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.
PANEL LAYOUT
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.
TROUBLESHOOTING
FREQUENTLY ASKED QUESTIONS
Is this a 2 channel amp?****
Yes, it has a 2 channel amplifier.
Are MTX Thunder amps good?****
For driving subwoofers or full range speakers, THUNDER Series amplifiers deliver high power output at a reasonable price. These powerful yet small amplifiers are perfect for practically any placement or kind of speaker. The THUNDER Series, which are constructed with true MTX DNA, are the ideal option to Feel the Thunder.
Who makes MTX Audio?****
A family-owned American business that has been offering high-performance automobile, marine, home, and street audio equipment to clients in more than 80 countries for more than 40 years is the Mitek Consumer Electronics Group, of which MTX Audio is a member.
Does 4ohm sound better?****
4 ohm subwoofers will have a higher electrical resistance than subwoofers with lower resistance, use a lot less energy, and last longer as a result. Additionally, they are quieter than the 2 ohm ones.
Where are MTX amps made?****
MTX is a great option whether you want to upgrade your factory stereo or construct a world-class show car because their amps are hand-made in Korea using audiophile grade ELNA capacitors and subwoofers that use American Copper.
Which amplifier gives the best output?****
Class “A” amplifiers are regarded as the best class of amplifier design because, when constructed properly, they have great linearity, high gain, and minimal levels of signal distortion.
How many watts can MTX terminators handle?****
Each Terminator subwoofer can handle 200W RMS and is built with high-quality materials. Both Terminator sets offer unmatched value while providing steadfast performance.
Is MTX good speakers?****
Excellent entry-level speakers for limited funds. These MTX speakers have excellent sound quality. The mids bass is excellent, and the tweeters are clear.
Can you bridge a monoblock amp?****
Since it only has one channel, a mono block amplifier cannot be bridged. A mono block amplifier has two outputs that can be used to connect numerous subwoofers with ease. Look at the speaker terminals to determine whether your amplifier is a mono block or a multi-channel unit.
What does RMS stand for in audio?****
The waveform’s peak value, like the peak at the top of a mountain, represents the maximum voltage that it will ever experience. The effective value of the entire waveform is the RMS (Root-Mean-Square) value. It is equivalent to the DC signal’s amplitude at which the periodic signal’s average power would be produced.
How many ohms are MTX terminators?****
This subwoofer is a fantastic complement for a mono sub amp because to its 2-ohm impedance.
What does Sound Amplifier do?****
Playing both audio and video on your device is possible using Sound Amplifier. The audio from any films or music you play on your device can also be adjusted. Android 10 Pixel phones can choose this option. Find out how to check and upgrade the version of your Android.
Does an amp make sound better?****
An amplifier is made to boost the levels of audio signals. However, neither the recorded audio nor the reproduction of such audio is meant to be improved, either objectively or subjectively.
