So I am trying to put a amplifier that i am going to connect my speakers to behing my 2007 350Z and the sub wont fit in the circle is there any way to open the thing up? ansd how? thanks

 

Are you trying to ask how you can remove the OEM Bose subwoofer mounting plate behind the driver's seat so you can mount your amp in the OEM subwoofer cubby?

 

If you are trying to put your amp behind the driver's seat then you will probably need to take off the metal plate that is for the stock subwoofer. You will need to pull the back panels and then you can reach the screws that attach the metal subwoofer plate. It's fairly simple and the back panels will pop off with some effort.

 

hmm ill give it a try! thanks
