I'm sorry that this is a repeat, but there are so many threads that just go down a rabbit hole, I've struggled to find a solid answer. I have a couple questions. First, I'm adding a sub and amp to my 2020 Ram Rebel with the HK system. I ordered a pac aph-ch03 for my system and was going to use line level inputs to my amp. After reading more, it seemed like the lc2i would be a better bet. My first question is would i have to use the anc bypass harness if i used the lc2i, or could i just get by with the lc2i. Second question, it appears that the aph-ch41 is the best route to go, but I don't want to spend the extra money (or additional wire runs from front to back) if I the lc2i is good enough. If i use the lc2i, i'll be tapping into the factory sub. Thanks in advance!
