll have to fabricate it yourself unless you go to a custom sound shop and pay a nice price for them to make it and install it. It's a lot of work taking it all apart, measuring and figuring out what will fit. Then you have to actually make it out of something and weatherproof it.

Good luck. Whenever I do a mod like this I wonder afterwards if it was worth my time.

 

im sure brackets can be made out of mdf.. why would you need to waterproof the bracket?

 

If anyone knows if some places are selling premade spacer for the door speakers, please let me know. I know z-enclosure do it for the 350z and older infiniti, i dont think they do it for the newer one. Might just send them an email.
