Front Panel CONNECTIONS/STATUS LED

1.RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 150mV and 8 volts.

2.RCA Output Jacks - These pass through RCA jacks can be used to send a signal to a second amplifier. They are the summed stereo output of the one through four channel

inputs of the amplifier.

3.Status LED - Lights GREEN to indi- cate the amplifier is on and oper- ating normally and will be off if the amplifier shuts down due to short circuit, DC offset, or overheating detected by the on-board protection circuitry.

REAR PANEL CONNECTIONS

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

2.Power Fuses - These fuse(s) protect the amplifier against internal elec- trical damage and are 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.
