A Note on Power Handling
JBL Decade Series speakers are designed to produce reasonable volume levels with little amplifier power. However, the addition of a subwoofer and an amplifier will enhance the dynamic range of your system and help overcome the ambient noise in a moving vehicle. These speakers are designed to handle the power of a dedicated amplifier driven at or below its rated power. If an amplifier is driven far above its rated power, the output signal will �clip, and the additional power present � in a clipped signal can damage the speakers. Distorted or �fuzzy� sound from your speakers is an indication that the amplifier has exceeded its rated power and you should reduce the volume level.
