Speaker sound problem

I've did my research around the forum here and audizine, but can't really find an answer...

It's around 30~35 in the morning when I start up my car and the right front door bose speaker is doing this distorted/hissing sound, but when the day gets to around 70+ (or basically warms up) in the afternoon the speaker would sound clear and normal again.  Anyone has any solution to this problem? I have replace the speaker (to a working bose speaker) too myself but the problem still stays.  Seems like the speaker itself is not the problem but somewhere else and is affected by the variation in temperature.  Would like to get some opinions before I go in and pull out the headunits and such to see if there's anything else there.  Thanks in advance!

im not an expert. But i suspect a faulty wire(s)/plug.
 
I would change the wires and see if that makes any differences. We have cheap wires in our cars.

my question is, which part of the wirings/plug should I look into? the ones connected to the speaker or to the headunit? and where can I obtain those wiring parts?

which system do you have? i'd take a look at the speaker itself first.

I think he has a bose system. If we assume that he has a good working speaker, the problem should be in the plug/wires connected to the speaker.
 
Since when do you have this problem? When did this start? 

haha duh how did i miss that lmao. well i'd check the amp too since you have the bose

lol.. yeah I have a bose system, with Concert headunit, (1999.0 A4 1.8TQ tiptronic). 

And yes. the speakers are working properly cuz I've swapped in a good working speaker (tested) and it sounds just perfectly fine when it was warm.  But early in the morning when it's like 35 it'd be making all those noise (just that one frigin speaker too!).  Aiight, i'll see if swapping in the extra amp would solve the problem.

oh and I baught the car back in January ( lexus sc300 was totalled cuz some 94 years old lady smashed into my rear wheel And i wasn't in town, cousin was dealing with it) Cousin picked up the car for me, and unfortunately he didn't notice that problem at all. yes, sux, I know.

trust me, the speaker is a lesser problem you're dealing with compared to some of the problems others have had to deal with lol

was just on the road, and it's 68 outside.. everything's warm up and all, and yes. the speaker works PERFECTLY... i even direct all the output to the right front passenger speaker (the one that acts up).. nothing, crystal clear.  How weird is that?!

to hiwords: i believe ya.. i only wish i have the money to go in and do some performance mods like the gurus up here... :P or heck.. have a grand to throw around for a set of new sound system would be nice!

this happens on my system too... i have the bose setup, and my front passenger speaker acts the same way when its cold here (CO mornings mostly)... I run a fm transmitter for my zune, so i had been ignoring it thinking that it was probably just interference, but i would definitley be curious if you find out what is wrong/how to fix it

I have the same problem with my bose system. I suspect wiring too, because when it is cold some of the pixels in the display screen don't work. It's weird because as soon as it warms up they work perfectly.

Just swapped an extra working bose amp with my old bose amp, problem is still there... so I guess I'll be checking WTF is going on with the wires/plugs... GRRRRRRRRRRRRR

chances are that channel in the radio itself is going bad. had the same problem in a customer car, swaped the radio and no more snap crackel pop. check the ez stuff first

GREAT.... more reasons to buy a brand new HU.. lol
