Factory subwoofer removal help?!

I searched but didn't find anything, can anyone help me with removing the factory jbl subwoofer in between the rear seats on an access cab? I cant figure out where the screws are to remove the damn thing! Any help would be greatly appreciated!

 

Down by where the power switch is, there is a panel. Kind if u shaped. That pulls off. Then you can pry the top of thd unit forward. That takes the top off. Then there are 4 bolts holding it in.

 

how to you pull off the u shaped part where the knob is? It deff doesn't just pop off with a screwdriver

 

Try to get your hand under it and gently pull from the side. Feel around, so will be able to get your hands in there and pry it off. I got pretty big nits and I got my hand in there.
