Just saw cut-outs in the deck lid in back. I did it to my car. Trace the speaker with a crayon or something (do not cut around areas where the speaker screws go and make sure you start cutting small, then trim to fit), drill a couple holes to make room for the jigsaw, and saw away. Just make sure you dont make them too close to the front since there is a metal bar. I'm sure many people have done this, let me know if you have any more questions.
