Here are some test fitting pictures of the
JL Audio Powerwedge+ (10"). I had this one in my pickup and it was within 1/8" of the opening size so I decided to see if it works. I had to remove one small plastic bracket (nothing was attached to it - it is at the top left corner of the sub looking from the trunk area {see the folded down carpeting near the O}) that I have no idea what it does since nothing was attached to it.
View from the trunk:
View from back seat area (seat folded down):
Side connections to the powered sub:
As far as the install goes, here are the spec's, won't have any pictures until next week once I pick up the vehicle, but also not sure if there will be much to see other than the control knob for the sub and JL Audio Fix processor.
