Works as advertised.

Works perfect, ran 4 gauge wire but my amp only accepts 8 gauge inputs.

They do what they are supposed to do.

I needed a set of these to hook up 4AWG wire to my Powerbass Amp, they fit the terminals snugly and hold the wires nice and tight. No wiggling loose and no shorting across the amp power and ground terminals! At first I thought these were expensive, but this is a solid solution for landing 4AWG power and ground wires to amps with smaller terminals. I also appreciated that you can put the red cover on the power wire and the black one on the ground wire, makes things look tidy and it's easy to see what's what.

Just what I needed.

I needed this to fit the smaller factory power wire into my postive battery terminal. This did the job perfectly. If you just can't quite fit your wiring or want a very clean look at your terminals this is the way to go.

The included red and black bands were a nice touch, making this universal as well.

Top Notch quality

You can just tell quality metal when it's in your hands. Love the rubber boots that go around both for insulating purposes and to define positive from ground easily. Super quick to install, probably 5min tops. Just strip insulation off of the lead you're putting it on, put the bare wire end into these handy adapters and screw down the Alan key.

Outstanding Value

You can use these for the positive lead or ground. Red and black rubber identifier rings come with each one. I use on all of my amp installs.

Love this product!

There's not really much to say about this product other than it does its job very well, I'm very satisfied, and do highly recommend this if you are looking for a secure and clean connection into your amp.

2nd pair just as good as my first...

These are a must when I run 4AWG wire to my PowerBass amps. This is my 2nd time buying them because I put my old ASA1100.5 in my son's car when I bought a new amp. The terminals are way too small to directly land 4AWG, but these are perfect fits for the job and stay nice and snug. Remember to order 2, 1 for power and one for ground. They come with color-coded bands so you can easily mark power or ground wire when you land them, plus it just looks clean compared to trimming the wire to fit the smaller hole. My old have been worry-free for years, they just plain work.

Great choice!

This was a great way to make it easy to connect my powered subwoofer. The terminals are spot on. Thanks again Sonic.
