INST

ALLATION

5. Strip 1/2" from the battery end of the power cable and crimp a large ring terminal to the cable. Use the

ring terminal to connect to the battery positive terminal.

6. Prepare the BLACK wire (Ground cable) by stripping 1/2" of insulation from the end of the wire. Insert the

bared wire into the “-” terminal on the plug connector. Tighten the set screw with a 3/32" allen wrench

to secure the cable in place. Prepare the vehicle chassis ground by scraping any paint from the metal

surface and thoroughly clean the area of all dirt and grease. Strip the other end of the wire and attach a

ring connector. Fasten the cable to the chassis using a non-anodized screw and a star washer.

NOTE: Keep the length of the BLACK wire (Ground) as short as possible. Always less than 30"(76.2cm).

Power

Connection

7. Prepare the Remote turn-on wire by stripping 1/2" of insulation from the end of the wire. Insert the

bared wire into the “R” terminal on the plug connector. Tighten the set screw with a 3/16" allen wrench

to secure the cable in place. Connect the other end of the Remote wire to a switched 12 volt positive

source. The switched voltage is usually taken from the source unit's accessory lead. If the source unit

does not have this output available, the recommended solution is to wire a mechanical switch in line

with a 12 volt source to activate the amplifier manually.

8. Securely mount the amplifier to the vehicle or amp rack. Be careful not to mount the amplifier on

cardboard or plastic panels. Doing so may enable the screws to pull out from the panel due to road

vibration or sudden vehicle stops.

9. Connect source signal by plugging the RCA cables into the input jacks at the amplifier.

CAUTION: Always ensure power is off or disconnected at the amplifier before connecting

RCA cables. Failure to do so may cause injury, damage to the amplifier and/or

connected components.

10. Connect the speakers. Strip the speaker wires 1/2" and insert into the speaker plug connector and tighten

the set screw to secure into place. Be sure to maintain proper speaker polarity. DO NOT chassis ground

any of the speaker leads as unstable operation may result.

11. Perform a final check of the completed system wiring to ensure that all connections are accurate. Check

all power and ground connections for frayed wires and loose connections which could cause problems.

12. Ensure the amplifier is mounted securely and reinstall the end cover. Install an inline fuse near the

battery connection.

NOTE: Follow the diagrams for proper signal polarity.

CAUTION: These amplifiers are not recommended for impedance loads below 2 .

CAUTION: Do not attempt to connect the source units speaker leads directly to the RCA

connections of this amplifier, as damage to the source unit and/or the

amplifier may result.
