I played my car computer system for the first time today and while it sounds very good I am experiencing a loud intermittent turn off pop, it is loud enough that I am worried about the tweeters. This is an active 4-way system and as far as I can determine the grounds are good. I also disconnected the car computer and re-installed the Kenwood 2-din head unit that the car system replaced and with the Kenwood there was no pop.
I am using a Meanwell Dc-DC converter to isolate the car computer from the cars electrical system and there are the usual hot and ground terminals for in and out and there is also a ground that can be connected to the car frame and I'll try that tomorrow but in the mean while I am hoping someone might have suggestions about what might be going on.
Thanks,
