Features

1. Prizm EFX – All MTX amplifiers include backlit adjustment controls on top surface of product.

• Color – The backlit controls offer unlimited colors on the display -- from RED, GREEN, BLUE, or any color
in between.

• EFX – You can switch Prizm EFX lighting to “pulsate” with beat of music.

2. Xtant Technology Cooling (XTC) – thermal-regulated turbo-charged inner cooler, 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 all volumes.

3. Bi-Level Inputs with Smart Engage – All MTX amplifiers feature RCA type input connections. All MTX
amplifiers allow both high level and line level input into the RCA type input connections.

• Low Level Input – All MTX amplifiers feature RCA type input connections. Source units with an output
signal level of 100mV–10V may be used. See “Input Sensitivity” for proper voltage level setting.

• High Level Inputs with Smart Engage – All MTX amplifiers allow high level inputs through RCA type input
connections using provided high level adapters. Source units with an output signal level of 100mV–10V may
be used. See “Input Sensitivity” for proper voltage level setting.

• Smart-Engage” Auto-turn-on: is an auto turn-on circuit included within the amplifier. A remote turn-on
wire is not necessary when connecting the amplifiers high-level input to a high-powered source unit (Car
Stereo). The amplifier will automatically turn on when music is received through this type of connection.

Note: Smart engage is only active on the left input.

4. Input Sensitivity –The Input Sensitivity switch is used to set the proper input voltage range:

X1 POSITION: 100mV – 1V (Typically for RCA Input)
X10 POSITION: 1V – 10V (Typically for Speaker Level Input)

5. Stereo Gain Control – This feature is used to fine-tune the input sensitivity of the amplifier to the source unit’s
output level.

6. Switchable Hi, 12dB/Low, 24dB X-over – This switch is used to pick the preferred frequency range the amplifier
will play. A high-pass or full range output may be selected for the front output. A high-pass, low-pass, or full
range output may be selected for the rear output. The upper end of the low-pass crossover is 85Hz at 24dB
per octave with a mono output. The lower end of the high-pass crossover is 85Hz at 12dB per octave with a
stereo output.

7. Dual Mono Output (low pass only) – This feature is used when driving subwoofers and the amp is wired in a
bridged front and bridged rear configuration (2-channel) or all channels combined configuration (1-channel) to
ensure all channels receive the same signal.

8. Summed Front/Rear Line Level Output – This line level output is used to send a signal to an additional
amplifier. The signal is not affected by front rear fading.

9. Remote Subwoofer Level Control (Remote Sub) – This port allows the use of the optional “remote level
control”. . The Remote Subwoofer Level Control is a bass control module that can be installed in any location
within the vehicle for remote adjustments.

10. StreetWires Connectors – All MTX amplifiers include StreetWires connectors for efficient current and
maximum voltage transfer

11. Speaker Connection – These output terminals are individually labeled for proper speaker connections. When
bridging the amplifier, use the left positive terminal and the right negative terminal only. Warning, do not
individually bridge the front and/or rear of the amplifier with an impedance lower than 4 Ohms.

12. Power Terminals – This is the main power connection for the amplifier. The power and ground wire size
should be the same gauge.

• GND – The ground wire from this connection must be attached to bare metal on the vehicle.

• REM – To turn the amplifier on/off, this terminal must be connected to the source unit’s “remote or electric
antenna” wire.

• +12V – The power wire from this connection must be attached to the positive side of the vehicle battery.

Before Starting

MTX recommends that you have your new Thunder amplifiers installed by an authorized MTX retailer, preferably

MECP certified. If you do decide to do it yourself, make sure you have read the instructions carefully, and that
you have the following tools:

• Electric drill • Phillips bit or Screwdriver

• 1/8” bit • Wire cutters/crimpers

• Safety Glasses • X-acto Knife

Disconnect the vehicle’s negative battery connection. Any deviation from the recommended connection

procedures may cause serious damage to the amplifier, speakers and/or vehicle electrical system. Please
double-check the connections before turning the system on.

Installation - Mounting

Place your Thunder amplifier at the predetermined mounting location. Using a felt pen, mark the exact position of

the mounting holes on the mounting surface. Set the amplifier aside then with a sharp, precise blade cut small
circles in the carpet and padding around the four marks denoting your mounting holes to expose the metal
underneath. Use a center punch to make an indentation in the metal to ensure that you drill the exact position
for the screws.

Note: Please use common sense and make sure that all vehicle wires, gas lines, break line, etc... are clear and will

not interfere with the installation. ALWAYS WEAR PROPER SAFETY GLASSES.
