Question about American Pro VS-2043 Car Audio Amplifier
ALL MY SPEAKER WENT QUIET AND NOW I CANT GET MY SPEAKER WORKING SWITH THE AMP ON AND THE RED LIGHT STAYS ON AND IT WONT GO BACK TO GREEN HELP
Check your speaker connections and the try to power the unit on again. I fear that you may have damaged the power amplifier MOSFETs on the output stage. This is what this sounds like. I would first try to see if audio is going into the unit by using an oscilloscope and taking a reading at the input of the amplifier. If audio is preset I would take the unit to a shop since there are no user serviceable parts inside of this device. Look for a shop that will give you a free estimate. I do feel that you have internal damage to that device.
