Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
CEA-2006 Compliant: CEA-2006 is a system of testing and
measurement for mobile audio amplifiers. This voluntary standard advocates a
uniform method for measuring an amplifier's RMS power output and signal-to-noise
ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts
and the RMS power output is measured into a 4Ω load, with 1% or less Total
Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to
20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted
absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards
allow consumers to compare car amplifiers and receivers under the same conditions
(apples to apples). Using CEA-2006 criteria, the Kenwood KAC-5206 is rated at 60
watts RMS x 2 channels with an 80 dBA signal to noise ratio. The signal to noise
ratio at the rated power output (not CEA-2006 conditions) is 95 dB.
2-Ohm Stable: The amplifier can support a 2-ohm load in stereo;
the 2-ohm power output is 75 watts RMS x 2 channels.
Bridgeable: This two-channel amplifier can be bridged to a
4-ohm mono load; the bridged output is 150 watts x 1 channel RMS.
Cast Aluminum Heat Sink: The KAC-5206 utilizes a cast aluminum
heat sink design to ensure the amplifier stays cool.
Protection circuitry: The amplifier features protection
circuits that will turn the amp off in case of the following events:
- speaker wire short-circuits
- speaker output contacts ground
- unit malfunctions and DC is sent
to speaker output
- the amp overheats
Power Indicator: When the amplifier is turned on the Power
indicator (on top of the amp) lights up. This indicator turns off with the
amplifier, and will turn off if the amplifier goes into protect mode.
Auto Turn-on: When using a speaker level input, the amp will
turn on automatically when it senses the input signal.
Gain: To accommodate the varying range of signal levels from
today's factory and aftermarket radios, the KAC-5206 features an adjustable gain
control; 0.2-5.0 volts line level (RCA) and 4.0-12.0 volts speaker level.
Low Pass Crossover: The amplifier has an 80Hz, -18dB/oct
low-pass filter which can be turned On or Off.
Power Connections: The power, ground, and remote turn-on
connections are 0.35" wide screw terminals. A Phillips-head or flat blade
screw driver (not supplied) is required to tighten/loosen the terminals. Spade
connectors are recommended. Minimum 10 gauge wire is required for power and
Speaker Outputs: The two pair of speaker outputs are 0.35"
wide screw terminals. A Phillips-head or flat blade screw driver (not supplied)
is required to tighten/loosen the terminals. Spade connectors are also recommended
for the speaker wires.
Note: The speaker output terminals can
be used in stereo or bridged mode.
Line Level Input: The line input is a pair of stereo RCA
Speaker Level Input: A wiring harness is included for the
speaker level input.
Fuse: The amplifier uses a 25-amp ATO blade-type fuse.
