I can't figure out what it's called! Wiring question?

Question

My alpine type-r 12" either didn't come with jumpers or I lost them and it's awful hard and awful sloppy to squeeze 2 wires into one terminal. There are little holes in the bottom about 1/4" in diameter but I can't find any wires to jump them with online anywhere. I know there is an end connector that looks something like this:
.._
./..\
{ || }
{ || }
.\_/
.| . |
(Well that was a pain in the **** to make)
I just have no idea what that end is called and I believe that is what is used for the jumper ends. Of course I tried about 600 variations of google searches and came up with zero results.

Anything would be helpful

Answer 1

That end is called a banana plug.
