Ensure ALL other cable connections are

 

 

 

 

 

 

completed before connecting this cable to the

 

 

 

 

 

 

 

 

 

 

 

 

battery. FUSION amplifiers should be connected

 

 

 

 

 

 

directly to the 12v battery terminal using the

 

 

 

 

 

 

appropriate gauge cable. Start at the vehicles

battery and run the cable through to the

EN-1502 EN-3004 EN-3001

amplifier. FUSION recommends the use of rubber

grommets when passing any cable through metal

panels to avoid sharp corners or panels that could cut through the insulation of the cable. Avoid running any cables near engine components or heater cores. An in line fuse or circuit breaker MUST be used within 30cm (12”) of your battery; this will prevent the potential risk of a fire caused by a short in your power cable (see specifications table for recommended in line fuse / circuit breaker ratings). Connect the other end of your power cable to the battery, but remember to leave the fuse out or circuit breaker off until all other cable connections are made.

2. REMOTE TURN ON

This connection turns the amplifier on and should be connected to the “Remote turn on” wire from the Head Unit. If one is not available a switched +12v source must be used, such as a power antenna wire or ACC +12v.

If you are using high level (speaker) inputs and a remote turn on wire is not available, then the “Auto Turn-On” switch must be set to audio.

3. GROUND

Connect the Ground/Earth cable for your amplifier first. Ensure that the location is a good source of ground (preferably the chassis / floor pan). Investigate the area you wish to use to ensure it is free from wiring, vacuum lines, brake and fuel lines. Use either a wire brush or sandpaper to expose bare metal, this will provide a high current contact for your ground connection. Use the same gauge cable for the ground cable as you did for the power cable. Secure the ground cable to the ground point with a bolt, star washer and nut. Apply some neutral cure silicon to the bolt and bare metal to prevent possible water leaks and rust. Connect the other end of your ground cable to the amplifier.

4A. SPEAKER OUTPUT CONNECTION Ensure the correct polarity is observed when connecting speakers/subwoofers.

2 Ohm minimum speaker impedance for stereo operation (per channel)

EN-1502

4 Ohm minimum speaker impedance for Bridged operation.
