To answer your question, the yellow wire. That's main power to the head unit. But....<font face="Verdana, Arial" size="2">Originally posted by a_wlee:
after picking up engine noise with my Pioneer 1695's I have been told to add in one of those inline filters to the stereo, can anyone tell me which wire it should be connected to in the back of the stereo.
Only the speakers were changed!!<font face="Verdana, Arial" size="2">Originally posted by shindog:

If you have JUST a factory head unit, you should take it back to the dealer; they should replace the radio and/or troubleshoot your problem. Just replacing speakers should not result in noise problems.
If you went aftermarket, may I ask what else you have installed besides speakers? Factory head unit with outboard amp? Just a new head unit? Aftermarket head unit and amp? What make/brand? My experience is that most problems are the result of ground loops.
If you want more help troubleshooting your noise problem here, I'm glad to help, just give me more info on your system.
