Inputs and Outputs Notes
Prizm EFX: With the MTX Prizm EFX, you can adjust the
color of the display to match your vehicle interior. The display color can be
set to red, green, blue, or any color in between. If desired, you can switch
Prizm EFX lighting to "pulsate" with the beat of music.
Xtant Technologies Cooling (XTC): The Xtant
Technologies Cooling (XTC) thermal-regulated, turbo-charged intercooler supplies
fan forced cool air evenly and constantly through tightly packed, bonded fins.
Fan speed is continuously variable and controlled by amplifier's output load,
temperature of heatsink, and transformers. Exhaust of internal heatsink is
strategically positioned to cool transformers to maintain maximum performance at
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.
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 removing
Quasi Parametric Equalizer:
This one band equalizer provides individual frequency and -/+ 12 dB gain
adjustment controls. Any frequency from 30 Hz to 80 Hz can be boosted or cut up
to 12 dB.
Bass Control: The External Bass Control lets you adjust the output level of
the amplifier from anywhere in the vehicle. When attached to the mounting
bracket, the External Bass Control has the following dimensions: W=1.602",
H=0.979", D=2.578" (including the knob).
Variable Low-Pass Filter: The
internal low-pass filter can be adjusted from 40 to 200 Hz, and has a slope of
24 dB per octave.
Subsonic Filter: The subsonic
filter is used to remove low frequencies that you cannot hear but can "rob"
power from the amplifier. The crossover point is fixed at 30 Hz, and the filter
can be turned on or off.
Bi-level Inputs: The RCA inputs
will accept both speaker-level and line-level signals. To accept speaker-level
input, you must use the supplied high-level adapter cables.
Capacitor Terminals: This amp
provides power and ground connections for an optional capacitor.
Input Sensitivity: The input
sensitivity switch can be set to x1 (line-level input) or x10 (speaker-level
input). When set to x1, the input sensitivity can be adjusted from 100mV - 1V.
When set to x10, the input sensitivity can be adjusted from 1V - 10V.
Performance Certificate: MTX
tests each amplifier, and the technician records the "actual" power output on
the Thunder Amplifier Dyno Certificate included with each amp. The amp must meet
or exceed the rated specification in order to leave the factory.
Inputs and Outputs
Set-screw Terminals: The power
and ground set-screw terminals will accept up to 4-gauge wire. The remote
turn-on, capacitor, and speaker set-screw terminals will accept up to 8-gauge
RCA Inputs: The RCA inputs will
accept both speaker-level and line-level signals. To accept speaker-level input,
you must use the supplied high-level adapter cables.
Remote Gain: This minijack
allows you to connect the supplied External Bass Control.
Wiring Kit Fuse Ratings:
This amplifier uses three 25-amp fuses, so its total fuse rating is 75 amps. The
Streetwires 4-gauge amp wiring kits include an 80-amp fuse, which will
accommodate the amp's fuse rating. Other 4-gauge amp wiring kits carried by
Crutchfield include a 60-amp fuse. If you are using a 4-gauge amp wiring kit
with a fuse rated for less than 75 amps, the fuse should be replaced with an
