Speaker volume problem
I have a stock head unit with Memphis door speakers and tweeters. When I start the car and turn on the radio the door speakers sound like they are barely audible at about 2 or 3 volume bars on the radio. When I turn it past that to about 4 bars the sound jumps back to normal volume as if I had the "att" button on.
I haven't pulled the speakers or headunit yet to see if the wires are loose. Any suggestions on what it might be? The speakers do have cross overs on them and I also have an amp and sub connected to the head unit but have not had trouble with them.

Is this something new, or has it always done that? If it has always been there, I would suggest it could be due to the logarithmic volume taper used in the digital controls...for cost reasons, the number of possible digital "steps" used in raising/lowering the volume is minimized, but this means poor resolution at low volume levels (i.e., you have to turn it up several notches before the volume really kicks in, and then it's a large jump).

also, you might want to see if the amp is turning on at the lower volumes... just make sure that at 2 bars, the power light is on...
when it jumps up at 4 bars, if you turn it back down to 2 bars, does it drop off to the same levels as earlier, or is it louder than before?

A couple of ideas off the top of my head....
What outputs from the stock head unit are you connecting to the amplifier? Rear channels? Or do you have line converters also connected to the front speaker outputs (not the best idea)?
Does the amplifier have to 'sense' an input to turn itself on? It might be loading down the inputs until it turns on, possibly putting too much of a drain on the head unit and reducing the audible level of your front speakers until it turns on.

jeff,
i was thinking along those same lines as well... check to see when the amp powers up during the process...
hrm....
also, check for any wires that might be touching off to ground as well... it's very faint in my memory, but i seem to recall someone i knew having a problem just like this years ago... i seem to recall his issue was that the speakers were going to a common ground...
this was over 13 years ago, and i was much less versed then -- so my memory could be fuzzy or i might have thought i knew what i was doing and got lucky...
