Insert a CD of 50Hz or 1kHz at 0dB into the source unit, set the multimeter to AC voltage ranging between 10 – 100VAC, and place your multimeter probes on the amplifier output terminals. A good amplifier is expected to produce a voltage reading that is ideal for the recommended wattage output.

How can you tell if an amp is blown?

How do you diagnose an amplifier? Test the sound by unplugging the sound cables or colored RCA wires. Hissing and crackling are often easy to fix by rearranging the wires or getting complimentary speakers. If the noise doesn’t stop, then you probably have a faulty amp to replace.

  2. If the noise doesn’t stop, then you probably have a faulty amp to replace.

Can an amp be too weak for speakers?

If you don’t have a powerful enough amplifier to reach the volume levels you want, you can damage the speakers by feeding them too much high-frequency energy by driving the amplifier into clipping. It’s the extra power in these harmonics that damages speakers.
