I was changing the speakers im my jimmy, & noticed the rear door speakers had a resistence of 9.5 ohms each. I also noticed that the connection wire on both rear speakers was the same colour as the front left door yellow & tan. Can somebody confirm this?? I didn't have time to check at the hu the actual resistence. How can I make the resistence proper on the line? Can I just add a resistor in the line to bring it to 4 ohms?

Constant 12V+ Orange
Switched 12V+ Yellow
Ground Black
Illumination Gray
Dimmer Brown
Antenna Right Front
Front Speakers 6 1/2" Doors

Left Front (+) Tan
Left Front (-) Gray

Right Front (+) Light Green
Right Front (-) Dark Green
Rear Speakers 6 1/2" Rear Doors

Left Rear (+) Brown
Left Rear (-) Yellow

Right Rear (+) Dark Blue
Right Rear (-) Light Blue

Hope that helps. Not a Bose system, is it?

I know all the colour codes, I'm concearned about the resistence of that one line & what it'll do to the deck as three speakers are connected to the yellow & brown circuit
