I have an LS and would like to add a sub in the factory location because I need the whole cargo area for hauling stuff for work. Is the factory sub box behind the interior or where can I get one? What would be the best 8" sub/amp combo for some added bass? Thanks

 

nobody?

 

1) Yes the factory sub/amp is behind the left-rear interior panel.
2) I see these used on ebay, but I would check out some of the alternatives on this site. Good stuff here! :)

 

I meant as in if I dont already have the factory sub, is the box behind there or just empty space?

 

just empty space back there if you dont have it stock.
