Recommended Power For One Subwoofer
Blue (Minimum):
If you are powering your sub in this
range, it will operate comfortably with
zero strain or fatigue. Power ranges
this low will not damage your
speaker, but it wont capture the
Subzero full capabilities.
Yellow (Optimized):
This zone represents the best
compromise between long-term
reliability, high-output and low-
distortion. If you are operating your
subwoofer in this range you are
taking advantage of the best low
distortion and sound quality that the
Subzero is capable of delivering
between the recommended power.
Red (Maximum):
In this zone low-distortion and sound
quality become compromised. A
small amount of SPL can be gained
in this zone, but only a couple of dB.
Remember that the more you travel
out of the recommended power
range the greater the chances of
failure and warranty rejection. Be
wise and use extreme caution and
care with your speakers.
Black (DON’T):
In this zone the chances of failure are
almost inevitable. When exposed to
excessive heat and/ or mechanical
stress the driver will loose sound
quality, SPL and could seriously
damage the driver or you vehicle.
