Need some advice on terminals to use for my latest crossover build.

I want to run all the connecting wires underneath the board, leaving the components on top of the board. I thought of using binding posts for all the connecting points, but it becomes very expensive, as I will have 10 connection points.

Then I thought to use brass threaded rod.........I can just put a nut & washer on the bottom & on the top I could put a washer with a brass domed nut to give a better finished look.

What is the opinion of the conductivity of brass for these connections? I know copper would be better, but I have found that impossible to source.

I would normally use a terminal block from Mouser (538-38780-0110) which is zinc chromate plated screw terminals in a thermoplastic housing.

Any thoughts appreciated,

John
