I currently have 2 Sony SACS9 subs connected to a STR-DN1050 receiver. I have them connected via the 2 sub out lines. I have no idea how to properly setup the speakers. I have a 7.2 setup and used the auto calibration option with the receiver . I don't really hear much of a bass sound from the subs for whatever reason. What should I have the levels set to on the back of the sub? Should I have it set to reverse, or normal? The overall sound is good, I am just wondering how to kick up the bass a little. Again, I am no expert at home audio. If I need to provide more details, let me know. Thanks in advance to anyone who can help me out, and if I have posted in the wrong thread, please forgive me.
