compromised. Our authorized dealer has been trained to maximize your system’s sound quality when
Ω speaker loads when used in Stereo Mode. When
a channel-pair is bridged, the recommended
minimum load impedance is 3Ω for subwoofer use,
and 4Ω for full range operation. Although
operation with lower impedances is not likely to
cause immediate damage to the internal circuitry,
the unit will most likely overheat, causing the
thermal protection circuitry to shut down the
operation will resume.
conditions is not recommended and will reduce its
life expectancy. Most speakers designed for car
audio operation are 4Ω impedance. Connecting
two such speakers in parallel will result in a 2Ω
nominal impedance, which is not recommended
Poor bass response Speakers wired wrong
polarity causing cancellation
at low frequencies
Check speaker polarity and repair as
needed
Crossover set incorrectly Reset crossover referring to the
section of this manual for detailed
instructions
Battery fuse blowing
too low
Check speaker impedance load. If below
2Ω stereo or 4Ω mono, rewire speakers
to achieve a higher impedance
Short in power wire or
incorrect power connections
Check power and ground connections
and repair as needed
Fuse used is smaller and
recommended
Replace with proper fuse size
Too much current being drawn Check speaker impedance load. If below
2Ω stereo or 4Ω mono, rewire speakers
to achieve a higher impedance and
replace with recommended fuse size
Short in power wire or incorrect
wire
Check power and ground connection and
