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 methods 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 4-ohm load, with 1% or less Total Harmonic
Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz, when
applicable (20-200 Hz for this subwoofer amp). 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. Using
CEA-2006 criteria, the Kenwood XR600-1 is rated at 400 Watts RMS x 1 channel with a
78 dBA signal to noise ratio.
Specifications: The manual also lists these non CEA-2006
- Power: 600 watts x 1-channel (into
2Ω at 100 Hz, with no more than 1% THD, 14.4 volts)
- Signal to Noise Ratio: 100 dB (at
Mono-Power Amp Design: The Kenwood XR600-1 is designed with
specific features to power your subwoofers with a frequency range between 20 and
200 Hz. This amplifier is not designed to power a full-range speaker.
Class D Amplifier Design: The amplifier design is Class D,
which uses digital switching power supplies. The result is much higher
efficiency (less heat generated) than Class AB.
Low-Pass Filter: The XR600-1 has a built-in 24 dB/octave low-pass
filter, continuously variable from 50 to 200 Hz. The crossover is always engaged (it
cannot be bypassed).
Bass Boost: The bass boost circuit is centered at 40 Hz; boost
is variable from 0 to +18 dB.
Aluminum Heat Sink: The aluminum heat sink increases the
amplifier's heat dissipation efficiency, increasing the life of the amplifier.
- Input Sensitivity: 200mV-5V
- Low-Pass Frequency: 50-200 Hz;
- Bass Boost: 0-18 dB; continuously
Inputs and Outputs:
- Signal Input: one pair of RCA preamp inputs
- Preamp Output: one pair of pass-through RCA
preamp outputs; used to easily connect a second amplifier to the
same signal feeding the XR600-1's input
- Power: set screw terminal; accommodates bare
wire up to 4-gauge
- Ground: set screw terminal; accommodates bare
wire up to 4-gauge
- Remote Turn-on: set screw terminal; accommodates
bare wire up to 10-gauge
- Speaker Output: two pair of set screw terminals;
accommodate bare wire up to 10-gauge; the two outputs are internally
wired in parallel, making it easy to connect two subwoofers
- Fuses: three 30 amp mini blade fuses
