Hooking Up To A Subwoofer
Can I use the SoundPower system with a subwoofer?
Yes; often, you will not need any extra parts. Most (but not all) powered subwoofers have speaker-level inputs and outputs. Look for a set of red and black springclips or binding posts. To make a subwoofer speaker-level connection, just hook up the sub via your SoundPower's outputs, then hook your speakers to the subwoofer.
If your subwoofer only has an RCA input, you can still use it with the SoundPower system by adding a VR31A Audio Receiver, which has a RCA (line-level output.) If your subwoofer has left and right RCA inputs, get the VR38A Stereo Audio Receiver instead.
