5-Channel Full-Range Amplifier:
The Jensen Power 2000.1D is a monoblock, class-D amplifier, designed to run
subwoofers. It comes with a Remote Input Level
Control that allows you to vary the volume of the amplifier from the
front seat of the vehicle.
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 at 10-300Hz bandwidth with 1% or less Total Harmonic Distortion plus noise (THD+N).
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. Following the CEA-2006 criteria, the
power ratings for the amplifier include:
- 425 Watts RMS x 1 channel into 4 ohms @ <1% THD+N
- 675 watts RMS x 1 channel into 2 ohms @ <1% THD+N
- 900 watts RMS x 1 channel into 1 ohm @ <1% THD+N
Note: The following manufacturer's power specs, displayed
on the box and in the manual, are measured @ 2% THD+N, 1 kHz, and 14.4 Volts DC:
- 450 watts RMS x 1 channel into 4 ohms
- 725 watts RMS x 1 channel into 2 ohms
- 1000 watts RMS x 1 channel into 1 ohm
Gain Controls: The Power 2000.1D features
a rotary gain control.
The line input will accept signals between 400mV and 4.0 Volts.
Crossovers: The amp has a continuously variable low-pass filter with a cutoff frequency
of 40Hz-300Hz. The low-pass filter cannot be defeated. In addition, a non-defeatable
10-40Hz subsonic filter cuts out ultra-low frequencies which rob power from the
amplifier and speakers can't reproduce.
Phase Switch: The Phase Switch lets you select the polarity
of the output at 0° (normal polarity) or 180°
(inverted polarity). To determine the appropriate phase setting, you should
perform a sound test with each setting and set the phase switch at the position
that produces the fullest and most dynamic bass.
Bass Boost: The amp features a continuously variable Bass
Boost, adjustable from 0 to +12dB, and centered at
45Hz. This allows different subwoofer/enclosure combinations to be equalized.
The control lets you increase the level of low bass available from the
subwoofer/enclosure combination. Ported and Bandpass enclosures should be
limited to about +6dB to +9dB of boost, while sealed enclosures should be able
to accept the full +12dB of boost, if necessary.
Power/Ground/Turn-On Terminals: The amplifier features
set-screw terminals for the power, ground, and remote turn-on connections. The Power and Ground
connections will accept up to 4 AWG power wire, while the turn-on lead terminal will
accept 18 to 8 AWG wire. A Phillips-head screwdriver (not supplied) is required for
tightening or loosening the set-screws.
Speaker Output Terminals: The Power 2000.1D amplifier's ten set-screw speaker terminals will accept 16 to 8 AWG
speaker wire. A minimum of 12 AWG speaker wire is recommended by the
manufacturer. A Phillips-head screwdriver (not supplied) is required for
tightening or loosening the set-screws.
Preamp Inputs/Outputs: The amplifier is equipped with a pair
of RCA jack inputs, and a pair of RCA jack outputs. The Preamp Outputs allow you
to pass the input signal to another amplifier (daisy chaining) without having to
run an extra set of patch cables from the head unit.
Remote Input Level Control: The amplifier features a 3.5mm connector for
connecting the supplied wired Remote Input Level Control. With Remote Input
Level Control, you can control the volume of all channels from the front of the
vehicle. If the amp is used to drive subwoofers, and the low-pass filter is
activated, the Remote Input Level Control can be used to control the bass level
independent from the rest of the system. The Remote Input Level Control has a
