Just connect the converter to the speaker output on the amplifier. The output on the converter is a line level output to two phono (RCA) sockets. This works for me because my sub has two line level phono inputs. Some subs have just one phono input and if this is the case then you probably need a splitter like this one https://www.amazon.co.uk/BRIEFCEC-Extension-Cable-Point-Female/dp/B097HJQYL7/ref=sr_1_21?crid=2DL00BG1ECMED&keywords=phono%2Bto%2Btwin%2Bphono&qid=1685451919&sprefix=phono%2Bto%2Btwin%2Bphono%2Caps%2C139&sr=8-21&th=1.
