Does anyone have any experience with the 400W Sony amp and harness for a 2017 XL from plug n play in CT? It looks like the answer to my wish to upgrade the stereo in a 4 and 5 speaker standard cab f-150. I have already built a custom speaker layout, see speaker thread, but feel that the sound could be a little cleaner.

Decided to dive in head first. I ended up purchasing the amp and harness setup that comes with a subwoofer converter. I will pull the passenger seat this weekend and finish the seat heater element installation, mount a bracket for the 8” powered sub, pull the center stack and install the amp and seat heater switch. With a little wiring for the sub I should be back together Saturday afternoon with the stereo and seat heaters finished. This should be the end of optioning this truck. Now to drive it for another 10years. It is 8 months old and already has 11,700 miles on it.

Well it is finally in and working. I purchased the kit with a LOC and added a powered compact sub. The sub received no speaker input. Returned the sub and purchased a second after we concluded the amp and harness worked as designed. Installed the replacement sub and still dead. Pulled the amp and harness today and moved the speaker input for the LOC from before the amp to after the amp and now all is good. A standard cab XL with Sirius and CD radio but no center speaker does not have the rear door speaker signal activated. The multiple dealers I contacted to activate the rear speaker signal played dumb so I just modified the harness. Tomorrow I will dial in the crossover point to the sub, decide if I want to kill the 80 hz and below signal to the front custom 3way speaker arrangement and reassemble the center stack. It has taken a while but from the initial listen it should be worth the headache.
