Hear it goes...
preouts are measured from 20hz-20k hz, manufactures use the highest peak voltage of preout voltage as their rating. For example 2 volts @ 400hz. If you look in the back of every manual Panasonic, Sony whatever, it will have its highest rating @ xx hz. But they do not tell you that at 100 hz it might be .5 volts! That is why you hear a difference, you might have a mid-bass hole in your system because a head unit might only have .1 volts at 400 hz. While a different brand might have 2 volts at 400hz...hence making it some better. Some companies like Eclipse rate their preouts from 20hz-20k hz instead of only one frencency. Eclipse has always sounded better because of this, no other manufacturer will state their rating from 20hz - 20k hz. That is why preout voltage is better, but not all preout voltage is the same. My opinion (which I have tested)
1 - eclipse
2 - pioneer
3 - JVC
4 - Alpine (3 years or older will places them in second)
4 - Sony
5 - Panasonic (the absolute worst in the sub range!)
This is all I have tested...
Or
Add the good quailty line-driver and solve all the issues. Keep in mind some amps cannot take a high voltage preout in...but that is another topic.
Cheers!

the line drive is what i would do

Well i guess the panasonic to eclipse swap was a good one then. Thanks theif! And the gains were changed when it was done, and the difference i heard was not only SQ but i would get chirping at high volumes on the panisonic, but the eclips greatly surpasses the volume it used to chirp at, loud and clear. Thanks!

Another fine example that head unit brand makes a big difference. BTW, my last deck was Eclipse 8445, and I hated it, now I am back to Alpine, and could not be happier. To each their own. My second option is always Pioneer. Alpine and Pioneer sound completely different - sounds like Pioneer has more midbass, and Alpine is treblier. My Eclipse did not have much midrange at all.
