what passive crossoveryou usng? if its the current 3 way one from maplin then just plug the two wires + and – from the input (1/4in jack or whatever your using) into the ‘in’ part on the crossover then connect the T,M,W to the tweeter,mid and bass spekers. the A output sends a full range signal, so you can ignore that probably,
this worked for me the other day,
hope it helps,
