Subwoofer is 10" and self powerd. subwoofer fuse is good, speaker powers up and is not blown. Im using an RCA cable from the low level input in the sub to the sub pre-out on the reciever. I've tried using the other inputs and outputs on the speaker but nothing seems to work. the only other thing i can think to do would be to passively wire the subwoofer? but i would rather not.
