The mObridge MOST150 Amplifier has been specifically designed for MOST150 audio systems to interface seamlessly into the vehicle bus network for unprecedented control and audio reproduction.

Blackfin DSP

The heart of the device is a 533MHz Blackfin Digital Signal Processor (DSP). With it, the mObridge MOST150 amplifier is capable of concurrently running advanced DSP algorithms on all 8.1.1 channels. It provides full access to channel mapping, channel summing, parametric crossovers, a 1024 point graphic equalizer, channel high/low/band-pass filters, phase inversion, time alignment, master/channel gain control, centre channel upmixing algorithms, in-vehicle preset control, and many other features.

8.1 Channel Amplification with Additional Subwoofer Pre-out
The mObridge MOST150 amplifier features 8x full-range outputs, a dedicated subwoofer channel, and an additional subwoofer pre-out – perfect for all other aftermarket amplifiers.

  • 6x 150W Channels @ 4ohms | 75w RMS
  • 2x 300W Channels @ 4ohms | 150w RMS
  • 1x 500W Subwoofer Channel @ 4ohms (or 800W @ 2 Ohms) | 250w RMS & 400w RMS
  • 1x 4V RMS RCA pre-out
  • <0.003%THD
  • 105db SNR

The subwoofer pre-out provides a 4V RMS output to give you the flexibility to add a secondary powered subwoofer to enhance your audio experience further.

Ultra Efficient Sound

This amplifier runs a 4-phase, intelligent variable power supply feeding with top of the line D Class chips that run at over 90% efficiency this allows for a surprisingly small form factor while also packing some serious punch. Because of the advanced gate drive correction of these chips, not only is this amplifier super efficient, it also recreates sound with near perfect accuracy. This amplifier is perfect for a stealth install to keep that factory look while also providing breath taking sound.

Seamless Integration

The mObridge MOST150 amplifier interfaces seamlessly with the controls of the vehicle. Volume, fade, balance, bass, and treble remain completely controllable via the existing vehicle controls, and all factory audio such as parking sensors, navigation, voice, and telephone are integrated to behave exactly as per the original system. This means that unlike other integration options, there is no need for mounting of any additional controls inside the vehicle. The vehicle will look and feel stock, with exceptional audio quality.

mObridge DSP User Interface

The mObridge MOST150 amplifier utilizes the mObridge DSP desktop application for Windows/macOS to harness the full potential of the DSP. The application is also able to provide automatic online firmware updates.
