These are great. They fit in my mmats amplifier well and I like the way they have a lip on it so if it comes loose it will not come out and cause sparks on a ground etc.

  • Orientation matters, so does amp input depth, overall good buy Orientation matters, so does amp input depth, overall good buy
I'm used to modifying things I've bought to make them work. This one was no different, but was my amp's fault, not the adapter's. Perfect size 1/0 input, set screw is heavy duty and was surprisingly an SAE size, perfect size 4 gauge amp input. Adapter body itself is good and heavy, and once you make your cables with tubing and heat shrink, they look professional. The raised tip at the 4 gauge end of the adapter was just in the way of the set screw on my amp, which wouldn't allow an all the way tight connection. Basically the input on the amp wasn't deep enough. So I cut the raised tips off, and now they're perfect. It's important that you make your cables appropriately, as in know which side is which, otherwise you can accidentally mount the adapters so they either touch or the set screws aren't accessible, or both. Good buy, modification notwithstanding. ... show more
