i have just been given the above sub to go with my recently purchased denon soundbar. the latter has a subwoofer pre out terminal but the sub has 4 sockets line in left and right and another two which i cant quite remember what they are!. any ideas how i could connect these two together? i'm a bit unsure. i have also been given a coax cable by the hifi shop ( i asked for a subwoofer cable). i am a bit lost here because i have never used a sub before. thanks in advance. hope someone can help! edit: i basically have one ouptut from the soundbar(amp) and two on the sub. do i just use a set of phono plugs?
