    Icon33 Static/crackling sound from speakers at mid-volume

    I have been getting these noises since installing the new system. I'm using the factory harness to connect speakers and power. I added an extra ground for speakers to the chassis. To date, I have been unable to turn the volume up very high without getting this noise no matter what the media source. However AM seems less problematic than FM, USB and CD but still cannot turn volume beyond low listening level.

    Any thoughts?

    Why are your speakers grounded to the chasis? I have only seen one radio in my life which had a positive going to each speaker, then at the negatives coming back to the deck, required them to be grounded. It was a $20 radio a budy bought at advanced auto parts, I shuttered putting it in for him. It was the crappiest cassete deck in the world, didn't have a rewind button, I doubt a radio like yours with a USB port would ground the speakers to chasis!

    x2 your speakers shouldn't be grounded to the chassis.

    Re: Static/crackling sound from speakers at mid-volume

    Well actually it did not change my problem, but I think you pointed out something I didn't mean to say; I meant to say I added a ground to the existing power ground connection, to another point on the chassis. The Kenwood power ground wire goes into the factory harness, and I wasn't sure if it was sufficient. Apparently it was and is not my problem.

    check to make sure your speakers/speaker wire are not grounded out

    Re: Static/crackling sound from speakers at mid-volume

    Uhm, one time this mexican in a van had noise when his volume got to a certain point. Turned out he used those wire twist caps for home 120V electric connection to conect his wires together. After he redid the connections with crimp connecters, the noise went away. I asked a proffesional why it made noise past the volume limit and he said because the connection was probably so bad that the current demand of the deck couldent pass through the weak connection, so the deck was starved of power and made distortion of some kind. Never really understood it myself.

    Re: Static/crackling sound from speakers at mid-volume

    Well, there was no wiring harness adapter for my car because of its age. So I found some narrow blade-style male crimp connectors that would slide into the factory female harness plug. For the speakers I used standard blade-style male crimp connectors to plug into the factory female harness plug and soldered the other end to the speaker terminals.

    if you had a dmm you can check continuity to ground among the speaker wires.. etc.

    Re: Static/crackling sound from speakers at mid-volume

    I will also be changing my rear speakers from 6822cf to 6812cf, because the factory box was incorrect marked 4 ohm. However, the problem existed prior to installing these speakers.

    You know I have never had this problem before, and it's quite frustrating. This system may not be audiophile quality, but it isn't junk either and it should work.
