How To Install An Amp and Subwoofer On A Stock Factory Stereo/Radio Using a LC2i Line Out Converter

I give a full detail layout of my setup, how to tune the lc2i correctly, and how to tune a stock head unit with a DD1 aswell.
Setup: 2 CAB 12's (2k rms pair) in 4.0cu aero, tuned 35hz.
Taramps HD3000
Skar Audio LP85.4
Clarion EQS746
Kicker CS 6.5s
Fosgate PPS6.5
Audiocontrol LC2i
Basic DMM to measure voltages from Lc2i and Clarion eq
Tuned with SMD DD1, and Real Time Analyzed with the Dayton Audio Imm6 Calibrating Mic and Audiotool App on a Samsung Galaxy Note9 using pink noise.
There wasn't too many full detailed videos on how to tune the lc2i, how much voltage it puts out, and more, so after a few months of experimenting, I finally figured out how to get the best out of the Lc2i. I'm sure I left out a few details, but for the most part, it sounds great!
