Welcome to our forum.
Thanks for all the info here. BTW, I had my tech out to install the stereo and subwoofer. While he was here, he showed me how to dim the logo and we set it to 25%. Much improved, but still bright enough to see in the daytime direct sunlight.I will send a suggestion to Watkins that they add a photocell and simple circuit to allow this logo to self dim based on the ambient light conditions. This would cost lest that $10 in parts and SHOULD be standard on these high end spas.
