I have an Bose Acoustimass 15 Home Theater System


I have an Bose Acoustimass 15 Home Theater System.... The problem is I don't have the receiver. I need to find one that is compatible and that will push enough OHM to the system...I read 4-8. Any suggestions would be great, google is not giving me much!!

I could be mistaken but I thought the Acoustimass system was powered through the subwoofer box, and that all it needed was a preamp, or source with a volume control.
