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

The protection circuitry will operate instantaneously, turning off the arnplifier.

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

away from the signal cords (RCA cords) and speaker feads. Also, keep the power leads away from any antenna cords. Amplifier ground leads (black) should be connected to a solid metal part of the vehicle body. #f using mukiple amplifiers, connect al! amplifier ground jeads to the same point to prevent noise problerns. To get good contact when grounding, you may have to sand away the paint to expose ihe metal underneath. To operate the amplifier and car stereo properly, connect the

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

For detailed information on connections between different units and the amplifier, see the owner's manuals for the units, and follow their recommendations precisely.

Connecting the battery lead (red) Route the battery lead (red) from the engine compartment to the passenger compartment to connect it to the amplifier. To prevent a short circuit, do not connect the positive (+) lead of the battery until the other jeads have been connected.

Installation

14

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.

the amplifier is installed in the passenger campartment, fix it securely, otherwise it may break free while the car is moving, and cause an injury or an accident. 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 rernoved, then reconnect the lead to the negative battery terminal. Before drilling any mounting holes, check behind where you want to make the hole to make sure you do not drill into anything, such as 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 leads 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 wil impede air circulation, causing the amplifier to overheat and possibly fail.

Do not install the araplifier near the heater outiet, otherwise it may overheat andi fail.

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 anyplifier. Consult your dealer before making any holes in the car.

Care and Maintenance Specifications i

* When replacing the fuse, replace it with one with the correct rating. Ifthe 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,

* The protection circuitry will operate instantaneously if a mafl- function occurs, turning off the amplifier. ff this happens, dis- connect the power to the car stereo system, check the wiring for the cause of the problem, and, if found, correct it before using the stereo system again.

e Do not turn the volume up so high that you cannot hear police car, ambulance, or fire engine sirens.

| li the amplifier will not operate properly, contact your dealer or | nearest authorized Pioneer service station.
