I want to put a new system in my g35 sedan because If i have to listen to this bose shit ONE more day ill kill somebody. I was thinking doing 2 10 inch w7's in the trunk (custom install to make it look nice, my last car I just had 2 12's in a big grey box and it looked like shit.) Sealed, Ported? My friend told me it would be best to go ported........ Also, the stock head unit is a complete BITCH to take out in a g35. It's double din not to mention it's connected to the AC contol board so if you want a new radio you need to buy the AC controller..... parts alone would end up costing ~400 shipped directly from japan just to get the right trim pieces to make it 2 single dins. Couldn't I just add a LOC to the stock Clarion HU (6 disc in dash) ? Or would i be better off after spending all this money for custom install and the w7's ponying up for the complete HU conversion.... which would run me ~800 dollars more.
