Underpower Vs. Overpower

1

Most speaker damage is caused by amplifiers with too little
power (wattage).

2

An overdriven amplifier clips the waveforms and leads to
speaker distortion.

3

Clipping is usually audible and it may vary from a harsh sound
to a fuzzy or unclear sound.

4

If you hear the clipping at high volume levels, turn down the
volume until the distortion is gone.

5

Damage caused by operating the speakers at distorted volume
levels is not covered by the warranty.

red and on the other one black. Connect to the red side of the
amplifier and speakers (+) tab. Connect one end of the black side
(-) in the other tab. Connect each speaker to make sure that is
not (+,-) inverted polarity. If the polarity of the speakers is
reversed, the sound will be unnatural and will play without bass.
