4PCS Heavy-Duty Car Stereo Audio Wire Reducer - 0 Gauge to 4 Gauge for Amp Input, AWG Pin Power & Ground Connection

have yet to use them but they do seem like a nice product and don’t seem like cheaply made

Works great. Even came with 2 extra set screws and the wrench. Super easy installation. Cheaper than buying at the local audio installers. Only improvement would be to include a piece of red and black heat shrink instead of 2 pieces of black.

So far so good work as should

Had to replace my car amp and had four gauge wire in my initial set up. These worked great. The amp inputs are too small for four gauge wire. These fit perfectly.

Nice, heavy duty, and clean looking installation accessory. The wire input side is large enough to fit my 0 gauge power wire.

They work great

Heavy duty well within industry standards for fitment and pricing. Heat shrink and furrles are your friends, don't forget to include them in the party.

Was very easy to work with and did exactly what their intended for
