Hi, Just got my first ever sub and I need a bit of help setting it up please First off is settings on back of sub, 1.) Low pass cross over shoud it be set to direct with my Yamaha 1500? 2.)Auto on/off active/inactive? 3.)High pass crossover 100Hz or 80Hz? 4.)Sub Volume? (currently as shipped to me) Im using my yamm's YAPO to set it up, however I do have DVE and a SPL meter if thats a better way? when using the YPAO is sets crossover freq to 120Hz is that correct? it also counts my rears as "small" but they are not sat's so again is that correct? I noticed that when I took it out the box and just plugged it in bass was much louder and deeper than after the YPAO setup? Any advice very much appreciated D.
