Hello,
I am in the process of upgrading the sounds system in my truck and have came across some problems. I no longer have sound.
I installed Polk audio speakers in the doors and rear no problem. Then came the head unit, this is where my problem lies. I know the speakers are hooked up correctly because they work off the old factory head unit. Now I also found out my truck has a factory amp.
I used a scosche wire harness the, FDK106, and wired it properly according to the instruction of to the new Sony head unit I bought.
After wiring it correctly I found I had no sound. Now I was wondering can I open up the “blue cable” the one that contains the cables that went into the old head unit and match up the correct polarities.
After much research I found the exact wire diagram of the amp
“Blue cable” output of original head unit and input to amp
Purple/White Stripe RR (+)
Light Blue RR (-)
White/Red Stripe RF (+)
Brown RF (-)
Light Blue/Black LR (+)
Yellow LR (-)
Light Green LF (+)
White/Orange Stripe LF (-)
Main Harness (output of amp to speakers)
Black/White Stripe RR (+)
Orange/Red Stripe RR (-)
Dark Green/Orange Stripe RF (+)
White/Light Green Stripe RF (-)
Tan/Yellow Stripe LR (+)
Pink/Light Green Stripe LR (-)
Light Blue/White Stripe LF (+)
Orange/Light Green Stripe LF (-)
Will splicing according to polarity work? Or is there another set of speaker wires I can use?
Thank
