Important differences between 06 and "07 Classic" Silverado?

[drakeG4]

My parents got me a 2007 Silverado Classic to replace my '02 Explorer. I want to put a decent sound system in the truck since its stock system doesn't sound nearly as good as the stock system that was in the Explorer. My main worry is the sub box, I was thinking about getting this

I have heard the 2007 classic is essentially the same truck as the 2006 Silverado so I figured it would fit. Anyone have any idea about the compatibility before I get it? Also are there any other major differences between the two that I may need to be aware of if I do other things to it? i.e. would external parts (bed covers, brake lights, etc...) made for the 2006 work for the 2007 classic?

If that subwoofer box doesn't work, what would be my best option for this truck? it is a hybrid so boxes under the back seat is a no go. It is to my understanding that the center seat is removable so that could be used for a box if this custom box doesn't work (it is made to fit in the center anyways).

Yep, the 07 classic is pretty much identical to the 06. My friend has one and he always has to select 06 when searching for info on his truck. Most sites don't recognize that it was a split year for the trucks.
