Ok, I guess I was doing something wrong. Now my sub is independent from the rest of the speakers and not controlled by the fader. But, it is still very quiet compared to before. I guess Ill just have to live with it for now. I cant find any decent Car audio shops in my area that will take a look at it.
Overall I do enjoy the better sound that the Kicker Key provides my front speakers. Was it a PITA, yes, was it worth it? maybe, still undecided.
I think the PAC Audio leaves much to be desired tho. It works ok for the most part but theres still things about it that could be improved. Not sure why it cuts out when my phone is plugged in to Car Play and I send a text message. Also the SYNC system beep is a different tone.
I just wish there was a system that worked and deleted the Sony amp with no problems. I think our only other option is the DSR1 and it wasnt much better if any.
