## Long description

BLOW YDQ401 is a 4" coaxial car speaker designed for in-dash or door installations. With a compact 4-inch diameter and 50 W nominal power handling at 8 Ω impedance, this driver provides basic, reliable audio reproduction for factory systems, headunit upgrades or simple replacement of worn speakers. The coaxial design integrates a mid/woofer cone with a centrally mounted tweeter to deliver a balanced single-speaker solution where space is limited.
Advantages
The 4" size and shallow mounting depth allow installation in many factory speaker locations without extensive modification. A nominal 50 W power rating and 8 Ω impedance match common car headunits and basic amplifiers, simplifying integration. The coaxial layout offers improved high-frequency response compared with a single-cone driver, while the compact form factor supports economical replacement or upgrade projects.
Suitable for
 Factory headunit replacement in compact cars
 Door or dash installation where space is limited
 Basic audio system upgrades without external amplification
 Restoration of original equipment audio where matching size and impedance is required
Key specifications
 Speaker diameter: 4 inches (approx. 10 cm)
 Nominal power handling: 50 W
 Impedance: 8 Ω
 Coaxial configuration: integrated tweeter and mid/woofer
 Typical mounting location: dashboard or door panels
How to use
Before installation, disconnect the vehicle battery and verify speaker cutout dimensions and mounting depth. Connect the positive and negative speaker leads to the corresponding terminals on the BLOW YDQ401, observing correct polarity to maintain phase coherence with other speakers. Secure the speaker in the mounting location using the original hardware or appropriate screws, ensuring a flush and vibration-free fit. After installation, test the system at low volume to confirm correct wiring and then gradually increase volume to check for distortion or abnormal noise.
Usage recommendations
For best results, match the speaker to headunits or amplifiers capable of driving 8 Ω loads and avoid exceeding the nominal power rating to prevent damage. If system performance is to be improved, consider adding sound-deadening material around the mounting area and using a basic crossover or equalization to optimise mid and high frequency balance.
