you want to run 0 gauge wires from the amp to the subs.... thats overkill... 10 gauge is overkill... 16 or 14 gauge is fine.

you may want 0 gauge for power though.

 

ah, ok. thanks for clearing that up.

 

Skip the terminal all together.

 

think that's what i'm going to do. What should i seal the hole with?

 

Silicone

 

I sincerely hope that you understood that discussion was about your power wire from the battery and not your speaker wire.

Even 8 ga is overkill - most people run 12 when all they really need is 16.

Remember, the shorter the run, the smaller the wire can be.
