Dynavin V5 - noise from speakers at idle

Hi there. I have a Dynavin V5 and recently I have noticed a soft high pitched noise from the front tweeters in the door when the engine is at idle.

The pitch does increase with the engine revs but becomes inaudible at higher revs. When it idles again, the high pitch noise returns.

I don't recall this noise being there before up until recently (probably in the past couple of weeks).

What could cause this and how can I resolve this issue? Why would it only start occurring recently?

Thanks for any advice anyone can offer...coz it's driving me nuts

could be alternator noise, long ago you could fix that with a capacitor on the "+" pole at the alternator, but with modern cars it shouldn't happen,just a thought,maybe all those spare connectors hanging out the back of the dynavin,did you wrap insulating tape around them separate them from the power connector?,cos if one is close to power feed or touching a metal part you could have an inductance thing happening,which could be the source of your problem.

I was thinking about that just now, actually. I had previously ripped out the Dynavin in an attempt to get my steering wheel controls working, and then stuffed all the cabling back in when I put it all back together. So it's quite likely this caused it to happen. I'll rip it out again and tape the loose ends up and isolate from the power connector and metal parts. Wish me luck. Thanks for your advice!

This happens with my DICE that is a plug n play with my CD changer wireing. Thoughts on that one? Weird...

When i'm idling, its actually a loud(er) buzzing/ticking noice, and then when i am driving, you can hear the alternator noise that increases in pitch when my revs go up. Need to troubleshoot that one

I just have no clue why it would do this is if its plugged into an OEM wire...

Consider luck "wished", you seem to have had your share of problems with the dynavin install is it all sorted now?

I havent had time to rip it out again yet to address the noise on idle, but will do so this week. As for the steering controls, no, not working yet. I havent gotten around to ordering a fakra cable yet either and even if I have one I dont know how to put it in correctly...
