Great connectors
Size: 5 pairs
Just finished an overhaul on the stereo system. A couple decks needed new belts and the wife wanted a new cabinet for everything so just take it all apart and refresh. I ordered these plugs to make the backside wiring a bit neater . They are very well made and easy to install if you mess up the polarity just swap the arrel covers, easy peasy. Great quality and easy assembly. Did it improve the sound? Can't say that I noticed that but it is certainly as good and so much easier to connect speaker outputs. I would certainly buy again.

High Quality Banana Plugs
Size: 12 Pairs
Banana clips are high quality, I used 12 awg wires and had no issues. It secures into the plug with 2 small screws, you will need a flat terminal screw driver to install them. The quality was high and made a good connection. If I had to make one complaint it would be that I would tighten the gray piece to the plug and it always kept spinning, otherwise, excellent product.
