LED-ILLUMINATION

The HiFONICS MERCURY MR subwoofer enclosures have an integrated LED-illumination. This

illumination is only allowed to light up, if the vehicle is not in driving condition. It is recommended to

switch the illumination with the vehicle's trunk illumination.

Right Terminal:

The HiFONICS MERCURY MR 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 amplifier (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 higher 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.

The HiFONICS MERCURY MR 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.

Recommended power ratings:

• 1 x stereo-amplifier (one channel per terminal) with 2 x 250 - 350 Watt RMS (Sinus) into 4 Ohms

• 1 x mono-amplifier (parallel-operation on both terminals) with 500 - 700 Watts RMS into 2 Ohms

• 1 x bridged stereo-amplifier (parallel-operation on both terminals) with 500 - 700 Watts

RMS into 2 Ohms. IMPORTANT: the amplifier must be stereo (per Channel) 1 ohm stable

Please refer to the minimum impedance of the installed amplifier. In case of doubt ask your speci-

alist dealer.

Please also refer to the interconnection examples on the next page.

Switch for illumination (bluw / white)

For the + 12V power supply of LED-illumination, use

the attached cable at the right terminal and connect

it accordingly. Please ensure the correct polarity as

marked.

NOTE: Do not use the speaker cables as power supply

for the LED-illumination.
