Hi all, I'm about to replace the rear speakers of my Coupe. Can anyone give me some directions on removal of the side panels, Bentley is unclear. Also, can I make a 6 1/2" speaker fit in the well? I'm building a dual 12" isobaric enclosure for the rear and I'd like to have something a little larger that will bridge the gap in frequency response from the big woofers. TIA, Todd
