WARNING

High-powered car audio systems may produce sound pressure levels that exceed the

threshold at which hearing loss may result.

They may also impair a driver’s ability to hear traffic sounds or emergency vehicles. Use common sense and practice safe listening habits when listening to or adjusting your audio system.

INSTALLATION GUIDELINES

1.Please read the owner’s manual carefully before you install the amplifier.

2.Disconnect the battery ground terminal prior to making any electrical connections.

3.Check for any hazards or obstructions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifiers.

4.Pick a mounting location that will provide adequate access and ventilation and protect the amplifier from heat, moisture, and dirt.

5.Avoid sharp metal areas when routing cables to the amplifier, and run RCA cables away from the power cables and other potentially noisy car harnesses.

6.The amplifier should be grounded with a short, heavy gauge wire connected directly to the car at a bare metal surface. Make sure that the metal area is part of the car chassis or frame, not a separate part with poor electrical connection to the chassis.

7.Always fuse your power connection at the battery within 8-10 inches of the battery terminal. Use a fuse or circuit breaker rated at about 5-10

more amps than the on board fuse(s) of the amplifier(s). The gauge of power wire used should take into account the total current draw of the system, and the length of wire used. IASCA and other autosound competition organizations have charts available for this; you can also find a chart in the MECP study guide. Minimum wire gauge recommendations for the individual amplifiers are listed on the specification page. It is a good idea to use the same gauge wire for the amplifier ground that you use for the power wire. Be sure to examine the battery ground cable of the vehicle and upgrade it to a gauge of wire that can accommodate the extra load created by your amplifier installation. Remember, the amplifier can only deliver its rated output when it is not current limited by the power and ground supply wires.

8.This amplifier is designed to drive a speaker load that measures from 1- 4 ohms. Keep in mind that heat is the long-term enemy of automotive electronics and that the lower your speaker load, the more heat

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

9.Your connections to the amplifier’s speaker and power terminals should be made with crimped spade lugs, and the battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts); soldering the terminals after crimping is also recommended.

10.Due to the high-frequency MOSFET switching power supply used in all Directed Audio amplifiers, 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.
