Our Cal Spa came with a radio/CD player originally, and has 4 waterproof Sony speakers, one in each corner. At some point the display portion of the audio unit was removed by the previous owner. I finally contacted Cal Spas and they do not sell a replacement display for that tub anymore.

So the question is there anything special safety or otherwise with hot tub radios? I could pull out the old unit and make a mount for a regular aftermarket car or probably better yet a marine radio. I figure so long as it's powered via the factory 12 volt supply or an aftermarket spa rated 12 volt adapter it should be safe. The radio would be mounted under a flap on the outside of the spa, not directly accessible from a user in the spa. This seems safe to me, but am I missing anything?

Don't know about mounting a stereo. I would think a marine radio would be safe, but they make a blue tooth stereo that mounts inside the shell.

J,

You could put a 12 volt radio in the water and it would be "safe".. Might not last long underwater, but it would not be a safety issue.. :mrgreen:

Thanks,

Jim R.

I figured the safety part was all in the appropriately rated and isolated 12 volt power supply, not the radio, but I wanted to make sure I wasn't missing anything.

Should I say, mounts under the skirt? Between the skirt and shell.
There's a smoked plastic flap in the skirt the pops up for access to the radio. The radio itself mounts between the skirt and shell, just to the right of the equipment bay.

My Sundance Spa came with radio/cd player but it was a boat type..... perhaps more waterproof? It gave up working about 5 years in though...... :(
