well at the time of install i was doing more than just rewiring my amp, i was painting my interior so i removed all the panels and the seats anyway, but yes i think you have to remove the rear seats to get the side panel off. one of the brackets that holds the back rest in place has to be removed to get the side panel off, which is held on by some push snaps. the bench comes out by removing the 12mm bolt in the back and pulling the whole thing upwards til it pops out of its holdersYes coupe, I'm assuming you had to take out the seats to take the panels out?
