    Ok this one got me confused. Yesteday I got in the truck for work and left speaker had no audio in door except the tweeter. doesn't cut in or out, no popping or crackling like a blown speaker would do. I left work and got in truck and the speaker was working fine. :no:

    So I thought ok maybe I will keep an eye on it. got in the truck this morning and again no sound as if someone unplugged the speaker. Tweeter still going during all this.
    I have read others having this issue with no resolution. Some have replaced the head unit and still having problems. Seen speakers replaced and yet still a problem.

    Any Ideas? anyone no a real solution to what seems to be somewhat common problem?

    Maybe its just a connection to the speaker, try taking your door panel off and checking the wires.

    I noticed one thing so far.

    It seems to only be a problem in the morning when it's cooler. I will post more on what I find when I get it fixed. Gonna get a new voltage meter since the one I have is unreliable and check the voltage at the speaker when it's occurring. This should tell me if it's the speaker or not at least. Then I will have to pin it down to the radio or wiring.

    dudeee, I have the exact same problem. usually occurs in the AM and after i get in my truck after work the speaker works fine..its been freaking me out. please keep us updated on what you find...do u have factory speakers or aftermarket? i have factory and just think it could be because they are so old and ****ty.

    Yeah I have factory. We bought the truck last fall and havn't really changed anything on it. From past experience I have never seen temperatures effect the function of a speaker, but I have seen it effect electronics. But it usually reacts just the opposite with electronics, works when cold and stops when warming up..... I get a meter today so I have it on hand.

    Solved..!!! Just change the speaker!!

    ..... from kvert......
    " ... Yes sorry I should of posted it. Replace the speaker... This is the first time I have ever seen a speaker react this way. I was able to monitor the signal feed to the speaker when it occurred and found that the signal had not changed. I plugged in another temporary spare speaker I had from my stereo system to find that it worked. So I went and bought replacements for both doors and have no more issues. plus it sounds better. lol... "

    Thank you very much!

    It could be a few different things. Alot of times the speaker wire wears in the door boot. It could be partially broken and when you open and close the door it may connect it momentarily until you open it again. Just open and shut the doors a few times and see if it goes on and off for that the brett solution is just to run some new speaker wire. Another possibilty is the speaker is blown. The voice coil can seperate from the speaker and alot of times it will work at some point and then not. You can test the speaker for resistance and if its a stock speaker it should be around 4 ohm. Or if you have a amplified stock system like bose the channel on the amp can be going out. But if you really want to figure it out start by taking off the door panel which is cake and shouldn't take more than a few minutes and bench test the speaker. If it is bose its a little more complicated to fix or replace so hopefully its not.

    Ok I need help here also. When the inside of my truck is below 50 degrees somtimes higher, none of the speakers work at all not even the tweeters. They just make a consistant poping noise even with the key off and the doors open. After it warms up they work great until the truck gets cold again. All the wires are hooked up tight and fuses are fine, I just cant figure it out and it is really annoying if it doesnt get above 30 degrees out side. If you have any info please let me know. I dont think It is the speakers that are bad because they all do it at the same exact time. Oh I forgot its the bose 6 speaker. Any help will be great!
