LED controller causing humming in speakers

[dpostman21]

After the installation of the 6.5” Enrock speakers with LED ring I have a pulsing noise in the sound system, does not do it when speakers are on solid colors just when it cycles thru the colors. I have installed a Superbright LED controller (TQ Nusic 2 RF controller), since then the noise is annoying.

Controller thats cause noise: https://www.amazon.com/gp/product/B00JQ3QOSY/ref=oh_aui_detailpage_o01_s02?ie=UTF8&psc=1

I have a the XGlow LED system installed as well and don’t experience the same level of noise in the sound system a slight hum at low volume. This controller is WiFi based and not RF.
I have ran new 14 AWG speaker wire and 14 AWG power/ground wires to the speakers & RF controller. Power goes to brand new Blue Sea 5 circuit fuse block which is powered by the common on the battery switch and grounded to the battery I have a 4 AWG power to fuse block and a 6 AWG to battery ground.
What I have tried:

• Using an independent battery not connect to the boat to power controller, sound was there but not amplified to bad.
• I have tried running directly off one of the batteries with the same result of noise while cycling colors.
• Checked and double check the RGB 4 wire on all speaker to ensure nothing is crossed or hooked up incorrectly.

One suggestion is to ground all 3 of my RCAs to the chassis of the radio. Have not tried that yet.
I have 2 batteries, New JVC head Unit, 6 6.5 Enrock speakers, 1 Pyle 400 watt marine AMP & 1 8” sub/AMP running about 15 feet from batteries using 8 AWG for power and ground.
Thoughts???

Would switching to a wifi controller vs RF help? my other set of lights is on a wifi controller and I dont seem to have the issue.

In most all cases it depends on how well shielded the LED's are. Most the items being sold are the lower price ones, so they don't have the same engineering going into the design. Going to wifi puts more signal in the mix and may or may not be better, it all depends on how well they were built

Understood, thank you for the advice!!

***Update***
Added ground loop isolators and that eliminated 98% of the noise. Thanks for the help!!
