pretty easy, hardest part is getting the centre console trim out so you can undo the cables inside the car, was a right faff last time I did it! main thing to worry about is if the cables are stuck in the metal guide tubes under the car, if they are then you'll pull the tubes out with the cables. its not a big deal if you do, just gotta lift the rear carpet up so you can thread em back in again. Best to do 1 side at a time, so if you do yank the tu8be out you can use the other side for reference getting the tube back in again!
