Your speakers are in your rear doors 4 1/2x 4 1/2size.Just take the 2 wires from both speakers and wire them up.2 wires per side of amp,or if one sub just 2 wires.Trying to help you.I got two subs in my truck an 8 in the back with 2 amps,bass cap,fuse panel in mine.And a 10 between drivers seat custom box I made.

 

Got any pic's of the center console box?:drool2:

 

Sorry I dont.But it is square 1 cubic foot,speaker up underneath box facing down.It is grey carpeted with a small box on top.Plan on cutting a C out of diamond plate for cummins and mounting it in front of the little box.
