What is a 8 ohm load, 4 ohm load?
 This is the resistance (impedance) presented by the speakers that is seen by the amplifier. This can also include any crossovers and circuits connected to the speakers. When the load decreases, the amplifier’s output increases. There is less resistance to the current, and the speakers can draw more power from the amp. Drawing more power than the amplifier was designed for will damage the amp. Every amplifier is designed to handle a certain load. For home amplifiers this number usually starts with 8 ohms. With car amplifiers it is usually 4 ohms. All amplifiers can handle a higher resistance (load), but they will produce less output. Most quality amplifiers can also handle a lower resistance. Most car amps can handle a 2 ohm load, while some can go as low as 1/2 ohms.
