Questions/Answers About This Product
  • Question: 27 September 2021
    I asked the question below regarding the Tirunoh TR6.
    I was planning on buying the speakers with the amp - so any advice is welcome.
    Also, the car is Negative earthed. Is this an issue?


    Below are good speakers.
    It would also depend on how much space you have in your car for the speakers. The below are 4".

    Also, it would be an issue if it was Positive earthed. Negative earthed is fine.

  • Question: 25 September 2021
    Would this amp work well powering two 6x9's?
    Its for the back of a Triumph TR6, so its quite loud.
    I imagine I can still run the two forward speakers from the stereo itself?



    Which speakers do you have? Need the specs of the speakers to advice further.
    Yes, two forward speakers can be run through the stereo directly, provided the stereo supports it.

    Found Useful? Yes 

  • Question: 13 September 2021
    Would this amplifier be enough to run 6 x Pioneer T-SR6951S speakers?

    Hi there,

    It is never recommended to run 6 speakers through one amp. But if you insist on doing it, you will need something like this :-
