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.

Amplifier
CEA-2006 Compliant: CEA-2006 is a system of testing and
measurement methods for mobile audio amplifiers. This voluntary standard
advocates a uniform method for determining 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 4-ohm load, with 1% or
less Total Harmonic Distortion plus noise (THD+N), and over a frequency range
(for full range amplifiers) of 20 Hz to 20,000 Hz. Signal-to-Noise ratio is
measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4
ohms. CEA-2006 standards allow consumers to compare car amplifiers and receivers
under the same conditions (apples to apples). The Kenwood KAC-1502S under
CEA-2006 regulations 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-1502S 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 output contacts ground
- speaker wire short-circuits
- unit malfunctions and DC is sent to speaker output
Power Indicator: When the amplifier is turned on the Power
indicator (on top of the amp) lights up red. This indicator turns off with the
amplifier, and will turn off if the amplifier goes into protect mode.
Gain Control: To accommodate the varying range of signal
levels from today's factory and aftermarket radios, the KAC-1502S features an
adjustable gain control; 0.2-5.0 volts (RCA).
Low Pass Crossover: The amplifier has a fixed 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
ground.
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
jacks.
Speaker Level Input: A harness is included for the speaker
level input. The input harness is common ground; it will not accept floating
ground outputs.
Fuse: The amplifier uses a 25-amp ATO blade-type fuse.
Subwoofers
Woofer: The cone is constructed of polypropylene which is
lightweight, efficient, and durable.
Surround Material: The woofer utilizes a high excursion
urethane foam for added durability and better bass performance.
Basket: The woofer features a black stamped-steel basket for
added rigidity.
Enclosure Compatibility: The KFC-W112S can be mounted in either
a sealed or ported enclosure:
- Sealed Box Volume: The recommended sealed
box sizes range from 0.8 cu/ft to 1.75 cu/ft, the ideal size being
1.25 cu/ft.
- Ported Box Volume:
The recommended ported
box sizes range from 1.0 cu/ft to 2.0 cu/ft, the ideal size
being 1.5 cu/ft using a 3" diameter x 7" long port.
