The next part was the part I was the most concerned about. Taking the door panels off of my new truck isn't something I really wanted to do, but I took my time and thankfully, I didn't mess anything up.
Kicker upgrade speaker on the right.
Next, you had to pull this cover off
Next, you had to pull out the plastic piece behind the door handle, and take out the controls for the power locks and windows. All the videos and instructions I found said to use a pick to pry up the little round thing to get to the phillips head screw. Mine did not have one of those, instead, I used the smallest flat blade screwdriver I had and pried that entire plate off. Once that was off, I found the phillips head screw and took the rest of the plastic trim off from behind the door handle. Don't know if all 2013's are like that or not. The power locks and power window switches came out relatively easy. Just carefully unplug everything once you have that out.
There were 6 torx screws (size 20) to remove. You will turn them and they will just turn and turn. Use a small flat blade screwdriver to gently pry under them and they will unscrew out. The fastener behind them (sorry, didn't get this detailed with my pics) looked like drywall anchors. Lift the door panel out. I set mine on a towel.
4 screws to remove the speakers, gently pried them from the door, new speakers were a direct plug in, then reverse the entire process.
Much easier job than I thought it would be.
Now, how much difference did it make? It's not any louder, but the dash speakers are much brighter and clearer, and the bass coming from the front door speakers is much more prevalent than before.
So the big question, am I happy with the upgrade so far? Absolutely!
Saving my money for the rear door speakers (77KICK41) and the upgraded amp (77KICK45).
