I have a question about the base sound system in the coupe. I have heard it is terrible, and I will be replacing it. My question is: what are the factory speaker sizes? Also, are there any speakers in the rear window in the base system or is that just premium? I might add speakers there too. I need to know because I have a friend that comes across speakers for really cheap sometimes and I need to tell him what to be looking for. Thanks.

Front 6.5's with 1" tweeters
Rear 6.5's

The Bose system adds a 6x9 rear deck speaker as well.

Would I get better sound just by upgrading my speakers alone for now? I was thinking about upgrading to Pioneer Premier 3-ways in the back with 2-ways in the front. This alone should get better clarity out of the sound. What do you guys think?

Not with Bose, those speakers are run at a fraction of the impedence then normal speakers. Slap in a set of Pioneers and there won't be enough resistance for the Bose amp.

You'll need to upgrade the amp... don't have to get anything fancy, just a small 4 channel amp would do. Then you can give your new speakers a good signal.

Sounds good. So 6.5" component speakers up front and 6.5" in the back...
Also, is there anything under the rear deck that would prevent me from adding two 6x9s and maybe a 10 or 12" sub? My guy can cut perfect holes, so as long as there aren't lots of wires or strut bars under the rear deck he could do it. Is there even enough room back there to fit all of that? Thanks.

Are you sure they're 6.5s in the back, VQ? On the premium setup, the speakers in the back seat arm rests are only 4s it would appear to me and the rear deck uses 6x9s. I wasn't aware that they did an entirely different system and instead assumed they simply added two speakers. Of course, having never actually looked at the stock system, I've no idea.

I think we need a member here to get the final answer! I read several posts on other boards that the rear speakers appeared to be 4's but were infact 6.5's when the grill was removed. I believe the actual quote was "pleasantly surprised!" If someone has a free minute, and digital camera, could you confirm?

Not too sure since the site is blocked here at work, but I would imagine Crutchfield.com would have the exact specs.

You think the coupe is bad....go to your Nissan Dealer and listen to the 350Z'z PREMIUM SYSTEM (in the touring model). Now that Sucks!! [xx(]

Well I just finished installing a new amp and speakers in my coupe. The hardest part was replacing the stock 6X9's in the rear deck and running a new power cable from the battery to the trunk. I also had to cut out a spacer for the front door speakers. I didn't bother touching the 2 speakers by the arm rest in the back seat. It sounds great now! [phones]

Here is a picture of the old speaker I pulled out of the rear deck if this helps any.
