05 4runner JBL, now after market

[Heybigguy91]

Hey guys running into some trouble with my aftermarket system. I know everything I have works because I pulled it from my previous car.
Pretty sure the JBL and pac harness is what is giving me the trouble but can’t find a way around it.
Ultimately everything works, but not how it should. I am using stock door speakers, Kenwood dx419 headunit, SKAR audio subs, kicker 600 mono amp, pac R.p4.2 TY11 harness.
I can get audio to all speakers but when I tune it, it’s all based on the front speakers setting. The direct plug for the subs from the headunit no longer works.

looking for ideas.
