[. . . ] · Check clearances on both sides of a planned mounting surface before drilling any holes or installing any screws. Remember that the screws can extend behind the surface. · At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas. Caution: In some cars, fuel tanks may be located directly beneath the rear deck. Check for adequate speaker-basket clearance before considering this location!· Before drilling or cutting holes, use a utility knife to remove unwanted fabric or vinyl in order to keep material from snagging in a drill bit or saw. Please read it thoroughly before proceeding. Remember to keep your sales receipt with this manual in a safe place so both are available for future reference.

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.
