Fred Ryan Posted September 15, 2018 Share Posted September 15, 2018 (edited) I was sent a new amp for a R-112sw sub. I need help with installation. 2 wires (1 red and 1 black) are easy to swap out/attach. Where does the third wire attach? Does it need to be sodered?

Was there not three wires on the original amplifier? Was this amp from Klipsch? Quote Link to comment Share on other sites More sharing options...
