Long time follower, just installed the full Kicker setup today. 19417166 is what my 19 called for. There are two part numbers depending on what radio you have. Had the full setup in my 16 and through it was easy to install, sounded awesome and could not wait since I got my 19 in Feb to get this. This set up is not fully plug and play and way harder to install than the older body style. Had to splice into the green/black wire at the ACM. In my option this splice should have a jumper harness for it for the price point. The harness looks like it is a multi fit harness. so it might have just been the way it is for my factory setup to get it to work. This system came with 2 amps and/or processors. One mounts to the rear cab wall, the other is on the sub box. Took nearly 6 hours to install mostly figuring out trim pieces and figure out how the rear seat came off to mount the amp and what worked and didn’t work. If I had to do it again it would probably take 2 or much less if things went smooth. Good news is the dsp and amps are tunable through the Kicker FlexTune app. Has a 5 band EQ, bass control, center position control and bandwidth setting. Only have had about 15 minutes behind the wheel with it and haven’t figured out the app all the way out to tune out the way too low crossover point. I first thought something was wrong until the really low note hit it was that low. It does take the bass out of the door and puts it in the seat of your pants so now you feel it, not just your leg next to the door and cleans the music up dramatically.
