Hi Norman! It seems that you don't have an amplifier there. What you have is a preamp. A preamp is a "controller" that goes before the power amplifier and it basically controls the signal (volume, bass, treble, pan etc.) and input and has one output that goes to the amplifier to made loud. So you need to get an amplifier to use with the speakers. Hope that helps. If you need any general advice on what sort of amplifier you might need, please ask along with the details of the speakers you plan on using.
