I need to know what color are the speaker cables of a chevy impala 2003. Because I put a new stereo and cut the wires. thank you very much for your help I appreciate it

There are 4 different types of radios for that year. You will have to check which style you have by the RPO code for that vehicle. In the glove box, or the center console or in the trunk (on the panel that covers the spare tire) there should be a placard with all the RPO codes for your vehicle. 3 of the radios, all the speaker wires are the same. It will be codes WX7, U62 or UW6. If you have any of these the wires are:

L/F - Gray (-) Tan (+), R/F - Dk Grn (-) Lt Grn (+), L/R - Yel (-) Brn (+), R/R - Lt Blu (-) Dk Blu (+)

If you have RPO code UQ3 the wires are:

L/F Tweeter - Yel (-) Blk (+), R/F Tweeter - Ppl (-) Lt Grn (+)
L/F - Lt Grn/Blk (-) Dk Blu (+) R/F - Lt Blu/Blk (-) Dk Grn/Wht (+)
L/R - Wht (-) Tan (+) R/R - Red (-) Tan (+)

On a 2003 chevy impala is it ok to replace the factory stereo with an aftermarket cd player even with the security feature?

Yes it is, the security feature on the radio is just for the radio itself. You may also be able to find a used factory CD stereo for the car fairly cheap on ebay.

Replacing 3 pin plug on block heater cable 2003 impala ls. what wires go clor wise into plug

i think you are they should be color coded and match up directly .....however if you changed the wires completely they i would suggest find another 2003 Impala and either photograph it or write the sequence down a dealership will allow you to look at the motor even if you have to pretend you want to test drive it or just look it over

Which color wires go together in a 2002 chevy impala stereo to make it turn on?

If its an aftermarket stereo, the Yellow wire will be 12v all the time. Red is when ignition is turned on, and black is ground. The rest are speaker wires. Mike. Rate 100% please.
