I have a 2020 with the Alpine system. I have upgraded the dash, front and rear speakers with tremendous improvement. I am still missing the "punch" with the increased volume. I went to a shop, I was told the route would be to add an AmpPro to add the amplifier, but I would lose the factory sub. I wanted to just add an amplifier to run the front and rear doors and keep the other speakers on the factory amp. To do that I will lose the fade control. Has anyone successfully added an amp to just the door speakers and retained the factory sub? I will learn to live w/o the fade controls, thanks in advance.
