I need I picture if possible where I am supposed to cut out for the rear seat to lock down. This may seem obvious but the spot they have doesn't appear to be correct.

 

Sorry I don't have pic, the rear cargo liner should have 2 cut-out section that allows the rear seat to be latched (for the JK 2 dr rear cargo liner). This cut-out are quite obvious to see, should appear the same as for the subwoofer cut-out. You have to remove the rear seat to place the cargo liner.

 

Remove the seat? Really? Good thing it came with instructions. How hard is it to remove the seat?

 

Rock it forward, then grab the two bars that go across the width of the seat and squeeze them together and it opens the latch and then you just lift up.

 

Sweet, thx
