speaker load, the more heat is generated. For low impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable.

9.Battery and ground connections to the vehicle should be made with crimped ring terminals of the appro- priate size (surface area is what counts); soldering the terminals after crimping is also recom- mended.

10.Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can’t deliver full output if the power supply is restricted). Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system.

1.RCA Output Jacks - These pass through RCA jacks can be used to send a signal to a second amplifier.

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

3.Status LED - Will light GREEN to indicate the amplifier is on and operating normally and will be off if the amplifier shuts down due to short circuit, DC offset, or over- heating detected by the on-board protection circuitry.
