MTX TR275 picture


TR Terminator 220W RMS @4Ω 2-Channel Class-AB Amplifier with Active -over


The MTX TR275 amp is powerful and flexible. It can power 2 loudspeakers (2Ω ~ 8Ω) of large diameters in the front, rear doors or on the deck. It shines with its legendary dynamics and exceptional musicality. It has nothing to do with the microscopic amplifiers without switching power supply that equip car radios ... In bridged mode (Bridge), it is capable of feeding a subwoofer or a 4Ω subwoofer. Its variable active filter allows it to be extremely precise: 12dB / oct high pass or variable low pass from 50 to 120Hz. If you don't know where to start adjusting the active filter, the potentiometer is equipped with an 80Hz "click" position. You can not be wrong. To avoid interference problems, we have equipped the TR275 with balanced inputs. They perfectly isolate the audio ground of the amp so that it does not mix with the noisy ground of the power supply. This is a powerful technique that is usually found on very high end amps. If your car radio is not equipped with RCA outputs, you can connect the TR275 to the high level inputs. All you need to do is connect the HP cables directly to the high level input of the amplifier. Simple and very practical. If you need it, the MTX EBC-1 remote control is available as an option. It can allow you to adjust the level of the subwoofer with a simple analog knob, sitting in the front seat. Finally, its design and construction are of remarkable quality. Its all-aluminum chassis is the same as that of the prestigious MTX TX6500D and TX81000D amps. We don't skimp on quality at MTX...

Recommended Efficient Associations

TR TX2 TX4 TX6 speakers - RT TX6 subwoofers


The quality of your system will be the quality of the weakest link. You have to balance your system with quality speakers (MTX TR TX2 TX4), a reliable musical and dynamic amplifier (MTX TX2275), a quality subwoofer (MTX RTE12AS RTE12AV RTF10AS…) and careful assembly.

Suggested System Diagrams



The power of the amplifier should not exceed that of the loudspeaker. You have to compare RMS powers with RMS powers. The amplifiers should not be exposed to moisture, excessive vibration, or high temperatures.


MTX wants you to enjoy your hearing for a long time. Excessive exposure to loud volumes can damage your hearing. The United States Department of Labor recommends not exceeding the following recommendations:
90db : maximum 8 hours / day
92dB : maximum 6 hours / day
95db : maximum 4 hours / day
97db : maximum 3 hours / day
100db : maximum 2 hours / day
102db : maximum 90 minutes / day
105db : maximum 60 minutes / day
110db : maximum 30 minutes / day
115db : maximum less than 15 minutes / day
120db : immediate danger, 0 minutes / day
