Product Research


General Overview: This rectangular 5-way binding post terminal cup will accept pin connectors, spade lugs, single and dual banana plugs, and bare wire up to 10 gauge. The posts are color-coded for positive and negative terminals. On the side that connects to the speaker, there are two 0.205" male quick-slides (will accept a 0.205" female quick slide). The wire can also be attached using the nut holding the quick-slides in place.

Note: Speaker wire and female quick-slides are needed to connect the terminals to the speakers.

Cut-Out Dimensions: The rectangular terminal cup requires a cut-out of 2.915" (wide) x 2.125" (high).

These were purchased because I am building my own sealed subwoofer enclosure. Another online vendor set me two different kinds before. I know Crutchfield will not mess it up, so I am ordering it from them this time. [ Gabriel  May 23, 2018 ]

2 questions already asked

What should you use for an adhesive along with the screws I don't want it to rattle or whistle?
[ Nunya  Jul 10, 2019 ]

So this part was installed into a custom built sub box. Depending on how thick your box is should determine the length of your screws. I used 1/2" wood screws, and liquid nail. But it already had a snug fit for the hole I cut and carpet that the box was wrapped in.
[ James  Jul 18, 2019 ]
I used liquid nail as a gasket and then screwed it down, much how the rest of the enclosures was constructed. This was also the first enclosure I built due to where I wanted to hide the sub, so my advice should hold little weight. I also built it keeping in mind that it was only going to be for a single 12, 500watt, low volume enclosure setup, I didn't have to build Fort Knox.
[ Travis  Jul 17, 2019 ]
you can try a multi purpose industrial epoxy adhesive or i hear super glue works well. be careful not to over use the super glue upon application.
[ chris  Jul 17, 2019 ]
It didnt rattle in my box but simple calking should do, or even put electrical tape on the back edges before screwing it down
[ Kevin  Jul 17, 2019 ]
You could apply silicone sealant or construction adhesive around the inside flange prior to inserting it into the box to ensure a tight seal.
[ Daniel  Jul 10, 2019 ]
Is this metal or plastic?
[ Jode  Mar 17, 2017 ]
5 answers
Everything is plastic, minus the terminals obviously, which are metal.
[ Cody  Mar 20, 2017 ]
It's plastic. Pretty good rigidity though. The terminals themselves are metal.
[ justin  Mar 19, 2017 ]
[ ryan  Mar 19, 2017 ]
[ Jansen  Mar 19, 2017 ]
Plastic I am happy with it
