Im looking for the radio wiring diagram for 2001 pontiac grand am gt1 with the monsoon stereo. I'm putting in some new rear 6x9's and going crazy trying to figure out how to wire them. thanks for any help

Welcome to AF !

its hard to find a good radio diagram,
the ALLDIY or Chiltons online guides are not bad.

Its not that difficult to swap out the speakers.
You will probly hav more truobles installing the 6x9 speakers themselves.

thiers 4 wires on each speaker, two go to the main speaker and the others goto the tweeter.
The wires should be marked + and - on the speakers, not on the wire.
I hav this crapy typical radio diag (http://i28.photobucket.com/albums/c242/xeroinfinity/SeCond%20Hand/99-01radiodaig.png), I'll See if I can find a better one, we need it.

Hope that helps!
