Questions/Answers About This Product
  • Question: 23 April 2022
    Car: Porsche Boxster - <2008

    Yes, it has the original Porsche head unit but I wish to change to a pioneer single din head unit.


    That's fine. I just wanted to make sure as you would have needed a line out converter if you are changing the headunit

    Found Useful? Yes

    Car: Porsche Boxster - <2008

    Hi. I have replaced my dash speakers with Focal ES 100k. Can I power them with the above sub/amp and what accessories are needed?


    Yes, you can do that with these speakers. Are you running it from the factory headunit?
