    • Great for amplifiers
Used it to adapt my 1/0 gauge wires to my subwoofer amp which takes 4 gauge wires. Fit perfectly and was easy to install.

    • The product works as intended, mostly..
Nice heavy duty adapters, however.. being offset was the reason I got these, I had to modify them by using a sander and grinding flat spots in the correct location of nipple going into amp as the factory flat spots were in wrong location
