How Do You Connect An Amp And Subwoofer?
Hooking up a home audio subwoofer to an amp requires a few considerations: Is the subwoofer passive or powered? Are you using the amp to power the sub, or is the sub capable of powering itself? What type of output is available on your amp or preamp? Once you’ve determined the answer to these questions, you’re ready to get the necessary cable and make the connection. Use the “Sub Out” or “LFE Out” jack. This is a line level connection that requires a single RCA cable. This connection is for powered subwoofers only, as it won’t transmit a powered signal. Simply plug the RCA cable into the out jack on your amp and run it to the input on your subwoofer. You may need a Y cable to connect the one output jack with left and right inputs on the subwoofer. Alternately, use the input labeled “Mono.” Run speaker level connections. If you’re using the amp to power your subwoofer, as you’ll need to do with a passive amp, you’ll need to connect with speaker cable because this will be a powered signal
