My first intention is to disconnect the wires from the Roland speakers. I'm building a cab with two Eminence GA10's in (8ohms). Would I be correct in thinking that I could wire one speakers leads to a jack socket (which I could insert in the backboard of the Roland amp), the other speakers leads to another jack socket (again which I will put in)...then run speaker cables from the amp sockets into the speaker inputs jacks. The Eminence speakers would be wired as per the Roland ones are now. I wish to keep the sound of the Roland's chorus. Am I talking rubbish here ? This is my first foray into amp 'modding'.
