HELP 2015 Supra SG 400 issues

[Chiro]

I have a 2015 supra sg 400 with issues. The supra vision and polk audio head freeze up. Supra and dealer have switched all the components out and its still freezing up. This weekend i noticed that when the systems froze up if i opened the compartment door to the polk stereo after a few minutes the system started working again. Sounds like the system is over heating and shutting down. Has anyone else experienced this problem. Any suggestions on how to fix, It doesn't seem like theres much ventilation....

How many remote controls do you have on the boat?
Other locations to remote volume or adjust source?
Mine has three and the one on the transom was causing a problem so we disconnected it and all is well.
Last week, I did lose an amp for about 20 min as it shut down due to heat.
I have one Kicker amp and one Polk amp. Both are extremely hot to the touch after
awhile. I hope to replace most of stereo in the off season.
