Harman/Kardon pops when using USB and Iphone

I picked up my 2015 Summit last week, and with sad disappointment, I am not impressed with the H/K sound system. It sounds great on all sources, including when I have my iphone connected via USB.... with one exception. When using the USB connection to listen to audio on my phone, the system pops only from my rear driver's side door from what I can tell. I don't listen to rap, so not heavy bass music, but if I even semi crank it... volume at 3/4 of max, the speakers pop. I would think that for a 825 watt, incredibly expensive sound system that I would not have this problem... these speakers should be able to take a punch.

I have not talked to the dealer yet, but I will when I go in for my first oil change.

Anybody else experienced this?

Greetings,

I would make arrangement with dealer to look at it. You might have a ground loop problem or wire connections that is not right. Over time, this could potential damage the speaker.

Best for now.

Tell the dealer about the problem . My Summit sound system works perfect with my iPhone 5 .I love it ! There must be a short somewhere . Good luck.

Re: Harman/Kardon pops when using USB and Iphone

My 2015 summit is also doing it with my 4th gen iPod plugged into USB. No other sources do it - I figured it was either because I had an old iPod or because I've compressed the music so much. I'm no expert so I don't have a clue.

It could be a short then?

Greetings,

Did you try another USB device and a different USB cable in that same USB port? If nothing happens, then it could be problem with either the first USB device that you had the problem with or that first USB cable. Otherwise, you need to check to see if their is a short.

I have not read many complaints about this problem. Their is also a very remote possibility that their is a bug in the software. With aftermarket Headunits, their are very random occurrence in various different situations similar to yours. So it not that wired. In fact, Pioneer CarPlay NEX unit are experience a similar problem that affects the aftermarket amps and now traced to a software bug.

Best for now.

Re: Harman/Kardon pops when using USB and Iphone

Tried the cable, that didn`t work. Still had the popping sound. Going to try installing music on my ipad and try it soon. There is no EQ on in the iPod settings either. It`s frustrating. The sound from bluetooth connection from my samsung phone works perfectly as well as all radio. Yet to try the SD card slot since I`ve brought it home a few weeks ago.
