I have some older CerwinVega speakers that have push pin connectors.
Now heres what I don't know

.
Can these older push pin connectors accept 12 gauge wire
Because I would like to use them in a second zone stereo and i have a 65 foot run almost and a 70 foot run so i need to use 12 gauge wire but I don't know if those push pin connectors will accept such a thick wire

.
I have always used 18 Gauge wire with and they were on a short run but now i don't no please help me

.
