Phase Test

Do this test to confirm proper speaker phasing.

  1. Insert audio diagnostic CD (T/N 07AAZ-SDBA100) into the CD player.
  2. Play track No. 2 (phase) at a normal, or slightly higher than normal, volume level.
  3. The voice should sound centered and focused when it is in-phase.
  4. The voice should sound diffused, and have "less bass" when it is out of phase. If the voice changes from in-phase to out of phase as indicated by the prompt, the phasing is correct. Go to «ELECTRICAL NOISE TEST»(/acura/tsx/i-2003-2008/remont/entertainment-systems/#audio-system__electrical-noise-test) . If the voice always sounds out of phase, phasing is not correct.
