ive connected all the wires exept for a blue one running from the harrness that says is for the anntenna and a nother blue one running from the back of the headunit that says its for remote outout only to amp or remote.... and ive tryed connecting them but it doesnt fix the problem... my back 6 by 9s arent working but my front speakers are...

 

The remote output is for turning on/off an external amplifier. If you don't have one, you shouldnt be using that wire at all.

 

remote is the blue with white stripe. remember that. if u do only blue antenna, your speakers will only work with the radio.
