Before you start, you should first loosen and pull the negative battery cable away from the chassis. If your speaker doesn't have a cargo trim for cabinets, remove the two screws holding the bracket in place and gently pull the bracket off to reveal the body wire harness connector and disconnect it. After that, unscrew the four nuts fixing the grille to the back of the bracket and take it away. Take out the four screws connecting the speaker to the front of the bracket and remove the speaker. If your model has a cargo trim, begin by unattaching the negative battery cable, next remove the trim piece from the rear panel and remove the body harness connector from the speaker connector receptacle. Disconnect four nuts holding the speaker grille to the rear of the trim panel and then take away the grille. Take off the four screws keeping the speaker in place on the back panel trim and lift out the speaker. If installing without using the cargo compartment trim, set the speaker on the lower rear part of the bracket, position the grille and secure everything with 2.2 Nm (20 in. lbs.) nuts. Attach the body wire harness connector back, position the bracket on the rear panel reinforcements, attach with the two screws at 2.2 Nm (20 in. lbs.) and only after that, reconnect the battery negative cable. To do installation with the cargo compartment trim on, attach the speaker to the rear part of the trim panel, use four screws to secure it at 2.2 Nm (20 in. lbs.), place the grille over the speaker and secure it with four nuts again at 2.2 Nm (20 in. lbs.). Attach the body wire harness connector again, set the trim panel into place at the back and join the negative battery cable once more.
