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.
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.

POWER RATINGS
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.
