Why is my amp on but Subs not working?
Step 1: Make sure that the amplifier is properly plugged in, and the power indicator is on. Step 2: Check if all the inputs to the amplifier are correct and tightly plugged in. Moreover, inspect the RAC cables if they are connected properly. Step 3: Every amplifier has certain voltage requirements.
Why did my subs stop working all of a sudden?
Short Circuit
The most common cause of speaker failure is short-circuiting. A short circuit in the wires providing the signal will prevent the signal from ever reaching the subwoofer. A short circuit at the terminals on the subwoofer will also prevent electrical current and signal from reaching the subwoofer.
What does a blown Sub sound like?
Partial sound with distortion – When you hear a weak, distorted sound coming from your subwoofer, at any volume, you probably have a partially blown subwoofer on your hands.
Will a capacitor help my amp from cutting out?
Larger, multiple amp systems are even a bigger drain on your electrical system, in many cases depleting the system’s current capacity thereby lowering the voltage far enough that it cannot properly supply the amplifier(s). Adding capacitors can help solve this problem.
Why is my DVD saying protect?
