However, the addition of an amplifier to drive your speakers and a subwoofer 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 any speaker. 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. General Care The loudspeaker grilles may be cleaned with a slightly damp cloth. Do not use any cleaners or solvents on the grilles or the speaker cones. 3 Declaration of Conformity We, JBL Europe A/S Kongevejen 194B DK-3460 Birkerød DENMARK declare in own responsibility, that the products described in this owner's manual are in compliance with technical standards: EN 50 081-1/1992 EN 50 082-1/3. 1995 Steen Michaelsen JBL Europe A/S Birkerød.
