Hifonics VULCAN VX690A User Instructions

POWER RATING

The HiFONICS VULCAN VX subwoofer enclosures are

designed for high bass levels. Anyhow it is possible, that

unsatisfying sound characteristics could be caused by too

low or too high amplifier power. In certain circumstances

this even can cause a damage to the loudspeakers.

It is recommended to choose rather a more powerful am-

plifier (ca. 15-20% more Watts RMS than the max. RMS

power rating of the woofer) and to use the amplifier not

at the maximum output level (low distortion factor, good

sound characteristics). A weaker amplifier at the maximum

level causes worse sound characteristics due to the high-

er distortion factor.

Never crank up the output volume of your amplifier to the

maximum level or run the amplifier into the clipping range.

If the sound is distorted and not clean, turn back the level

until the distortions disappear.

Please note the following recommended power ratings:

VX690R: One Amplifier with approx. 160 to 250 Watts

RMS @ 4 Ohms.

The HiFONICS VULCAN VX subwoofer enclosures have

no integrated limiter or clipper, which is limiting the level

upwards. Overamplified bass peaks leads inevitably to a

burn out of the voice coil of the woofer. A burn out of the

voice coil, caused by clipping/overamping is not covered

by the usual warranty

IMPORTANT NOTES

Choose a suitable location for your soundsystem, that

neither the driver's field of vision nor the security of the

inmates will be affected. This stands also for airbag-zo-

nes and safety belts. The permanent temperature of the

location should not be lower than 5°C and not higher than

50°C. Protect the device from moisture and humidity.

Ensure that your subwoofer enclosure will not get loose

during the drive and hurt someone in the passenger cabin.

It is recommended, that you mount the subwoofer enclo-

sure with suitable belts or any other mounting solutions in

the trunk area.

Please ensure not to damage any serial components of

your vehicle (airbags, wires, gastank etc.) during the ins-

tallation of your soundsystem by drilling or any other ope-

rations.

USER INSTRUCTIONS

Never screw or mount any other devices (amps, caps etc.)

onto the subwoofer enclosure, this may cause damage to

the electricity.

For your personal concerns you should choose a approp-

riate sound level for the subwoofer enclosure, that neither

the roadworthy of the driver nor his concentration will be

disturbed, that he is able to notice possible traffic noises

and acoustical warning signals.

Modern car audio soundsystems provide very high acou-

stic pressure beyond the 100 dB mark. Please observe in

this case, that permanent use of high sound levels may

cause damage to your ability of hearing.

Please ensure by any means the correct polarity of all con-

nections. Faulty installed and connected devices may get

damage the vehicle and the device permanently.

Please check in any case the operation guide or wiring

manual of your amplifier which you'd like to use for the

soundsystem.

Never connect the speaker terminals with the 12 Volt pow-

er supply, otherwise the speakers may get damaged.
