Thanks cjm, worked out fine. Velcroed the J&M unit to the side of the trunk box. Used a drill bit to hog it out so the hole would allow the cable thru, and, like you advised, carefully eased back the trunk plastic back to slide the cable down to the notched hole.
Much better than an 1 1/2" hole!
FuzzyWuzHe - upper left area by the hinge where the speaker/cubby hole meets the trunk side. Remove the screw and you can gently pry the trunk side outwards so cable can slide to the area you notched.
GLAD TO HELP!!!
Fuzzy do you still need the pics?
