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.
Inputs, Outputs and Controls
Class A 100% Discrete Driver
Circuitry Topology: The preamp stages use Class A topology for low
distortion and a high damping factor; the result is tight, controlled bass.
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.
Smart-Engage: When using the
speaker-level input, the amp automatically turns on when it senses signal from
the head unit, eliminating the need for a remote turn-on connection. In many
cases, this feature will allow you to install the amplifier without the need to
remove your radio.
Internal Crossovers: There is
one crossover for the front channels and another for the rear channels. The
crossover for the front channels may be set for 85Hz, 18dB/octave high-pass
operation, or it may be turned off for full-range operation. The crossover for
the rear channels may be set for 85Hz, 18dB/octave high- or low-pass operation,
or it may be turned off for full-range operation.
Buffered, Isolated RCA Output:
In addition to the front and rear sets of preamp inputs, there is a set of
full-range summed RCA preamp outputs. The outputs allow you to daisy-chain one
amplifier to another.
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 you amp is operating within safe
parameters for maximum power and protection.
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.
Left Side of the Amplifier
- Front and Rear Variable Gain
Controls: the gain controls allow you match the input sensitivity of the amp to the particular source unit you are
- RCA Input Select Switch: a
switch used to match the amp's input to the source unit's output so all four
channels of the amp are driven. If your source unit has 2 outputs (a left
and a right), connect them to the amp's front channel inputs, and place the
input select switch in the 2CH position. Likewise, if you are using a
4-channel source, place the input select switch in the 4CH position. In the
4CH position, the fader on your source unit will operate.
- Front left and right RCA input
- Rear left and right RCA input
- RCA Sum Out Jacks: RCA
preamp output jacks, which allow you pass summed, full-range signals from
this amplifier to another amp in a daisy-chain configuration
- Front Crossover Switch: lets you
select high pass or full range operation
- Rear Crossover Switch: lets you
select high pass, low pass, or full range operation
- Front and Rear Speaker Level
Inputs: two 4-pin
inputs for use with the included speaker-level input harnesses; allow the amp
to operate with source units that do not have preamp outputs
Right Side of the Amplifier
- Speaker Outputs: these
terminals are configured like steps, with the rear left and right outputs in
a row below the front left and right outputs (0.34" wide)
- BATT (power): screw terminal
(terminal is 0.54" wide)
- GND (ground): screw terminal
(terminal is 0.54" wide)
- REM (remote turn-on): screw
terminal (terminal is 0.34" wide)
- Fuses: slots for two 25-amp
blade fuses (fuses are included)
