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.
Multi-Channel Design: The X700-5 is basically three amps
built into one chassis, two full-range 2-channel amps (A and B), typically
powering the front and rear speakers, and one mono amp to power a subwoofer.
Either of the full-range amps can also be bridged to one channel.
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 plus noise (THD+N), and over a frequency range of
20 Hz to 20 kHz (when applicable). 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 X700-5 is rated at 40 watts RMS x 4 plus 300
watts RMS x 1 with an 80 dBA signal to noise ratio.
Specifications: The manual also lists these non CEA-2006
- Full-Range Channels:
- 2Ω: 50 watts x 4 (at 1 kHz, no
more than 0.5% THD)
- Bridged: 100 watts x 2 (into 4Ω,
at 100 Hz, no more than 0.5% THD)
- Subwoofer Channel: 500 watts x 1-channel (into
2Ω, at 100 Hz, no more than 0.5% THD)
- Signal to Noise Ratio: 100 dB (at rated power)
Cooling Fan: There is a cooling fan to help dissipate heat
and ensure cool, reliable operation. Make sure not to block the vents or the fan
when installing the amplifier.
Input Sensitivity: The X700-5 features independent gain
controls for the front, rear, and subwoofer channels. The input sensitivity of
each is adjustable from 200 mV to 5.0 volts.
High-Pass Filter: The front and rear amps have individual
switches to set the built-in crossovers to high-pass or off (full-range). The
crossover points are independently adjustable from 50-200 Hz. The high-pass
crossover slope is 12 dB/octave.
Low-Pass Filter: The subwoofer channel's low-pass crossover
is always engaged (it cannot be bypassed). The crossover point is adjustable
from 50-200 Hz and the slope is 24 dB/octave.
Bass Boost: The subwoofer's 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.
Power And Ground Terminals: The amplifier features screw
terminal power and ground terminals. They will accommodate spade connectors up
to 0.55" wide.
Remote Turn-On Terminal: The remote turn-on is a screw
terminal that will accommodate a spade connector up to 0.35" wide.
Speaker Terminals: The five pair of speaker terminals are
screw terminals and will accommodate spade connectors up to 0.35" wide.
Signal Inputs: The amplifier features three pair of RCA
input connections, A, B, and Sub.
Fuses: Two 40-amp ATO fuses are installed in the amplifier
