Caldera Spa popping/crackle noises
dpeters:
Have a 2018 Caldera tahitian with sound system and subwoofer. About 2-3 months ago started getting awful popping or crackling noises from the subwoofer. Would start with just a few pops, then at times would continue for a hour. All times of the day/night. We did have a handrail installed screwed into the frame of the spa. And seems to have started after this was done. Have had spa techs out 3 times and can not find what is causing the noises.
This past week have removed the handrail and now we are just hearing a single or double popping noise roughly every 10 minutes. The constant noise has stopped with handrail off.
I do have audio of the sounds Also do see there was a leak over one of the pumps caused rust buildup , and also the bottom of the heater looks rusty
Has anyone ever had this issue?
Hottubguy:
Is the music system on or off when you are in tub?
dpeters:
The ‘noises’ occur when we are not in hot tub. Can be in the house. And hear it

Is there an on/off switch inside the stereo enclosure? most subs will have a volume control built in that can be turned down a bit. https://manualzz.com/doc/29173345/stb-bluetooth-subwoofer-pairing-instructions
WITH NO MUSIC OR SOUNDS PLAYING, SYSTEM MAY EXHIBIT LOW LEVEL BACKGROUND NOISE DUE TO BT SEARCH FUNCTION. TURN THE POWER SWITCH “OFF” WHEN NOT IN USE.
