Review on 🎵 Revamp Your Audio Experience with the Power Acoustik PWM-20 Four Band Parametric Equalizer by Maggie Woods

When I first installed it, I was quite happy with the device. Dead silence and good sound. Small complaints about the volume control, as others have complained, but overall a decent equalizer. So here we tinkered for about 2 hours in the garage and 15 hours on the road and it started banging the subwoofer when I hit a bump. He pulled it out and tapped the bottom center - front to back - along with the sound of the subwoofer. The side closest to the socket really hits and weakens relative to the other side. It's past the return period so I'll open it up to see if it can be fixed.
