I have a 2020 Kia Forte GT. I want to keep the stock radio. I have a Alpine PDX F4 (4 channel for the door speakers) 100 watts per channel and a JL Audio JX 500 1 channel going to the sub 500 watts rms. Now I just want to know the line converter to get while keeping the stock radio with this system. I would like to get one where I can have the best output signal as possible. I was considering this product. What do you guys think?
