Review on 🔊 Douk Audio G4 Subwoofer Monoblock Power Amplifier with 100W Full-Frequency Digital Output by Sopheak Kupke

I have an old Kenwood 10 inch subwoofer. The speaker failed a few years ago. This amp drilled a hole in the back of a Kenwood subwoofer, plugged in a kicker, filled the hole with silicone around the wires and it works amazing! Louder than original. In fact, you need to use a power level of around 40%. This is in my home gym, about 600 square feet, and it sounds fantastic. I'll get another one as soon as my upstairs amp fails.
