Custom box help needed
 

i want to build a 2" box to mount my amp,battery,subbox, and TV on.
i want to build it so that it hides all the wires that run to my components.
any help on how to shape the plywood so that it forms to the back of my seats and truck. my truck is a 2000 Blazer LT 4X4



ANY IDEAS?:icon_speaker1::icon_speaker1:

the back the seats are pretty flat. just do some measuring of how big of the equipment you want to put in and what you have space for. i saw something similar in a tahoe that had an enormous sound system
