Hi I just got the system and had the dealership install it so I wouldn’t accidentally mess anything up and when I got it back couldn’t really tell a difference that I even had the sub installed so I got the control knob and am getting no changes at all with the control knob. I flipped the second switch so far which made it slightly better but no real strong difference, so do you have any suggestions to have the subwoofer feel a little stronger. I’d greatly appreciate help from anyone else as well.
