SRXECT 120PCS Wire Ferrule Kit Copper Crimp Ferrule Connectors Insulated Pin Cord End Terminals AWG(10 8 6 4 2) Gauge

Works well and seems good quality

Worked perfectly for me in my car audio setup. I used actual gauged wire as opposed to the oversized car audio cable and the ferrules fit nicely in it. It was super easy to use with the heat shrink sleeves I bought. I've had zero issues with connection, however, if your set screws are too tight, it will cut a hole in the ferrule. I've swapped amps in my car and they seem to be holding well in swaps.

These are life savers. So far, all crimps are tight and have passed tug test. Fine stranded wires become 1.

It’s really thin but get the job done

Better than wire nuts or trying to stuff wires in a hole

If you're installing an amp, these are wonderful. They make your install look very professional and are actually making it safer by minimizing exposed conductors. Great value, they fit perfectly and are super easy to install.

Sizes seem to be about one off. Used their 4awg on 4awg power wire and when crimped it was abit large so had some edges to fold over. Seem to work fine but try one size smaller for your wire and see if it fits tighter.

These are Perfect for setting up amplifiers, and you get a lot for how much you spend. I haven’t had any problems with them. I am definitely gonna buy again
