Instruction Disclaimer
Dennis Kirk provides instructions to help our customers better understand how
to install the products we sell. The instructions are exact copies of what the
manufacturer includes with the product being sold.
That means the quality and accuracy of the instructions is solely dependent on
what the manufacturer produces. We do our best to make the text legible and
the pictures viewable. However, the end result depends largely on the quality
of instructions the manufacturer provides.
Therefore, you will find that some instructions are not of the highest
quality. Sometimes text is hard to read and pictures are not easy to see. At
times you will find the overall look of the instructions to be less than
professional. However, we feel it is better to provide what we have rather
than provide nothing at all.
To the best of our knowledge the instructions and application information
contained in the instructions is accurate. However, Dennis Kirk assumes no
liability related to any errors that may be contained in the copy of the
manufacturer’s instructions we provide. Buyers are solely responsible to
insure that product use is consistent with their application.

CONTROL FUNCTIONS
-
Wiring Harness – All wiring to the amplifier will run through the wiring harness.
Speakers – Connect speakers/subwoofers to these terminals. Be sure to check wire for proper polarity. Never connect the speaker cables to the chassis ground.
+BATT (+12 Volt Power) – Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery. WARNING: Always protect this power cable by installing a fuse or circuit breaker of the appropriate gauge within 18 inches (45cm) of the battery terminal connection.
Remote Turn On – This terminal turns on the amplifier when (+) 12 volt is applied to it. Connect it to the remote turn on lead of the head unit or signal source.
GND – Connect this cable directly to the frame of the vehicle. Make sure the metal frame has been stripped of all paint down to the bare metal. Use the shortest distance possible. If a suitable ground point is not available on the frame, connect this terminal directly to the vehicle battery ground terminal or any other factory ground points.
RCA Input Jacks – This unit is designed to function with source units that feature either RCA or speaker level outputs. If using RCA cable connections from a source unit put the input level switch in the low level position. If connecting RCA cable connections from a speaker terminal put the input level switch in the high level position. A source unit with a minimum level of 200mV is required for proper operation. -
Gain Control – The Gain control will match the amplifier’s sensitivity to the source units signal voltage. The operating range is 10V to 200mV. NOTE: This is NOT a volume control.
-
X-Over Mode and Frequency Control (Full Range) – These controls allow control over the frequencies played. There is an option for Low Pass, Full Range, or High Pass. In LP or HP mode, the crossover frequency will be set at 80Hz.
-
Input Level – This slide switch selects between low level (RCA) inputs which provide 200mV – 5V input signal and high level (speaker level) inputs which provide 400mV – 10V input signal.

INSTALLATION AND MOUNTING
MTX recommends your new Thunder Sports™ amplifier be installed by a 12 volt
installation specialist.
Any deviation from specified installation instructions can cause serious
damage to the amplifier, speakers and/or vehicle’s electrical system. Damage
caused from improper installation is NOT covered under warranty. Please verify
all connections prior to system turn on.
- Disconnect the vehicle’s negative battery cable.
- Determine the mounting place for your MTX amplifier. Keep in mind there should be sufficient air flow for proper cooling. Mark the mounting holes from the amplifier to be drilled. Before drilling make sure all vehicle wires, gas lines, brake lines and gas tank are clear and will not interfere with installation. Drill the desired holes and mount the MTX amplifier.
- Install a positive (+) power cable from the vehicle’s battery through the firewall using a grommet or firewall bushing to avoid cable damage from sharp edges of the firewall. Run the cable through the interior of the vehicle and connect it to the amplifier’s +12V wire. Do not connect to the battery at this time. NOTE: Use only proper gauge wire for both positive and negative connections.
- Install a circuit breaker or fuse within 18 inches of the battery. This effectively lowers the risk of severe damage to you or your vehicle in case of a short circuit or accident. Make sure the circuit breaker is switched Off or the fuse is taken out of the fuse holder until all connections are made. Now connect your positive power cable to the positive battery terminal of the battery.
- Grounding – Locate a proper ground point on the vehicle’s chassis and remove all paint, dirt or debris to reveal a bare metal surface. Attach the amplifier’s ground wire to that contact point. If a suitable location is not available connect this terminal to the vehicle’s negative battery terminal.
- Connect a Remote Turn-On wire from the source unit to the MTX amplifier’s (REM) wire. If the source unit does not have a dedicated Remote Turn-On lead, you may connect to the source unit’s Power Antenna lead.
- Supply the signal to your MTX amplifier by connecting the signal cables using high quality RCA to the corresponding outputs at the source unit or speaker leads and inputs of the amplifier.
- Connect your speakers to your MTX amplifier’s speaker wires using the correct gauge speaker wire. Your MTX amp can drive a 2Ω stereo/4Ω bridged minimum load for optimum power.
- Double check all previous installation steps, in particular, wiring and component connections. Once verified, reconnect the vehicle’s negative battery cable, turn the circuit breaker On or place the fuse in the fuse holder.
NOTE: Gain Levels on the amplifier should be turned all the way down (counter clockwise) before proceeding with adjustments.
INSTALLATION
For proper performance and safety, MTX recommends installing an inline fuse
per the owner’s manual instructions according to the following.
