Hi, I just bought an insignia reciever from best buy. I've got all the speakers setup and it all sounds great. Quite a step up from my old stereo with 2 channel output, now i got 5.1 , but anyways, I was wondering how or even if i could connect this sub i have. It's actually meant for a car, but I thought maybe there would be a way I could use it for my room because I don't have an amp for my car, so the sub is just sittin' there. The sub has the red and black connection slot.
