Hi I'm wanting to install 2 12" alpine type R's and a Hifonics amp in my 2019 Kia optima. I want to keep all factory settings and radio. I've installed systems in older cars when I was younger. When I wanted to keep factory radio in my cars I would buy a convertor and run off my rear speakers then run remote from fuse box and power from battery, however the amp I want to install now is 2000ws rms and requires a better power source, like maybe a extra battery in trunk. Another thing that would be different is the power wire calls for 0 gage and I've never ran that thick of wire in car. So I'm looking to see if y'all have any recommendations.
