Just finished a box build, and I really didn't want to put a plastic speaker terminal on the box for multiple reasons. Just ran wire through the port for now. I see a lot of guys using threaded rod, and I'm just wondering how good that method is, and how you properly seal that after. I'm open to any other suggestions as well.
On another note, is 8 gauge wire sufficient for running 1500rms to a single sub?
Any feedback is greatly appreciated, thanks in advance.
