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

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.

Just received after my old subwoofer power amp seemed to be outputting less bass I thought I'd revitalize it with a new amp rather than repairing a 20 year old amp. Everything is included (amplifier, power supply) and all you have to do is use your own speaker cable and connect it to the subwoofer. In my case I tested the amp with my old car subwoofer and it works really well! I was initially a bit disappointed with the full max BUT that was because I had the wrong settings, thankfully the…

Wanted to find a mono amp for my old Velodyne subwoofer. I disconnected the power supply and the internal amplifier when both failed. I wanted to free up an old 220W Kenwood for my surround speakers. The subwoofer worked with a loudspeaker membrane, which was connected directly to the amplifier with wire clamps. This product arrived with no instructions and I couldn't find them on their website. I connected a subwoofer to my Denon receiver, connected this amp to the subwoofer and turned it on…
