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
