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
Class A 100% Discrete Driver
Circuit Topology: The preamp stages use Class A topology for low distortion
and a high damping factor; the result is tight, controlled bass.
Power
Supply: This amplifier uses a patented PWM MOSFET switching power supply
for maximum power output and
protection.
Pure N-Channel Design: The pure
N-channel design is more linear than typical N-Channel designs, so the speaker
you connect to the amplifier will be better controlled. The signal travels
through fewer parts so the signal-to-noise ratio is enhanced, the power rating
is better, and the amp runs louder, longer.
Input Sensitivity: This
amplifier has independent left and right channel adjustable input sensitivity
controls.
Internal Variable Crossover:
The built-in crossover, variable from 40Hz to 200Hz, can be set for high-pass or
low-pass operation, or it may be turned off for full-range output. When set to
high-pass, the crossover has a slope of 12dB/octave, and the output is stereo.
When set to low-pass, the crossover has a slope of 24dB/octave, and the output
is mono.
Preamp Outputs: There is one
set of isolated preamp outputs for adding another amp. The output signal is can
be set for high-pass or low-pass at the same cutoff frequency of the amplifier's
internal crossover.
Thunder EQ: This equalization
circuit is used to enhance the amplifier's low frequency response. You can add
up to 18dB of boost centered at 40Hz.
EBC (Electronic Bass Control) 2: This
amplifier includes an Electronic Bass Control Port (RJ-11 jack) that will accept
the cable from an optional EBC (item # 236EBC). When an EBC is connected, you
can adjust the bass level from the driver's seat to overcome noise and other
interference. With EBC 2, multiple compatible amps can be controlled.
Intelligent Surface Mount
Technology: Features substantially shorter internal and external lead
lengths, reducing stray capacitance and inductance, which results in cleaner and
more accurate musical reproduction with less noise interference.
Real-time Computerized Protection
Circuit: The protection circuit makes sure the amp is operating within safe
parameters for maximum power and protection.
Acoustically Seamless
Turn-on/Turn-off: A circuit that prevents turn-on/turn-off "thump"
is included to eliminate turn-on/off noise.
Iso-Feet: Four rubber Iso-Feet
are attached to the amplifier. The rubber feet let you mount the amp securely,
while preventing the mounting screws from coming into contact with the amp's
chassis; this helps prevent ground loops.
Terminals: The terminals are
nickel-plated, heavy-duty screw terminal connectors.
Performance Certificate: MTX
tests each amplifier, and the technician records the "actual" power
output on the Certified Performance Certificate included with each amp. The amp
must meet or exceed the rated specification in order to leave the factory.
