Hi, I recently purchased some speakers and an AVR and I wanted to double check to see if I needed anything else as I want to make sure I can set everything up the day it arrives.

I was told that I would need speaker wire so I purchased these:

speaker wire: https://www.amazon.com/gp/product/B00N18VBSI/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&th=1

Banana plugs: https://www.amazon.com/gp/product/B00JFC9ALE/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Wire stripper: https://www.amazon.com/gp/product/B00CXKOEQ6/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1

Is there anything else I am missing or anything you would recommend I get?
