Bc it fit my measurements for my subwoofer box and crutchfield is a reliable source that my family has been buying from for years [ Austin  Dec 27, 2018 ]
Because it has the metal binding post terminal.. The terminal cup I currently have on my set-up is all plastic that started to melt when to much power was put through it [ Jacob  Dec 01, 2018 ]
Building my own subwoofer box [ Daniel  Aug 16, 2018 ]
Built my own sub box to fit where I needed it to go. You need one of these when ya do that. [ Vernon  Aug 15, 2018 ]

The one on my existing box melted and has had connection issues ever since [ nolan  Nov 28, 2017 ]
After purchasing a pair of Kicker 8" sub-woofers, the instructions included dimensions to build boxes. I decided to make them a little nicer by adding these excellent wire terminals. Between carpeting the boxes and these speaker terminals they looked very professional! [ Joseph  Sep 21, 2017 ]
Looked the best for building my box [ Jared  Aug 24, 2017 ]

Banana plugs are the shizz, and this one looks high quality. [ Dean  May 11, 2017 ]

Best looking one and built nice [ JEFF  Jun 24, 2016 ]
I've used this terminal before, the quality is good. [ Adam  Jun 09, 2016 ]

2 questions already asked

Will this work with banana plugs?
[ Mally  Jun 05, 2019 ]
1 answer
Yes it should, I didn't use banana plugs, I just solder the tips
[ Nelson  Jun 07, 2019 ]
Do you sell one that has 4 connections?
[ Thomas  Jun 20, 2015 ]
1 answer
Why do you need one with 4 connections? I can't see a need to run two amps to a single speaker enclosure, and you can wire the inside of the box in either parallel or series, for a dual voice coil, or a single. If it's something you really need to do, then install two of them...
