REAR PANEL CONNECTIONS

1.Sub Out Terminals - Connect the speakers to these terminals. (Refer to the Speaker Connection section of this guide.)

2.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.

3.(+) 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.

4.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. If a (+) 12 volt remote turn lead is not avail- able, a Remote Power Adapter (P/N #55000) can be used to supply a remote turn on signal. DO NOT connect this terminal to constant (+) 12 volt.

5.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 wire. DO NOT connect this terminal directly to the vehicle battery ground terminal or any other factory ground points.
