Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, bear with us; re-confirm and post back with the complete model numbers of the headunit, the Bazooka and the 4 channel 400 amp.

Still, proposed preliminary checks (if have not been done) on the possibility of over/under-voltage issue. With a volt/multi-meter, determine the battery voltage when:

  • • ignition OFF and then when ON;
  • • when starting the engine;
  • • engine at idle;
  • • when engine RPM is increased.
