(used for 2 12'' subs in parallel)  I ran a 50 hz tone at 80% volume (Pioneer head  unit). The highest voltage reading I could get was 15 volts. That is with the gain tuned all the way up (reading 0.2 Volts on the amp). I should set the gain to 44 AC volts.  ( V = the square root of (1000 rms x 2 ohms) ) The subs are disconnected. What am I doing wrong? What could be the problem that I can’t get the volts to 44? Thank you.</p></blockquote><p></p>
