Aftermarket Car Stereo Wire Colors Guide

Aftermarket stereo wire colors are different than the stock vehicle wiring because there are many aftermarket brands, not just one.

Aftermarket car stereos offer much more than just playing music to your vehicle; they provide you with AM/FM radio, CD players, MP3 music, GPS navigation systems, satellite radio, USB hookups for your iPod or other devices, Bluetooth hands-free calling and connections for Android smartphones to name a few. But every system is different depending on what you want it to do or include.

Aftermarket car stereo wire colors are not always the same as stock wire colors because each manufacturer has their own color-code for their systems.

Aftermarket wire colors are not universal; you will need your stereo’s wiring diagram to know what each wire does and where it is located in the vehicle.

Car Stereo Wire Colors

Wiring diagrams of aftermarket car stereos show all of the required wires needed to provide power, sound, connection for external devices and speakers to name a few. Aftermarket wire colors are normally shown on the diagram by number.

The more wires you have, the more functions your aftermarket stereo will have. Aftermarket car stereo wire colors match up with the color of the plastic connectors on both ends of each wire no matter what the brand or type of car stereo.

Stock wire colors normally include power, ground, speakers and remote turn on (for amps). Aftermarket wire colors can also include USB connections for MP3 players or other devices. Aftermarket wire color codes are not universal no matter what brand is installed in your vehicle.

What Color Wires Go Together In A Car Stereo?

There are four color wire you will see while wiring a car stereo. These colors are as follows: Yellow, Orange, Red and Black. The Aftermarket wiring car stereo color codes are not standard wire code that comes from the factory.

Ground Wire:

The ground wire is typically the color Green or Black. The Yellow/Green wire is common to use as a Ground wire because it will not cause any noise in the radio station like the other grounds would do.

Power Wire:

Blue is commonly used for your power wire on most aftermarket car stereo systems. It is also possible that your power wire may be Red in color.

Speaker Wire:

The wire that has a grey stripe is the positive wire (+) for the speaker on the right. The wire with a black stripe is the negative (-) for the same speaker.

The white wires go to the left front speaker, purple goes to the right rear speaker, and green is for the left rear speaker.

The speaker wires are common to be either White or Black, but it is also possible that the color may vary depending on manufacturer and personal preference.

Antenna Wire:

The antenna wires are commonly Blue or Black in color. This does change between different makes of aftermarket car stereos. Always check the color coding of the input wires and output wires to make sure they match up when wiring your car stereo.
