I connected everything by an installer. He did a great job mounting everything and installing it all but I don't think he knows how to do amp adjustments.
I managed get myself into the trunk and look. These are the 4 little turning knobs I see in the back of my amp. I have 2 sets of them, Front speakers and Rear speakers.
1: Low Boost (40hz)
Has settings between 0-+10db.
2: Filter- settings between 50-300hz.
3: Level- settings between 0.3v-6.
4: Subsonic filter- settings between 6-70hz.
I'm looking to make some adjustments because I feel my bass is to high and also the highs are too high. I tried lowering all equalizer settings but still can't get what I want.
