The MTXTR450 is a small but powerful Class A/B amplifier. Designed to run two pairs of speakers or it can be bridged to power a couple of 4 ohm subwoofers like the MTXTR12-04. It has a small footprint measuring just 22cm wide and 13.5cm deep which means it can be installed practically anywhere!

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. This is a great starting point.

To avoid interference problems, the TR450 is equipped 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 much higher end amps.
If your car radio is not equipped with 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!
