Hello everybody, my setup is a Skar rp1200.1 amp paired with a Skar SVR-12, as well as an LC2i due to the fact that I have the factory head unit. I installed this all myself a few weeks ago, and have been mostly pleased. After listening to my friends Kicker Comp R, I realized that my sub was playing a lot more notes than it should be. My subsonic filter is set around 24hz because the box is tuned at 32hz, and I originally set the LPF to around 80 or 90hz. I took the box out of the car and set the sub away from the car and played music, and noticed I could hear vocals and other music coming from the sub. I messed around with the LPF, raising it and even lowering it down to 50hz, I could still hear vocals even at 50hz, though they were quieter than at other positions of the LPF knob. I did the same thing with an 80hz test tone, turned the LPF down all the way to 50hz and could still clearly hear the test tone coming from the sub. Anyone know what I am doing wrong, or is this normal?
