Frequently Asked Questions - EN-AM10005 Fusion

Why is my amplifier not turning on?

Check that the +12V power wire has a good connection to the battery and the inline fuse is intact. Also verify that the remote turn-on wire (REM) receives +12V from the head unit or a switched source.

What should I do if the amplifier is on but there is no sound?

First, check the RCA connections from the head unit. Ensure the gain control is set correctly (turn head unit to 3/4 volume, then adjust gain until desired level). Also verify speaker wires are not shorted and speakers are functional.

How can I prevent my amplifier from overheating?

Install the amplifier in a well-ventilated area with at least 2.5 inches of clearance around it. Never mount it upside down. If space is tight, use a small fan to aid heat dissipation. Avoid mounting on subwoofer enclosures due to vibration.

Can I bridge the channels for more power?

Yes, the front and rear channels can be bridged. For the EN-AM10005, bridged output is 200W RMS x 2 @ 4 ohms while maintaining 170W x 1 for the subwoofer channel. Ensure minimum impedance of 4 ohms when bridged.

What is the correct way to set the gain (level) control?

Turn the amplifier's level control to minimum. Set the head unit volume to about 3/4 of maximum with bass and treble at zero. Slowly increase the amplifier level until the volume is satisfactory but before distortion occurs. The gain is not a volume control; improper setting can damage speakers.

How do I connect a subwoofer to this 5-channel amplifier?

Connect the subwoofer to the 'SUB' speaker output terminals. Use the dedicated subwoofer RCA input (channel 5). Set the subwoofer crossover switch to LP (low-pass) and adjust the frequency to 100 Hz or below. Ensure the subwoofer impedance is 4 ohms or higher for stable operation.

What fuse size does the EN-AM10005 require?

The amplifier uses three 25A fuses. Always replace with the same type and rating. Using a different fuse can cause damage or fire hazard.

Why does the protection LED turn red?

The red LED indicates a fault: short circuit, overcurrent, or thermal overload. Check speaker wires for shorts, ensure the amplifier is not overheating, and verify that the impedance load is not too low (minimum 2 ohms stereo, 4 ohms bridged).

Can I use the amplifier with a stock head unit?

Yes, if the stock head unit has low-level RCA outputs. If not, you may need a line output converter (LOC) to adapt speaker-level signals to RCA. The amplifier's input sensitivity (0.2-8V) accommodates most head units.

How should I ground the amplifier?

Connect the ground terminal (GND) to a clean, unpainted metal area of the vehicle chassis (e.g., floor pan) using the same gauge wire as the power cable (minimum 8 gauge). Scrape away paint to ensure good contact and seal with silicone to prevent rust.

INSTALLATION

Before any wiring and installation is performed, FUSION recommends you first plan the complete installation. Look at wiring routing, amplifier location and fitment. Please re-check the installation at completion.

Appropriate mounting is very important for prolonged life expectancy of any amplifier. Select a location that allows enough space so sufficient airflow is maintainable and a location that provides protection from moisture. Keep in mind that an amplifier should never be mounted upside down. Upside down mounting will compromise heat dissipation through the heatsink and could engage the thermal protection circuit.

Excessive heat will shorten your amplifiers life. To maximise heat dissipation, be sure to leave at least 2.5 inches of clearance around the amplifier. If space is of the essence and the amplifier must be mounted in an enclosed or restricted area, a small 3 inch fan should be used in correspondence with a duct so the heat can flow past the heatsink.

WARNING: Do not mount any amplifier on a subwoofer enclosure as extended exposure to vibration may cause malfunction of the amplifier.

To avoid scratching your new FUSION Amplifier, pre-drill the mounting holes with either a 3mm or 9/64" diameter drill bit and use the screws supplied in the accessory kit.

INSTALLATION WARNING

1: Ensure the vehicle 12 volt lead is removed from the battery before any equipment is connected
2: Investigate the vehicles gas tanks, brake lines and electrical wiring locations before you begin installation
3: Attach the product securely to the vehicle to prevent damage in the event of an accident
4: Ensure all wiring is protected to avoid damage or pinching of the cables

WIRING

Make sure before any connection is made to the amplifier or source unit, ensure that you turn the audio system off. Failure to do so could result in either the stock system or your new FUSION product being damaged. FUSION will not warranty damaged amplifiers due to incorrect installation.

