Review: Works well and easy you install - Just installed my 11' Boss sub with 1100w. I think some of these comments are user problems. I've had it for a while and it's does it's job just fine.
Review: Flawless - Probably works OK on Boss amplifiers, but as such, it didn't do it for my old Bass600 Subwoofer. But hey, it's just a *potentiometer*, so I just re-wired the included cable: pin 6 --> pin 1 and pin 5 --> pin 2. Voilà! Good product.
