@grannyring , I agree to bare wire, only what to do with that 3/4" thick sausage LOL? I doubt that it's going to be cooperative to the screw-in posts of amp or any posts technically. Need to check if Mapleshade doodz took such thickie from near-by power transformer...
soldering is out of question simply because you will rather need an electrode welder instead of soldering iron.
