Chapter Twelve: Stereo - Jacuzzi Z Builder Series Mechanics And Repair

Chapter Twelve: STEREO:

Spas with stereos use car stereos. The spa has a transformer that changes the
voltage from AC to DC and lowers the voltage to 12 volts. Jacuzzi used major
brand car radios to add music and outdoor speakers.
Some stereos pick up noise when on AM but not FM. I have found the common
problem is the step down transformer is the cause. If you purchase a quality
transformer with "clean" current this can remove the noise.
