TYPICAL INSTALLATION SEQUENCE

The following represents the sequence for a typical amplifier installation, using an aftermarket source unit or OEM Interface processor (like the CleanSweep® CL441dsp). Additional steps and different procedures may be required in some applications. If you have

connection and secure the disconnected cable to prevent accidental re-connection during installation. This step is not optional!

2)Run power wire (minimum 4 AWG) from the battery location to the amplifier mounting location, taking care to route it in such a way that it will not be damaged and will not interfere with vehicle operation. Use 2 AWG or 1/0 AWG power wire if additional amplifiers are being installed with the 1000/1v2.

3)Connect power wire to the positive battery post. Fuse the wire with an appropriate fuse block (and connectors) within 18 inches

(45 cm) wire length of the positive battery post. This fuse is essential to protect the

4)Run signal cables (RCA cables) and remote turn-on wire from the source unit to the amplifier mounting location.

5)Run speaker wire from the speaker systems to the amplifier mounting location.

6)Find a good, solid metal grounding point close to the amplifier and connect the negative power wire to it using appropriate hardware. Use minimum 4 AWG power wire, no longer than 36 inches (90 cm) from the amplifier to the ground connection point. In some vehicles, it may be necessary to upgrade the battery ground wire. (See page 5 for important notice).

7)Securely mount the amplifier using appropriate hardware.

8)Connect the positive and negative power wires to the amplifier. A fuse near the amplifier is not necessary.

9)Connect the remote turn-on wire to the amplifier.

10)Connect the RCA input cables to the amplifier.

11)Connect the speaker wires to the amplifier.

12)Carefully review the amplifier’s control settings to make sure that they are set according to the needs of the system.

13)Install power wire fuse (100A for a

single 1000/1v2) and reconnect the negative battery post terminal.

14)Turn on the source unit at a low level to double-check that the amplifier is configured correctly. Resist the temptation to crank it up until you have verified the control settings.

15)Make necessary adjustments to the input sensitivity controls to obtain the right overall output and the desired balance in the system. See Appendix A (page 14) for the recommended input sensitivity setting method.

16)Enjoy the fruits of your labor with your favorite music.
