TR Terminator 300W RMS @4Ω 4-Channel Class-AB Amplifier with Variable Active X-overs


The MTX TR450 amp is powerful and very flexible. It can power up 4 speakers (2Ω ~ 8Ω), 2 speakers plus a 4Ω subwoofer on two channels in bridge mode, or two powerful speaker or two subwoofers with its 4 channels in bridge mode.

It shines with its legendary dynamics and exceptional musicality. It has nothing to do with the microscopic amplifiers without switching power supply that equip factory or aftermarket headhunts... In bridged mode, the TR450 can power up a 4Ω subwoofer. Its active x-over allows you to use it for speakers or for subwoofers: 12dB/oct high pass or low pass at 80Hz. It is very simple.

To avoid interference problems, we have equipped the TR450 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 stereo does not have RCA outputs, you can connect the TR450 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 allows you to adjust the level of your 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

Recommanded MTX speakers: TR series or TX2 series or TX4 series or TX6 series speakers

Recommanded MTX subwoofers: RT10-04 or RT12-04 or RT15-04

Recommanded MTX enclosures: RTE12AS or RTT12AV or RTF10AS


The quality of your system will be the quality of your system weakest link. You have to balance your system with quality speakers (MTX TR TX2 TX4), a reliable musical and dynamic amplifier (MTX TX2450), 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 minute/day
