Its got two inputs, depending on what kind of receiver you have. If your receiver has a sub pre-out, then you can use an rca cable to hook it up. Otherwise, you’ll need to use the speaker-level inputs, which basically means using the sub as a pass-through to the speakers. It then takes the signal as they are going to the speakers. Either way, it should work with almost any setup, and I’d be happy to help whoever buys it hook it up.
