Review: Do...NOT...wire below 1 ohm. - The amp is as advertised. I have it wired too 1 ohm in a daily driver and it works flawlessly. Doesnt get real hot. No thump on turn on. And the bass knob with clip light is such a valuable tool you just cannot go wrong with the S1 series. Highly recommend. Forget the price. Forget stickers. This amplifier does its job well.
Review: Great product, True wattage, best bang for your buck. - This amp was suggested to me by a friend in the the competition side of bass. I couldnt be happier. Talk about watts for the money i give it hell and it keeps taking it. I had to do the big 3 wiring for the battery/ alternator to keep power to this baby. The clipping indicator allows you to properly adjust the amp to keep you from burning up any components unknowingly. With this you know if you are doing damage to you setup.
