Never connect a speaker lead to ground or to other speaker grounds.

The protection circuitry will operate instantaneousty, turning off the amplifier.

To prevent noise problems, keep the power leads to the amplifier

away from the signal cords (RCA cords) and speaker leads. Also, keep the power leads away from any antenna cords. Amplifier ground | 5 (black) should be connected to a solid

metal part of the vehicle body. if using multiple amplifiers, connect all amplifier ground leads to the same point 19 prevent noise problerns. To get good contact when grounding, you may have to sand

battery lead and the accessory power lead (red) correctly, If the leads are not connected correctly or are not connected at all, the amplifier and car stereo will not work.

Installation

2 Install the amplifier where it will not get in the way of driving, and will not be a danger to passengers during an emergency stop:

e ifthe amplifier is instailed in the passenger compartment, fix it securely, otherwise it may break free while the car is moving, and cause an injury or an accident

e Do not install the amplifier anywhere that can get wet, otherwise it may give an electric shock if touched.

© To prevent a short circuit, disconnect the negative battery lead before beginning installation. After installation has been completed and checked, reinstall any components that were moved or removed, then reconnect the lead to the negative battery terminal.

¢ Before drilling any mounting holes, check behind where you want 1o make the hole to make sure you do not drill into anything, such

the gas line, brake lines, electrical wiring, ete. If installed under a front seat, make sure the amplifier does not obstruct seat movement. Route ali ileads and cords carefully so the sliding seat mechanism does not pinch them and cause a short circuit,

* Do not install the amplifier under the carpet or a floor mat, as this will impede air circulation, causing the amplifier to overheat and possibly fail

¢ Do not install the arnplifier near the heater outiet, otherwise it may overheat and fail

e Use only the parts supplied, and install the amplifier securely. If parts other than those supplied (specified) are used, they may come loose or cause damage to internal parts of the amplifier.

e Gonsull your dealer before making any holes in the car.

» If mounting the amplifier vertically, buy some 5-mrm-diameter

screws and nuts, and use them to secure the amplifier firmly, so that it cannot be dislodged by the vibration of the car.

+ There are 4-mm-diameter screw holes on the right and left at the rear of the amplifier, These are used to fit an optional amplifier installation end cap. Do not use them for anything else

When replacing the fuse, replace it with one with the correct rating. If the correct fuse is not used, the amplifier may be damaged ar there may be a fire. Do not use the amplifier at high volume for a long time with the engine stopped or idling. It may make the battery go flat, making it difficult to start your engine.
