so I have a 2017 Pacifica unlimited and I'm looking to add an amp and subwoofer to the van. I'm familiar with older stereo installs but all this integrated factory radio stuff is new to me. I'm under the impression I'm going to need an inline converter for sure and I think it's called ANC bypass does anyone know if this correct. if not starting from the beginning what is it I will need to install a sub and an amp.. I will also be adding ground wire upgrades a secondary battery to the amplifier side of things. the equipment I'm using is 2 JL 10" W6 powered by an HD1200/1 amp all housed in a self built encloser. please I need some insight on this factory radio add an amp install!! thank
