Car stereos and receivers, also known as head units, are built with four channels of output for powering two front and two rear car speakers. When installing an Android car stereo for BMW, it’s necessary to connect the car’s speaker wires to the head unit with some simple tools and connectors.
Things You’ll Need
- Wire strippers
- Crimp tool
- Butt connectors
Instruction
- Use a wire stripper to remove 1/2 inch of insulation from the ends of each of the BMW head unit‘s speaker wires and from the ends of the wires leading to your car speakers.
- Match the output wires of the head unit to the speaker wires they’ll be driving. Head units follow a set pattern of color coding across all brands — the front left speaker is powered by the white and white/black wire, front right by gray and gray/black, rear left by green and green/black, and rear right by violet and violet/black. Car speaker wiring varies by model and brand of car. If in doubt, look up the speaker-wire codes in a service manual, such as a Chilton’s Auto Repair Manual, available at auto-parts stores, bookstores and online.
- Slide the bare end of a head-unit wire into one end of a butt connector. Slide the matching car speaker wire into the other end. The butt connector is a common wire-crimping connector that resembles a small, hollow plastic-covered tube open on each end. Place the jaws of a crimp tool in the center of the connector and squeeze the handles of the tool to make the connection. Repeat for all the wires.

How to Install an Android Car StereoFirst, turn off the electricity to the machine by removing the live battery wire from its station. After disconnecting the battery, you’ll need to take off the trim boards enveloping your car stereo. Each car just a tiny bit unique here. Next, you need to dispatch the previous head unit directly out until the wires connected to the back are accessible. Unplug the cord, discharge the cabling harness and proceed to remove the antenna cable by unscrewing it. The cabling harness is the structural fastener that integrates all of the cabling for the sound system into an individual connection. The new head unit you have purchased should have included an adapter that matched the factory installed cabling. The end of the cabling on the end, should have four to eight colored wires coming from the back. There should be two such wires that plug to each speaker; one positive one negative. Most negatives are shown with a black stripe while positives are generally either solids or have a white stripe. If your new car DVD player does not come with an adapter that works with the harness in the dash, you need to purchase a cabling harness kit. The new harness will have to be plugged into the new stereo. Match the colored wire to its match and put them together. After having the wires connected to their proper match, the stereo should be ready to install. Hold the system to the dash to plug the proper connections into the back.
