How can I safely connect a 16 ohm amp to an 8 ohm speaker without causing damage to either component?

To safely connect a 16 ohm amp to an 8 ohm speaker without causing damage, you can use a series resistor to match the impedance. This resistor should have a value of 8 ohms to create a total impedance of 16 ohms when connected in series with the 8 ohm speaker. This will ensure that both the amp and the speaker are protected from damage.
