Hi someone help please i bought a 10 inch dual coil pioneer sub today and attached it to my Panasonic sa-akx72 stereo system not too long ago i connected the coils in parallel with the aid of a youtube video and it works but when i raise my volume beyond 26 the speaker starts making a sort of clack/clicking/poping sound can someone please help maybe i did something wrong? Its connected together with a superwoffer sub that came with the system and my system is 900 watts /9800watts well that's what it says on the box
