Pihitin mo ang plastic nut ng amp binding post ng todo, dapat may makita kang butas, similar to your speaker's post, that would fit your plug. Kung wala, see if the plug fits the center hole of the binding post (parang idudugtong mo lang). Kung hindi pa rin kaya, find "crimp-on pins" na gold plated, which are available from Monster Cable, most likely even Quantum. Mas maliit siya at mas mura compared with solid copper-gold plated banana plugs.
