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.

WIRE CONNECTOR PLUGS

Power and speaker wire connections on Viper Audio power amplifiers are performed with the use of specially designed connectors that allow for ease of wire termination and installation convenience.

Poor connections are a common cause of poor sound quality or amplifier perfor- mance. Making proper wire connections is paramount to a reliable, quality sound system.

2.Cut wires to the minimum length necessary.

3.Trim the wire ends so bare wire does not protrude from the connector after termination.

4.Always tighten the connector screws firmly at least twice, once during installation and once more before returning the car to the customer.

Please follow these recommendations to

CAUTION: Over tightening the screws can cause them to
