I'm not selling any of the equipment so no cables.. what you get is the enitre box/build itself, the front face all carpeted etc.. If sat fully flush, it'll go from the rear of the back seats to an inch or two before the flap line in the boot. So you still have the access to the flap part.
All you would need is your sub (10") and amplifier and it's relevant wiring kit. All the little holes to run the wiring and what not are already made so it's as said, shove and play lol.
