I just bought an 08 350z and don't have alot of extra cash right now, so in the interim, I am trying to salvage as much of my system from my old ride as possible. I already have 2 Alpine Type-S 12's and 2 Infiniti 12" subs, that I upgrade to the Type-S from. I have an SPL 1200W max 350 RMS amp that is a perfect fit for Alpine S's. I really like the sound of this system and want to bring it into my new 350z. Also, this would prevent me from having to buy 2 new 10" subs and have 4 12"s sitting around collecting dust. I can build my own MDF box, but after measuring the back of my 350z, I can't think of a design that wouldnt take the entire back section of my ride. That bar in the middle is really making it hard to fit 12s in there stealthfully.

Does anyone have any pics or designs for 12"s in a 350?

 

zenclosures on ebay has a pretty sweet dual 12 box that fits at the forward part of the trunk.
