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.
Features
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 (THD) plus noise, 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 X500-1 is rated at 300 Watts RMS x 1 channel with an
83 dBA signal to noise ratio.
Specifications: The manual also lists these non CEA-2006
compliant specifications:
- Power: 500 watts x 1-channel (into
2Ω, at 100 Hz, no more than 0.5% THD, 14.4 volts)
- Signal to Noise Ratio: 100 dB (at
rated power)
Mono-Power Amp Design: The Kenwood X500-1 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 X500-1 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.
