Intermittent sub woofer

[Rolly]

My2015, subwoofer runs for approx twenty minutes and then gives up the ghost.
I'm thinking it may be a heat buildup kind of thing, has anyone else experienced this in the Defender 110?
Already done a search and nothing revealed.

Check the connect under the vehicle is making good contact.

Try to eliminate a few variables i.e. is it heat, movement, voltage etc..

Fully charge the battery.
Then turn the woofer on, dont start the car.
Play AC/DC for 30 mins - did it turn off?
Wait 1 min
Play AC/DC again after 10 mins - did it turn off?
Try Beach Boys or Barry Manilow,. did the timings change? :)
If all ok, do the same whilst moving, but dont come near my joint with Barry playing.

Thanks folks, I'll give both of those a burl.