When wiring the FUSION amplifiers, ensure that the wires are away from sharp objects and that rubber grommets and insulated bungs are used when wiring through door jams and any other steel panels. FUSION recommends using 8 gauge power and ground wire for power installation. Please see power cable calculator (Fig.1).

Ensure that when connecting the wires to the speakers and audio system, the terminals and connections are protected from the vehicle chassis and shorting to each other. If the wires short

CONNECTION

Note: Ensure the audio system is off during the installation of FUSION product. Once the installation is complete FUSION recommends that you turn the volume of the source unit up slowly so not to damage the speakers. Please recheck the complete installation prior to turning the audio system on.

FUSION amplifiers should be wired directly to the vehicle battery using the appropriate sized cable. Start at the vehicle battery and run the power cable through to the amplifier. FUSION recommends the use of grommets when passing the power cable through any metal wall, and to avoid sharp corners or sharp body parts that may easily cut through the insulation on the cable.

Avoid running the power cable over engine components or near heater cores. The use of an inline fuse or circuit breaker is essential. This will prevent the risk of a potential fire caused by a short circuit in your power cable. Connect the fuse holder or circuit breaker as close to the battery positive terminal as possible. Use a fuse or circuit breaker of equal value as that found on the chassis of your FUSION amplifier. You may now connect the cable to the battery, but remember to leave the fuse out or circuit breaker off until all other cable connections are made.

GROUND

When grounding your FUSION Amplifier locate a metal area close to the amplifier that is a good source of ground (preferably the floor pan). Once again, investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Use either a wire brush or sandpaper to eliminate unwanted paint. This will allow a better contact for your ground. Use the same gauge cable for the ground as you did for the power. Secure the ground cable to the body using a bolt, star washer and nut. Spread silicon over the screw and bare metal to prevent rust and possible water leaks. Now it's time to connect the power and ground cables to the amplifier. Cut both cables to length. Use a #2 Phillips type screwdriver to loosen the +12V and the GND connections on the amplifier. Terminate the ground first, and then the +12V. Make sure that you terminate them into the correct terminals, now tighten the screws down securely.

REMOTE TURN-ON

This terminal must be connected to a switched +12V source. Typically, remote turn-on leads are provided at the headunit which will turn on and off the amplifier in correspondence with the source. If the head unit does not have a remote turn-on lead, then a power antenna wire can be used. If neither of these leads are present on the head unit then a switched +12V supply must be used, like the ACC +12V.

Run a minimum of 18 gauge wire from the amplifier location to the source of the switched +12V lead. If possible, route this wire on the same side of the vehicle as your power cable. Connect the source remote output to the wire. Go back to the amplifier and cut the wire to length. Loosen the screw terminal marked REM on the amplifier using a #2 Phillips type screwdriver. Slip the wire into the connector and tighten the screw securely.

Keep in mind, FUSION Encounter series are high power amplifiers and not high current amplifiers. In other words they require a minimum impedance of 2 ohms STEREO and 4 ohms bridged MONO to operate trouble free. Too low an impedance could send your FUSION amplifier into protection mode and/or damage the amplifier.

SPEAKER WIRING

Choose the correct speaker wire for your application. Most applications will require a minimum of 16 gauge. Route the speaker wire using the same precautions you did when you ran the power cables. Terminate these wires at the speaker end using insulated speaker terminals (not supplied) or by soldering the connection. Make sure the speaker connections are positive to positive and negative to negative. At the amplifier end, use a #2 Phillips screwdriver to loosen the speaker terminals on the amplifier. Connect the speaker wires and tighten the screws securely. Check to make sure you've maintained proper polarity and balance.

RCA INPUT CONNECTION

LOW LEVEL INPUTS

Choose the correct length and style of RCA interconnects for your needs. The FUSION range of RCA's gives you a wide choice to suit your needs. These have multiple layers of shielding or are a twisted pair variety for better noise rejection (consult your FUSION dealer if unsure which to purchase).

