General Installation Precautions

WARNING! Before driving the ampliﬁer mounting screws through any surface, be sure of what is behind that surface. Check for the gas tank, brake lines, and any vehicle wiring harness. Never run wires outside or under the vehicle or where they could become broken or interfere with the safe operation of the vehicle.

Before You Install

Before you install the unit, disconnect the negative (–) battery cable in the engine compartment of the vehi- cle. Doing so will prevent damage to both the electrical system of the vehicle and the ampliﬁer during installation.

Battery & Charging System

In order for the ampliﬁer to function correctly, the electrical system of the vehicle should be professional- ly checked for overall electrical capacity. When used, the ampliﬁer will increase the demand on the battery and alternator. Therefore both should be thoroughly evaluated before installing the ampliﬁer to ensure they are in normal operating condition and able to handle the increased demand the ampliﬁer will present to the vehicle’s electrical system.

Wire Routing

Do not run the power wire near any low-level signals or audio cables such as the RCAs from the head unit. (Noise can be introduced into the ampliﬁer when this occurs.) It is helpful to diagram the wire layout ﬁrst before any installation is attempted.
