Hi all, I am about ready to hook up my ava250 plate amp to my tempest sonotube. I have a duel input cup terminal on my sonotube.Im going to take one side of the tempest + AND - and hook it to one set of the duel input cups + and - terminals. The other side of the tempest I will do the same and put them on the other set of + AND - terminals of the duel input cup. Now this duel input cup has these gold plated bars connecting the + to + and - to - on the binding post, I am planing on leaving them there. Now I am going to run the red wire from the plate amp to one of the positive binding post on the duel input cup, the black wire from the plate amp will go to the negative binding post of the duel input cup.Will this give me the 4 ohm load I want? AM I doing this right?