Be extra careful with your RCA interconnects. Car environments are notorious for poorly insulated wires. This means that hiss, engine noise, and fan noise can easily be picked up through RCA cables if run incorrectly. Avoid running your RCA's near large wire looms and electric fans if possible. Run your RCA cables on the opposite side of the vehicle to the power cable. Be sure to check for correct balance. (Red is right and black or white is left).

LEVEL CONTROL

The LEVEL control on the amplifier allows you to match the input level of the amplifier to the output level of your head unit. Matching the input can be accomplished in three simple steps:

1: Turn the LEVEL control on the amplifier to minimum.
2: Turn up the headunit and adjust to 3/4 maximum volume ensuring that the BASS and TREBLE are set to zero.
3: Adjust the LEVEL control until desired volume is achieved without audible distortion. Remember, the gain control is not a volume control. Ignoring the three steps above may leave you with damaged speakers and/or a damaged amplifier.

13 FRONT RCA INPUT:

Connect these RCA connectors to the front low level output connection from the headunit.

14 GROUND INPUT:

Connect directly to the vehicle's chassis via an 8 gauge power cable. Note: This is the first wire to connect when wiring up a amplifiers, damage could result if this is not done.

15 REMOTE INPUT:

This terminal is for turning the amplifier on and off. The remote input requires a switched positive (+12V) to power 'ON' the amplifier, this can be found on the rear of the head unit in the form of a electric antenna output, or a remote on output. If not available you can wire to the ACC position on the key.

16 +12V INPUT:

Connect directly to the vehicle battery positive (+) terminal via an 8 gauge power cable, with an inline fuse or circuit breaker at the battery end. Note: This is the last wire to connect up during installation, damage could result if this is not done.

17 FUSES:

Please ensure the correct type of fuse is fitted, as specified in this manual. Note: the EN-AM10005 has 3 x 25A fuse.

18 SPEAKER OUTPUT:

See 5/3 channel installation diagrams on page 33 for correct speaker connection.

OHMS LAW SIMPLIFIED

SERIES AND PARALLEL SUBWOOFER WIRING FOR DUAL VOICE COIL SUBS

Parallel Voice Coil Wiring

To wire a DVC subwoofer in parallel in order to get 2 Ohms, use two short pieces of speaker wire and link the positive from one coil to the positive of the second coil and do the same for the negative as shown in fig 1. Then wire the amplifier to opposite sides of the subwoofer in order to equalise any connection resistance.

Series Voice Coil Wiring

To wire a DVC subwoofer in series in order to get 8 Ohms, use one short piece of speaker wire and link the positive from one voice coil to the negative of the second coil as shown in fig 2. Then wire the amplifier to opposite sides of the subwoofer.

PARALLEL WIRING FORMULA FOR 2 SPEAKERS

R 1 × R 2/R 1 + R 2 = LOAD IMPEDANCE

4 Ohms × 8 Ohms/4 Ohms + 8 Ohms = 3 2/1 2 2. 6 7 Ohms

SERIES WIRING FORMULA FOR 2 SPEAKERS

R 1 + R 2 = LOAD IMPEDANCE

TROUBLE SHOOTING

Before you contact your FUSION dealer or service centre FUSION requires that you do some simple trouble shooting to help to diagnose the problem.

If the FUSION Amplifier has been installed by a professional installation company, then we recommend that you return to the company so that the technician can assess the problem and advise.

Problem Possible reason Solution

Amplifier not switching on. Power LED not ‘on’	No +12v to power wire	Check fuses and connections to battery
	No power to remote wire	Check remote on connections to head unit
	Fuse broken Replace fuse with correct type and amperage
Amplifier not working, but status LED ‘on’	Fuse on amplifier blown	Replace fuse with correct type and amperage
	Amplifier too hot Move amplifier to vented areaTurn head unit down
	Speaker wires shorted	Check that there are no speaker wires shorted to another wire or to the vehicle chassis
No sound	RCA Signal Check RCA connection to head unit
	Gain control not set up	Ensure you have set up the amplifier gain level control
	Head Unit Check head unit volume level
	Amplifier Check all power, remote on and ground connections
	Speakers Check speakers for wire shorts
