## Long description

The Peiying PY-AQ402C is a 4" coaxial car audio speaker designed for in-vehicle use as a replacement or upgrade for small factory speakers. Its compact coaxial design integrates a full-range driver with a tweeter to deliver clearer midrange and improved high-frequency detail from a single mounting point. The speaker is intended for door panels, rear decks or other standard small cutouts, providing a practical option for restoring or enhancing clarity in automotive audio systems without extensive modification.
Advantages
The speaker offers a compact footprint that fits common small speaker openings while combining midrange and treble reproduction in one unit, which simplifies installation. Its coaxial configuration reduces the need for external crossovers and maintains phase coherence between the driver and tweeter. The design focuses on clarity and intelligibility of vocals and instruments in the mid and high bands, making it suitable for system-level upgrades where space is limited.
Suitable for
Replacement of worn or damaged 4" factory door or rear deck speakers
Basic upgrades in budget or entry-level car audio systems
Compact installations where a single coaxial speaker is preferred
Applications requiring improved mid/high frequency clarity
Key specifications
Driver diameter: 4 inches (approx. 100 mm)
Coaxial design with integrated tweeter for full-range reproduction
Intended mounting: standard small automotive speaker cutouts (door panels, rear deck)
Suitable power handling for typical factory and aftermarket head units and modest amplifiers
Compact frame for tight installation spaces
How to use
Install the speaker into a compatible 4" mounting location using the original screws or supplied hardware where applicable. Ensure correct polarity when connecting the speaker to the vehicle wiring to maintain proper phase and stereo imaging. If the original cutout or mounting depth differs, use an appropriate adapter or spacer to secure a stable fit. Avoid exposure to direct water ingress and secure wiring to prevent chafing during vehicle operation.
Usage recommendations
For best performance, pair the speaker with a properly tuned factory or aftermarket head unit and check polarity during installation. If higher output or deeper bass is required, consider adding a dedicated woofer or an amplifier matched to the vehicle's acoustic environment. Use appropriate mounting adapters or foam gaskets to reduce vibration and ensure a sealed installation where possible.
