i tested it with just two 8 ohm speakers and no signal coming from the 16 ohm jack maybe the jack is fault

update - i purchased the jack plug and play, i can get the left side working with just the g12h30s and the right side with just the greenbacks but when i plug in to the 16hm jack i get no sound.

i do get all 4 working when its plugged in the 4 ohm mono (but that nets me 2ohms) as im using 4 x 8 ohm speakers.

any ideas?
Somewhere along the line, someone missed the fact that you're rewiring 4 x 8ohm.
That plug & play jack does not work for that.
See post #14.

i dont think thats right cause in the diagram it shows you can run just the right side you plug into it, then if you want the left only you connect the speaker to that input then a dummy cable to the right input so it only the left side is working.

yet when plugged in the mono there is no sound but if plug in the dual mono you get both speakers working but only at the 2ohm, so i think maybe the PCB is damage as theres no signal from the 16omh mono input
