Great replacement parts!
Perfect fit for my 2003 Mercury Salt Water 150 2 stroke engine. Everything I needed was in the box.” “Good quality parts and saved me a lot compared to OEM.

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.
