Question for all first gen Audio owners; in my stock system, sometimes where I turn it on the left or drivers side seems a bit weaker than the right side at the same volume level. This is for both the front and the rear speakers on the left side. As it warms up it mostly goes away so that they sound just fine. A bit about this first gen stereo. The rears go through a dedicated amp and the fronts run directly from the head unit. My since both the front and the rear on the same side seem to be having a problem my thoughts are that I might have a bad solder on just the one side in the main head unit that is putting out the sound. As it warms up the solder joint expands making a better connection; thus the sounds comes back. Any ideas on this?
