i know the tweeter doesn't get its signal from the mid driver wire (no inline crossover from the front mid to tweeter).

any help is appreciated. also, does anyone know where the subwoofer and front mid is crossed over at? thanks.
.. I think "keyword - think" that what you're finding is the tweet signal is split off, generated by the amp. So the tweets have their separate lines from the amp, rather than sharing a channel with the door mids. This is a good thing, called "running active tweeters". However, it requires extra amp channels to do so and crossovers that will split off only tweeter range high-pass to the tweets and typically band-pass to the mids (below the tweets, and above the sub).

Not to confuse too much but basically if I understand how these premium sound Si's run, there's just four channels to the oem amp from head unit (standard garden variety front/rear left/right), then those are split into seven from the oem amp (2 tweets, 2 mids, 2 rears, 1 sub).

I'd be glad to try to pull this into visio and draw this diagram up and post it to see if I'm correct with colors, etc.. I think it might help us all.. I just need to verify the pinouts and colors. Don't know also if there's differences from year to year with these premium sound setups.
