Well the install was actually pretty easy, the wiring was very easy and it sounds better than stock, Its not amazing but a definite improvement.
Hardest part was clearing out the housing to make room for the larger speaker. I took some tin snips and went to town, the plastic would just shatter when cut....sooo it was kind of fun.
Wiring involved attaching the brown wire to the negative terminal on the speaker and attaching the grey to the positive. I had to cut off the little clips on the wires, strip them and then attach them to the speaker. Speaker had these neat little clips so it was a breeze to hook it up. There were two wires (black,red) which I tried attaching..didn't work, left them unattached.
OEM Speaker still wired in
Kicker wired in
Drilled out some new holes for the original screws and after a few test fits it sat flush. Screwed back in, re-installed the center console and boom...new woofer.
