I looked in my 2015 JK tub and there is a large speaker mounted in there that fills the entire thing. Isn't that where the jack is stored? Where else might it be?

Nevermind, I found it.

But just how do you get that speaker out? I want to mount my new ARB twin in there.

 

Right by the swing out door, between that compartment and the door. At least on mine it is there.

Edit: can't help with the sub relo, mine is against the wall passenger side.

 

I would just mount the compressor under the front pasenger seat.

 

There's not enough room for it under the passenger seat in a 2 door, or at least it doesn't look like it. That would be the best place I agree, but I'm afraid the folding mechanism would be in the way.

 

Ryan, do you have to move anything with that under hood mount?

 

It depends on the mount. I believe there are a few available that work with no or minor moving of anything.

Teraflex makes a bracket that will fit under the passenger seat. There is an install video on YouTube. Looks like a nice setup.
