I am having a huge problem trying to hook my M&K Sub up to that Pioneer amp. If anyone has a clue, please offer some advice, I can get it to work, but the level is so low I can not really hear it at all. Even after adjusting the level on the back of the bass cabinet. If I switch speakers from AB to A or B I get a really loud bass feedback, I was afraid I blew it up , but all is ok. The left and right input RCA's on the back of the sub confuse me, as there is only on RCA out from my amp. Someone point me in a safe direction.
