Hi guys, i'm just wondering if is possible to replace the factory bose sub in my rear deck on my 2003 g35 sedan for an EV speaker for vocals, i have plenty of bass in the trunk and im looking to get alot louder vocals, any of you guys have an EV speaker in place of the sub and if not how many inches is the OEM sub, i'm just wondering if is a direct swap

 

There's nothing that would make it impossible to do. Just rip it open and see how big it is then replace it with the same size.

Make sure it's rated the same etc. I am sure you know what you're doing there..
