Choose the Power Source

1. Choose an AC or DC power source

Car stereos can use either AC (alternating current) or DC (direct current) power. AC power sources are more common in homes, while DC power sources are found in vehicles. You’ll need to know the voltage of the power source you’re using, since car stereos are typically designed to operate within a certain voltage range. AC power sources have a standard voltage of 120V, while DC power sources typically have a voltage of 12V or 24V.

2. Select the appropriate power adapter

If you’re using an AC power source, you’ll need a power adapter that converts the AC power to DC power. If you’re using a DC power source, you may not need a power adapter. The type of power adapter you need will depend on the voltage of the power source and the voltage requirements of the car stereo.

3. Wire the power source to the car stereo

Once you have selected an appropriate power source and power adapter, you’ll need to wire the power source to the car stereo. The wiring instructions will vary depending on the specific car stereo you have, but in general, you’ll need to connect the positive terminal of the power source to the positive terminal of the car stereo, and the negative terminal of the power source to the negative terminal of the car stereo.

Connect the Speakers

Once the receiver and head unit are connected, it’s time to connect the speakers. If you’re using the stock speakers that came with your car, you can simply use the supplied wiring harness. Otherwise, you’ll need to purchase an aftermarket wiring harness that’s compatible with your speakers.

To connect the speakers, follow these steps:

Identify the positive and negative terminals on your speakers. The positive terminal is usually marked with a red ring or a plus sign (+), while the negative terminal is usually marked with a black ring or a minus sign (-).
Connect the positive terminal on the speaker to the positive terminal on the wiring harness. Use the supplied crimp connectors or solder the connection.
Connect the negative terminal on the speaker to the negative terminal on the wiring harness. Again, use the supplied crimp connectors or solder the connection.
Repeat steps 1-3 for all of the speakers in your car.
Once all of the speakers are connected, double-check your connections to make sure they are all secure.
Turn on your car stereo and enjoy the music!

6.5 inches	50-100 watts
8 inches	75-150 watts
10 inches	100-200 watts
12 inches	150-300 watts

Ground the Wiring

6. Ground the Negative Terminal

The goal of grounding the negative terminal is to create a complete circuit for the electrical current to flow. Improper grounding can lead to electrical issues, noise, and even damage to your equipment. To ground the negative terminal, connect a wire from the negative terminal of the stereo to a metal surface on the vehicle’s body or chassis. Make sure the metal surface is clean and free of paint or rust. You can use a bolt or screw to secure the wire to the metal.

For further clarification, refer to the table below:
