So heres the deal. Went and put a jl 12" sub and a kicker dx125.2 amp in a 13 jeep wrangler unlimited by a pro shop in scottsdale (audio express) and the sub doesn't turn down with the rest of the system. They said that was normal with the stock head unit (430n). Didn't think about it and I said ok fine and left. It's starting to get annoying and I am starting to second guess if it is normal. Is it? Also, they didn't set the gain so I am self adjusting it and have no idea what I'm doing.
