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

https://www.clublexus.com/forums/lex...b-working.html

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?

 

never mind i bypassed stock amp and messed around.. hehe got my bump bump now

 

Did you figure it out? I have a thread on this in the gs section. Really easy.

 

can you send me the thread please going thru it with my daughters gs300
