REAR PANEL CONNECTIONS

1.Power Fuse - This fuse protects the amplifier against internal electrical damage and is meant to protect the amplifier only. All other power connections should be fused at the source. The A502 uses 1-30A fuse, and the A404 uses 1-30A fuse.

2.(+) 12 Volt Power - Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery.

WARNING: Always protect this power wire by installing a fuse or circuit breaker of the appropriate size within 12 inches of the battery terminal connection.

3.Remote Turn On - This terminal turns on the amplifier when (+) 12 volt is applied to it. Connect it to the remote turn on lead of the head unit or signal source.

4.Ground - Connect this terminal directly to the sheet metal chassis of the vehicle using the shortest wire necessary to make this connection. Always use wire of the same gauge or larger than the (+) 12 volt power wire. The chassis connection point should be scraped free of paint and dirt. Use only quality crimped and/or soldered connectors at both ends of this
