mounting and installation 25 f uses wiring tips When making electrical connections to your amplifier , please observe the following: Use at least 8 gauge wire for power and ground connections. Wire the amplifier directly to the car battery . For the ground connection, use the shortest possible wire to a good chassis ground point.
The built-in protection circuitry in the Pyramid Crystal amplifiers will disable the amplifier if it senses an input overload, a speaker short circuit, or extreme temperature conditions. When the protection circuit is activated by any of these conditions, the Protection LED will be illuminated.
Do not operate the amplifier when it is unmounted. Attach all audio system components securely within the automobile to prevent damage, especially in an accident. Do not mount this amplifier so that the wire connections are unprotected, or in a pinched condition, or likely to be damaged by nearby objects.
