Hello all.. I'm having a problem with an amp that my brother has had for quite a few years... he only used it for about a year and never abused it. Then one day it just stopped working.. All it does is moves sub back and forth at a slow rate even when not hooked to rca jacks. When it does this it draws a lot of power from the power source and the red led light on the board stays lite the whole time and blinks with the draw of power. All wiring is hooked up right. I was wondering if someone had this problem before and how it fix it. Its a Power Acoustik Fire & Ice FI2X-1600 amp.
