Need some input on amp settings with for this mono block. Powering single sa8 v2. Do frequency settings have anything to do with sub life? I blew a sa8 v1.5 but amp was only 1/4 way up on gain barely up on freq.. Maybe too little power caused sum kinda distortion maybe? Any help would be cool as I purchased sa8 v2 d2 plus one of 007 customs and dont wanna blow another sub.
