The MTXRTU8P is the ultimate combination of quality bass and amazing value. You won’t find a better performing under-seat subwoofer system at this price point!

The thick aluminium construction ensures it’s ultra-rigid, doesn’t vibrate and doesn’t mind the odd kick or two when fitted under a seat.

The built in 150W RMS amplifier features Class A/B technology so you can be assured it won’t mess with your radio reception. (Class D amps are known to effect digital radio reception)

High-level inputs allow the amplifier to operate from source units with speaker-level outputs. The RCA inputs are used with source units that have RCA or line-level outputs.

On the control panel, you will find a gain control (0.1V to 4V), bass equalizer (0 to + 12dB), the active 18db / Oct low-pass filter variable from 50Hz to 150Hz, the phase switch (0 ° or 180 °) and the EBC remote control port.

  • 8" subwoofer
  • Remote bass control included
  • High and low level inputs
