The all new Road Thunder series amplifiers are the culmination of years of experience in design to deliver the ultimate in performance and value. Outwardly the Road Thunder series amplifiers utilize clean lines with a brushed aluminum finish that complements any installation in any vehicle. Internally these amplifiers are designed to outperform all other amplifiers in their class.

The class D mono blocks utilize patented MTX technologies like Adaptive Class D topology and Smart Engage circuitry to ensure to deliver excellent sound quality in an easy to install package. Additionally, these models feature a dual layer printed circuit board that has twice the amount of copper as similarly priced amplifiers that use a single sided board. This results in improved THD+N as well as signal to noise ratio. The feature set for these models include an adjustable low pass crossover with a 24dB/octave slope, an adjustable bass boost up to 12dB, a subsonic filter for improved subwoofer performance when using a vented enclosure, and each model includes an external bass control. All of these features are loaded into MTX’s smallest amplifiers yet.

The full range amplifiers deliver excellent performance as well. These class A/B models have excellent sound quality reproduction in a small chassis size as well. These models are both full range and include a selectable low pass, high pass, or full range mode which accommodates any installation and listening style. Both models feature both a low pass and high pass crossover as well as speaker level inputs for easy install.

ISMT (Mono Models Only)

ISMT is a method of designing and manufacturing products. The parts in ISMT are actually mounted on the Surface of the amplifier circuit board, rather than through the board. The components surface mounted on the amplifier circuit board during the ISMT process are highly resistant to vibration and can withstand the abuse of the automotive environment. ISMT is a whole lot more than just a new cool way to put parts on a circuit board. Our MTX electrical engineering brainiacs use ISMT to its greatest potential - from board layout, to the selection of components. Technology is the tool that makes sure that your amplifier is the best it can be.

Advanced Computerized Protection Circuit for maximum power output and protection
Class A 100% Discrete Driver Circuit Topology is linear, resulting in low distortion and a high damping factor for tight, controlled bass
Patented PWM Mosfet Switching Power Supply for superior sonic performance
Low Impedance, High Power Transformers provide more power and produce less heat

Smart Engage (Mono Models Only)

Smart Engage Auto Turn On is a technology incorporated into MTX amplifiers that makes them easier to install and easier to use. Smart Engage allows the amplifier to be installed without the need of running a remote wire from the head unit to the amplifier. You can tap into the vehicle's speakers anywhere in the vehicle with an RCA connector that has one end of RCA's removed, then run the other RCA connector into the amplifier and once the speaker receives voltage from the head unit, the amplifier will automatically power on. This is especially convenient if you are adding an amp and sub to your trunk and do not want to mess around with removing the head unit. You can tap into the rear door or deck speakers and run the RCA to the amplifier. Add your power and ground wires and your system is ready to rock.

Adaptive Class D Technology (Mono Blocks Only)

Class D amplifiers are pretty common these days. It seems like everybody has one. Let's discuss the common approach. Amplifiers that use Class D technology are switching amplifiers. These amplifiers feature MOSFET transistors that operate as a switch and are used to manage the power applied to the speaker. The controlled switching power distribution creates a square wave known as Pulse Width Modulation. High frequency energy is generated from this square wave and is commonly concentrated at one point that must be filtered from the audio path of the amp. Harmonics from this concentrated high frequency energy travel into the radio frequency range, and can cause interference with the radio's reception or be picked up by the audio system's ground. That means NOISE. MTX changed the rules with our innovative, new Adaptive Class D Technology. With our approach, the amplifier's switching energy is constantly changing and is moved away from FM radio frequency ranges as the amplifier's load and output increases. This ensures that the harmonics do not interfere with the radio's reception and are not picked up by the audio system's ground. This improves the amplifier's overall signal-to-noise ratio, and eliminates interference that is generated by more common Class D amplifiers. In other words, listeners can enjoy all the clean, musical sounds from the radio without the interfering noise of the Class D amplifier. Technology. What a great thing when you use it right.

Adaptive Class D Technology can be found on many MTX mono block amplifiers including: Thunder Elite, RoadThunder, RFL, and Terminator
