    I have a 2018 with the factory JBL headunit and JBL amp.

    So far I deleted the factory JBL subwoofer and also replaced all the factory door speakers and dash speakers with aftermarket JBL speakers. I also added 2-10" subs and sub amp that are getting signal off the factory JBL amp.

    What I really need help on is what wires that are connected to the factory JBL amp need to remain active for the new Pioneer to function properly? for example antenna, gps, power, remote, etc.

    I want to replace the factory JBL amp with a 4-channel amp to power the aftermarket door speakers and have the new Pioneer head unit to power the dash speakers (crutch field recommendation).

    See attached factory wiring diagram of the factory JBL stereo amp. I know I will be reusing the factory speaker wiring for the doors but what about all the other wires that are currently connected to the factory JBL amp? I want replace it with 4-channel for little extra power and to get full range to the speakers. The factory JBL amp signals are filtered so I'm not getting full lows, mids and highs out of the aftermarket speakers.

    I would also delete my LOC for my subs. Run 2 sets of RCAs from the Pioneer headunit to the 4-channel amp and subwoofer amp.
