I am installing an after-market head unit in my 92 lexus sc400. I am running into a few problems. I have the cd player turned on, so grounded, illumination and power. I cannot not seem to figure how to wire up speakers, all or the diy's do not have what color the speakers are? THe diy's are only to install after-market head unit and use original sub and amp. I am installing new head unit, new amp, and new sub. here is the diy install thread

but it does not lead me to which wires are for speakers, also my new head unit has a ground for each speaker, do i need to ground left rear, left front, right rear, and right front? I would really appreciate if someone could send me a link for wiring diagram for speakers, and if i need to ground each speaker like my new head unit is asking for?
