Report "I have a lfa series 800 watt amp. Everything works fine, I just want to know what the knobs mean and how to adjust them for best sound quality. I'm running just a factory stereo in a 03 gmc sonoma. It has built in eq as well. I am pushing two 12 ,s. One a kenwood bass plus and the other is a comp 12. Please be as detailed as possible. Sorry if this is a dumb ? Thank you"
