Frequently Asked Questions - Marine M6008A INFINITY

How to install the Marine M6008A amplifier?

Choose a dry, well-ventilated location. Disconnect the negative battery terminal. Secure the amplifier using the provided screws, being careful not to puncture any lines. Perform wiring before mounting.

What to do if the amplifier does not turn on?

Check the voltage at BATT+ and REM terminals with a voltmeter. Ensure the ground connection is good. The 105A fuse must be intact.

How to adjust the amplifier gain?

Start with gain at minimum and filter at midpoint. Set source volume to 3/4. Increase gain until you hear distortion, then reduce slightly.

Which crossover mode to choose?

Use HPF for full-range speakers, LPF for a bridged subwoofer, and FULL if not using a subwoofer.

What power wire gauge is recommended?

A 4 AWG gauge is recommended for powering this amplifier.

The protection light flashes every 4 seconds, what to do?

This indicates a DC voltage output. The amplifier may need service. Refer to the warranty.

How to wire in bridged mode?

For a 4-channel bridge, connect a speaker between the positive terminal of one channel and the negative terminal of another channel. Observe polarity and minimum impedance of 4 ohms.

What settings for high level input?

Set the INPUT LEVEL switch to HI, TURN-ON MODE to DC, and INPUT MODE according to the number of channels (2CH, 4CH, or 8CH).

What to do if the sound is distorted?

Check the gain setting. Look for short circuits or grounds on the cables. If the problem persists, the source unit or amplifier may be defective.

How to maintain the Marine M6008A amplifier?

Clean with a dry cloth. Avoid exposure to water. Ensure adequate ventilation and regularly check connections.

MOUNTING THE AMP

Note: It is recommended that you make all wire connections before mounting the amplifier.

IMPORTANT: Disconnect the negative (-) battery terminal of the accessory battery before beginning the installation.

Always wear protective eyewear when using tools.
- Choose a safe mounting location. Check clearances on both sides of a planned mounting surface. Be sure that screws or wires will not puncture the vessel hull, fuel lines, or wiring harnesses, and that wire routing will not interfere with the safe boat operation. Use caution when drilling or cutting in the mounting area.
- Choose a location that provides enough air circulation.
- Do not mount the amplifier with the heat sink facing downward, as this interferes with cooling.
- Mount the amplifier so that it will not be damaged by the feet of passengers or shifting cargo.

WIRING FOR POWER AND GROUND

WIRING FOR INPUT SIGNAL

Low-level signals - 2-channel input

Note: when using 2-channel low-level signals and remote turn-on lead, set the INPUT LEVEL switch to LO, the TURN-ON MODE switch to REM, and the INPUT MODE switch to 2CH.

Low-level signals - 4-channel input

Note: when using 4-channel low-level signals and remote turn-on lead, set the INPUT LEVEL switch to LO, the TURN-ON MODE switch to REM, and the INPUT MODE switch to 4CH.

Low-level signals - 8-channel input

Note: when using 8-channel low-level signals and remote turn-on lead, set the INPUT LEVEL switch to LO, the TURN-ON MODE switch to REM, and the INPUT MODE switch to 8CH.

SETTING GAIN, CROSSOVERS, AND BASS BOOST

Setting the gain

1.Startwith GAIN control set to minimum, and the crossover control rotated midway.
2. For the front and rear channels, choose music you're familiar with. For the subwoofer channel on the Marine 6008A, choose music with substantial bass content.
3. Turn the volume control on your receiver to 14 of its total output.
4. Adjust the GAIN control clockwise, listening carefully to the bass output. If you hear distortion, turn the GAIN counterclockwise to decrease the gain.

Selecting the crossover mode

On the front and rear channels, you can select your preferred crossover mode.

Choose HPF to allow only frequencies above a certain point to reach your speakers. Recommended if you're using a subwoofer in your system, as it keeps low base from your full-range speakers.

Choose LPF to allow only frequencies below a certain point to reach your speakers. Recommended if you're bridging the front or rear channels to power a subwoofer.

Choose FULL to allow all frequencies to reach your speakers. Recommended if you're not using a subwoofer in your system.

Selecting the crossover frequency

Choose the crossover point to suit listening preferences. Turn the dials to the left to lower the crossover point and to the right to raise the crossover point. Exact crossover settings for coaxial speakers and subwoofer depend on your listening preferences.

TROUBLESHOOTING

No audio and POWER INDICATOR is off.

• No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Check voltages at amplifier terminals with VOM.

No audio and PROTECT INDICATOR flashes every 4 seconds.

DC voltage on amplifier output. Amplifier may need service; see enclosed warranty card for service information.

No audio and PROTECT and POWER INDICATORS flash.

Voltage less than 9V on BATT+ connection. Check boat charging system.

No audio and PROTECT INDICATOR is on.

• Amplifier is overheated. Make sure amplifier cooling is not blocked at mounting location. Or, there may be voltage greater than 16V (or less than 8.5V) on BATT+ connection. Check boat charging system.

Amplifier fuse keeps blowing.

• The wiring is connected incorrectly or there is a short circuit. Check wiring connections.

Distorted audio.

• Gain is not set properly. Check setting. Check wires for shorts or grounds. Amplifier or source unit may be defective.

Distorted audio and PROTECT INDICATOR flashes.

• Short circuit in speaker or wire. Remove speaker leads one at a time to locate shorted speaker or wire, and repair.

Music lacks dynamics or "punch".

• Speakers are not connected properly. Check speaker connections for proper polarity.

Engine noise—whining or clicking—in system when the engine is on.

• Amplifier is picking up alternator noise. First, check ground connection on the amplifier - a loose or improper ground is one of the main causes for noise. Turn down gain. Move RCA audio cables away from power wires. Installing an alternator noise filter on power line between battery and alternator might also be necessary.
