Thanks for the clear advice! I like your idea of separate spaces into one enclosure. I'll do some testing with that and the use of one or more filters. To be continued...

Thanks so much for this post and for hitting the Made It button! Great to hear that the I'ble was useful for you!Y.

It might be overheating. The chip-amps turn off when overheated. Your heatsink seems large enough though. Is it hot just after the sound turns off? Is your case perforated, so that hot air around the heatsink can flow out?

Wonderful! Great build, thanks for the post. Posts like these always make my day :)Y.

You can make one for yourself with this Instructable ;)

Pretty rings, great I'ble. As ever...
