Inputs, Outputs, & Controls
Patented PWM MOSFET Switching Power Supply:
This type of power supply is used for maximum power output and
Adaptive Class D Technology: While
typical Class D amps tend to generate high frequency energy that must be
filtered to prevent harmonic interference in the FM radio frequency range,
Adaptive Class D Technology directs the amp's switching energy away from FM
radio ranges as the amp's load and output increases. This improves the amp's
overall signal-to-noise ratio and eliminates interference generated by more
common Class D amps.
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.
Low Impedance, High Power
Transformers: These provide more power and produce less heat.
Smart-Engage: If you're
planning to keep your factory radio and use the amp's speaker level inputs,
Smart-Engage senses the source voltage from the factory radio, meaning you won't
have to run a separate turn-on lead and won't necessarily have to remove the
factory radio during installation.
Real-time Computerized Protection Circuit:
The protection circuit makes sure you 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.
Rubber Insulated 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.
Isolated RCA Outputs:
In addition to the set of preamp inputs, there is a set of full-range RCA
preamp outputs. The outputs allow you to daisy-chain one amplifier to another.
Also, the RCA output jacks allow for multiple bass amplifiers to be level
controlled using one EBC (sold separately).
(Electronic Bass Control) 2: This amplifier includes an Electronic Bass
Control Port that will accept the cable from an optional EBC. When an EBC is
connected, you have access to an additional 3dB of gain and 23dB of attenuation
from the driver's seat. If the optional EBC is installed, the bass level will be
able to be adjusted 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.
Thunder EQ: Thunder EQ is a continuously
variable Bass Boost (0-18 dB) centered at 40 Hz.
Crossover: This amplifier
includes a 24dB/octave, low-pass crossover that is always active. There is a
crossover frequency control, continuously variable from 40 Hz to 200 Hz, that
allows you to dial in the low-pass cut-off frequency of your choice.
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.
Peak (Dynamic) Power (measured
at 14.4 Volts DC):
- 450 Watts x 1 into 4 Ohms
- 775 Watts x 1 into 2 Ohms
Outputs, & Controls
- Gain control: allows you to
input sensitivity of the amplifier to the particular source unit you are
- Thunder EQ Control: a rotary
control that allows you to set the bass boost applied to the speaker output
- Frequency Control: a rotary
control that allows you to select a low-pass crossover frequency from 40 Hz
to 200 Hz
- Left and Right RCA
- Left and Right RCA output jacks:
RCA preamp output jacks, which allow you pass full-range signals from this
amplifier to another amp in a daisy-chain configuration
- EBC Port: this is a
phone-style jack made to accept the cable from and optional EBC (Electronic
- Speaker Level Input: this is
a 4-pin input for use with the included speaker-level input harness; allows
the amp to operate from source units that do not have preamp outputs
- Fuses: slots for three
25-amp blade fuses (fuses are included)
- Power Terminal: (0.54" wide)
designed to accept cables as large as 6 gauge
- Remote Turn-on Terminal: (0.34" wide)
- Ground Terminal (0.54" wide)
designed to accept cables as large as 6 gauge
- Speaker Terminals: (0.34"
wide) there are two +/- pairs of terminals, but they are connected together internally and they provide mono output; if two 4-ohm speakers are connected, one to each set of terminals, the amplifier will see a 2-ohm load, because the terminals are internally connected, in parallel with each other
This amplifier accepts three 25-amp fuses, so its fuse rating (75-amps total) exceeds
that of the fuses included with many 4 gauge wiring kits. The highest AGU fuse values carried by Crutchfield are 70 and 80 amps. If you use a wiring kit that does not include an 80-amp fuse, the fuse included with the wiring kit should be replaced with an 80-amp AGU fuse (sold separately).
