- Rear Right (+): Purple
- Rear Right (-): Purple with Black Stripe
However, always consult your car stereo’s wiring diagram, as color codes can vary.
Connecting to the Speakers: Your car’s speaker wires may be terminated with connectors or require you to splice them. If using connectors, simply plug the corresponding wires together. If splicing is necessary, use wire connectors (like crimp connectors or wire nuts) to securely join the wires.
Speaker Placement and Considerations: Pay attention to speaker placement. Front speakers are typically in the doors or dashboard, while rear speakers are in the rear doors, rear deck, or cargo area. Consider the direction of the speakers and how the sound will travel throughout the car. For instance, in a hatchback, the rear speakers may need to be angled to project the sound forward.

Ensuring Correct Speaker Wiring Polarity

Polarity is essential for the sound quality. Incorrect polarity causes the speakers to work against each other, leading to reduced bass and a muddy sound.

Understanding Polarity: Polarity refers to the positive (+) and negative (-) terminals of the speaker. When all speakers are wired with the same polarity, the speaker cones move in the same direction, creating a strong, clear sound. If the polarity is reversed on one or more speakers, the cones move in opposite directions, canceling out some of the sound waves.
Checking Polarity: There are several ways to check polarity:
- Visual Inspection: Some speakers have markings (+ and -) on the terminals. Ensure the corresponding wires from the stereo are connected correctly.
- Battery Test: Briefly touch a 1.5V battery to the speaker terminals. If the speaker cone moves outward, the polarity is correct. If the cone moves inward, the polarity is reversed.
- Using a Polarity Tester: A polarity tester emits a specific tone that can help identify the correct polarity.
Consequences of Incorrect Polarity: The impact of incorrect polarity is noticeable, particularly in bass frequencies. You’ll likely experience a loss of bass response and a generally muffled sound.

After connecting the speakers, it’s time to configure the settings. Most Android car stereos offer various audio adjustments to optimize the sound.

Accessing Audio Settings: Navigate to the audio settings menu in your car stereo. This is usually accessible via a button labeled “Audio,” “Sound,” or a similar term.
Adjusting Speaker Balance and Fader: Use the balance and fader controls to adjust the sound distribution. The balance control allows you to shift the sound between the left and right speakers, while the fader control adjusts the sound between the front and rear speakers.
- Balance: If you primarily drive alone, centering the balance ensures that the sound is equal in both the left and right sides.
  
  If you frequently have passengers, consider adjusting the balance slightly towards the driver’s side.
- Fader: Adjusting the fader can be a great way to emphasize the front or rear speakers. If you prefer more sound in the front, move the fader forward. For passengers in the rear, move the fader toward the back.
Equalizer Settings: Use the equalizer to fine-tune the frequency response. This allows you to boost or cut specific frequencies to match your music preferences and the acoustics of your car.
- Presets: Many stereos offer equalizer presets (e.g., “Rock,” “Pop,” “Jazz”) that automatically adjust the frequencies.
- Customization: If you prefer more control, customize the equalizer settings. Boost the bass for a richer sound or cut certain frequencies if you find them too harsh.
Subwoofer Settings (If Applicable): If you have a subwoofer, configure the subwoofer settings, including the crossover frequency and gain. The crossover frequency determines the range of frequencies the subwoofer plays, and the gain adjusts the subwoofer’s volume.
Volume Levels and Source Selection: Ensure that the volume levels are adjusted to your liking and that the source (radio, Bluetooth, etc.) is selected correctly.
