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: The KAC-7204's power ratings are
measured according to the strict standards dictated by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output of all CEA 2006-compliant amplifiers, even if they come from
different brands. Manufacturers who adhere to the standards can display the CEA
2006 logo on their products and packaging.
Speaker Level Input:
The
KAC-7204 comes with a two channel 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.
Signal-sensing Turn-On Circuitry: When the speaker-level
input is used, it is not necessary to connect the power control wire (turn-on
lead). The amplifier senses the signal from the speaker-level input and turns
the amplifier power on automatically. Shortly after no signal is detected, the
amplifier will automatically shut itself off.
Crossover: The amplifier has a three-way filter switch,
allowing you to choose low-pass (LPF), high-pass (HPF), or full-range (Filter
Off) operation. There are rotary controls for both Low Pass and High Pass cutoff
frequencies, allowing you to select them separately.
Bass Boost: You can apply a bass boost of up to +18dB at
40Hz. The rotary control is located on the front of the amplifier.
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
Fan Cooled: The KAC-7204 is equipped with two, rear
panel-mounted cooling fans. One fan acts as an intake while the other serves as
an exhaust to create a current of cooling air flowing through the inside of the
amplifier.
