How to hook up 8awg wire

[Irocthestreetz]

I've have my soundqubed hdc315 d2 hooked up to 12awg cca wire using wire nuts, which I know isn't preferred but I can't find 8awg butt connectors anywhere, and I don't have a terminal on my box. How do I wire this properly to 1ohm at the amp? Also powering my sub I have a soundqubed sq2200.2 and I'm wondering if while I have my sub out if I should hook up some 8awg ofc wire? Or will there be no difference in supplying the power to the sub? Thank you.

I drilledt2 holes in my box for bolts and did this. I used lugs instead of these crimp style connectors.

12g is fine too.
