I did the Hamilton premium upgrade for Android Auto/ Carplay (highly recommend).

So, I finally decided to upgrade my sounds.

Without fully doing my research, I bought an Audio Control LC7i pro and a Sony 8ES 8 channel amp.
I already have RF powered subwoofers (I bought both the 500p and the 300p 12, still trying to decide which one to replace my sony 10' xtreme box with a memphis amp.)

NOW, i am thinking i want to sell the AC dsp and Sony amp and get a Helix DSP amp (v eight, v twelve, maybe even v eighteen)
I figure the Helix can actually fit under a seat (the sony is pretty big).

My questions:
  • Anyone with the pinout to the ML amp (2018 LX)?
  • Am I able to let the ML amp to still power the center and liftgate speakers? Should I?
  • Can I use the powered speaker outputs from the ML amp to go into the Helix DSP amp?
  • Is it better to run an amp line to each speaker separately for tuning purposes?
  • Would replacing the OEM speakers give a bigger improvement?
  • Is an Audison amp as good as Helix for a green audiophile?
