Im installing a JVC KD - A315 radio in a 2003 alero, when i took out old radio all the wires were cut and turned into speaker wire running all over the place the factory amp is in the back i went ahead...


There may be extra wires you don't need. The basic set of wires on the radio is 4 pairs of colored wires--one black-striped and one plain for each speaker. Yellow is usually accessory power, red is hot, and black is ground. Some additional wires may be one for a power antenna, one for an external amplifyer, and one for facelight (in case it will run on dimmer)
The car should have the following corresponding wires:
Radio 12v--- orange
Radio Ground--- black
Radio Ignition--- yellow
Radio Illumination--- brown
Dimmer--- gray
Power Antenna--- pink (if you have one)
LF Speaker +/- tan - grey
RF Speaker +/- lt green - dk green
LR Speaker +/- brown - yellow
RR Speaker +/- dk. blue- lt. blue

The car or radio could have additional connectors, such as for a subwoofer, CD changer, etc.

I cant get power is my harness missing wires?


Yes, your red wire is for ignition, yellow wire is for battery and black is ground. The red ignition wire is for the radio to turn off and on with the ignition. The yellow is always hot, for memory.

I need to know what colors mean what, so i can hook my cd player up


Red - Power
Yellow - primary power must be joined to the red
blue - Remote
Black - ground or negative
To find your speaker wires check the color of the cord behind each speaker than match it with the same color in the dash.
or the easy way is to use a normal 1.5v penlight battery and try each speaker cord behind the dash and listen to which speaker give off a crackling noise so you can get the balance on the cd player right.
If u trying to find power in the car and don't have a tester than get a 12v light or bulb join the negative to the body and push the positive wire into each one of the holes in the factory plug in the dash one at a time until the light comes on. That is your positive the rest is easy. (DIY guru)

Blue White: Power antenna up/down

Grey: Right Speaker POSITIVE (+)
Grey Black: Right Speaker NEGATIVE(-)
