So you just wire that to your speaker wires and plug into the amp, then itll convert the sound through the amp and to the speakers?? What about the remote lead for the amp where do you source that?
i connected mine to the back of the headunit, took the original wires out which go to the speakers and fitted this in its place, as had a 4 channel amp powering the speakers,
as for remote wire i
think you use to black wire (thin one) from the back of the headunit,
just double check using Adam R link in his sig,
