i need to order 2 terminal cups for the boxes i built for my 10's. the manufacturer recommends 5-way binding posts which they sell at crutchfield. my question is, can u run a normal speaker wire all the way through into the box, because my subs have like a spring-loaded hole that u push the bare wire through and it tightens up. so my question is, can i run wire through these, or do i have to connect it to a female end or something like that. kinda confused.
