Great service from caraudiocentre. Arrived very quickly, well packaged. Good amplifier. Driving an eight inch sub and front component speakers. Have used caraudiocentre. A few times, each time is a faultless service.

Questions/Answers About This Product
  • Question: 28 August 2018
    Does PMX F640 fit well with ALPINE R S65C ?

    Answer: 
    hi,

    yes this amplifier would work with the alpine speakrs, although they can take more power you could always use the full 4 channels for the speakers and run them bridged to get more output

    Found Useful? Yes 

  • Question: 15 July 2018

  • Question: 18 April 2018
    Car: Alfa Romeo 147 - 2000-2007

    Pioneer TS-W3003D4 12" Champion series PRO subwoofer 4ohm DVC 2000 watts ...did this amplifier can run this subwoofer???

    Answer: 
    hi,

    no this this amplifier PMXF640 is a 4 channel amplifier which is really designed for speakers and maybe a small very low power subwoofer, for something like the subwoofer you have we would recommend something like the GMD8601 as at 2OHMs it will give you 500Wrms which is very close to the power required for the subwoofer

    Found Useful? Yes
