Ask a Question
  • is the blue wire a ground?

    The blue wire connects to the 12V turn on terminal located between the amps (+) & (-) terminals. The blue wire powers up the logo on the Rail CAP.

  • I am thinking about purchasing the Massive Audio BLX4 960 for my 2013 Harley Davidson Ultra Classic motorcycle. I want to know if this capacitor is a recommendation, or is there enough power from the bike to handle the amp?

    8 AWG would be ok 4 AWG if you have 2 amps
