I know my problem has like 50 different starting points without being able to look at it. But I was wondering if anyone might be able to help me out with my problem. Long story short, I bought the N2 at Best Buy because of the killer deal I got on it. I had them install it which I was quite weary of, but the guy that did the install sounded like he knew what he was doing. He used the factory amp and used a amp converter to hook the amp to the new unit. I thought everything was fine and dandy, but have come to realize that the 'subs' behind the seats don't work anymore. I have tried to play with the settings on the unit, but aren't completely familiar with all the equalizer settings on the unit...and the instructions aren't much help. I also don't know if it was an install problem either. Before I started taking my car apart, or have BB do it, I am weary of having them do it again. I was wondering if anyone with the unit had any suggestions on where to start. Like I said, I know there could be 50 different answers to that, I just thought I would try first. Thanks.
