how many of you use compressers ?

Correct. Once you get into higher wattage PA amps, you should use speaker wire. Resonance occurs at these higher wattages that could theoretically damage a system. Newer amps of today that are 2 ohm stable are less likely to have an issue. Home consumer amps usually are not. When pushed to high wattages, they can fail because of the wire type. Because of the silver & platinum content in speaker wire, it has less resistance than regular copper wire. It is the higher resistance combined with resonance that causes the problem. It draws too many amps and overheats possibly causing damage.
