Review: Good product - Exelance in heavy bass
Review: Best Low pass filter For such a low price. - This is the best low pass filter for such a low price. It works on 12+ 0 12- supply can also work on 24+ 0 24- supply! It can be the best low pass filter if u know how to use it properly without overdriving it. It doesn't heat up also it has no power led so yea u will not understand if the low pass filter is powered on. Also the solder pads are kind of small so solder the wires properly without shorting, if u don't connect Gnd near the audio input area properly, hiss of humming sound can occur. LOVE THIS PRODUCT , GOOD ENOUGH TO MOVE A 12INCH SUB👍🏻👍🏻
