I honestly set it up the way the instructions told me to. I’m sure the settings they give are more on the safe side and I really didn’t want to blow a speaker out so soon. I haven’t used a volt meter to fine fine tune yet but I just might when I get time. Also my remarks regarding the 602 as having a lot of base is based on previous speakers biketronics Titans 7.1 they were great at mids and highs on the freeway.
