e30 stereo query

[DLMRUN2002@xxxxxxx]

I recently  upgraded  my stereo with sperate woofers and tweeters. I used the  door pillar to mount my new tweeters and  noticed the factory ran the wires for the tweeters even tough my car didn't come with the top end stereo sytem. Does any one know where these tweeters wires will appear on the other end away from the pillar?
Thanks
