The RCAs are for an external amp, one pair for the front, one pair for hte rear and one pair for the subs.

If you don't have an amp, all the white, green, grey, purple wires should be connected to the wiring harness, color matched. Those wires are for the internal amp on the HU.

 

I must have a bad HU because I am going by an 02 diagram and all of the speaker wires are correct. Unless I have something else other than the speaker wires hooked up wrong I don't know. I guess the steering wheel controls are not an issue? P.O.S

 

So you are using an aftermarket stereo harness, like it color matches into the HU? You shouldn't need a car diagram at all.

 

The wires from the truck are totaly different.

does it have the infinity premium sound option? if so you have to hook up the stock amplifiers with the new headunit...do a quick search or even look at the diy installation sticky it'll tell you both ways to fix it

 

I got that. The colors in the truck are crazy colors br/rd db/rd br/lb br/yl db/or ect. Not on the harness yet they are all marked.

 

what is diy? Even if it is the premium I had an alpine head int it. I t got jacked today. I think I got a bad HU. I got power no sound to the Kenwood. Extremely frustrated.

 

All wiring harness are the same colors and matched to color fit CD plyaers perfect. I think your problem lays there. But can't tell you, you lost me, take a pic of the harness/ect.

 

The collors for the adaptor match the radio harness but not harness in the truck.
