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.

Features
Line Level Inputs:
The RCA type line-level inputs have a gain (Input
Sensitivity) control. The
Input Sensitivity control will accept an input signal of 200mV to 5.0 Volts.
Speaker Level Input: The
KAC-7202 comes with a speaker level input harness. Once you splice
the speaker wires from the receiver to the harness, you have
plug-in convenience to the amplifier. This feature makes it easier to add an
amplifier to a factory radio or to a receiver with no preamp outputs. The maximum
power output from the source receiver can be no more than 40 watts.
Line Level Output:
The amplifier has a line level output for feeding a second
amplifier. The output is the same signal fed to the input.
Crossovers: The
KAC-7202 has built-in high pass and low pass crossovers. The high pass
crossover's slope is 12 dB/octave and is
continuously variable from 50Hz to 200Hz.
The low pass crossover's slope is 24 dB/octave and is also continuously variable from 50Hz to 200Hz.
Bass Boost:
The bass boost is adjustable from 0-18dB at 40Hz.
Fan:
There is a fan on top of the amp to help dissipate heat and ensure cool,
reliable operation.
Stereo/Mono Operation:
If the KAC-7202 is to be bridged, the operation
mode switch on the top of the amp is set to mono.
When switched to Mono, the signal from the left channel
input only is used.
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
- Internal temperature is too high
- Loss of ground of head unit or amp

Specifications
CEA-2006 Compliant: CEA-2006 is
a new system of testing & 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 (THD) plus noise, and at 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 allows consumers to compare car amplifiers and receivers
on an equal basis.
Power:
Using the CEA-2006 guidelines listed above, the power output of the KAC-7202 is
150
watts RMS x 2 channels.
Kenwood also lists the following specifications:
- Power output at
2 ohms: 230 watts x 2 (1 kHz,
0.8% THD)
- Power output at
4 ohms, bridged: 460 watts x 1
(1 kHz, 0.8% THD)
-
Input impedance:
10k ohms
-
Operating voltage:
14.4 V (11-16V allowable)
-
Current consumption:
40A
