Car speaker set BLOW 30-804 (2.0; 120 W; 165 mm) — 2-way coaxial speakers for vehicles

BLOW 30-804 is a 2-way coaxial car speaker set with a 165 mm (6.5") driver diameter and a rated total power of 120 W. Designed for in-door vehicle audio upgrades, these speakers combine a midrange woofer and an integrated tweeter to deliver clear mid frequencies and articulated high frequencies in a compact installation format. The speakers are intended as direct replacements for many factory units and are suitable for improving speech intelligibility and music detail during everyday driving and longer trips.

Advantages

The 2-way coaxial design provides a single, space-efficient speaker that reproduces both midrange and high frequencies without the need for separate components. A 165 mm driver size balances low-frequency presence and fitment in common vehicle mounting locations. With a rated total power of 120 W, the speakers support higher volume levels and dynamic peaks compared with many stock units, while the integrated tweeter improves high-frequency clarity and instrument separation.

Suitable for

• Replacing factory door or rear deck speakers in passenger cars
• Upgrading sound clarity for podcasts, audiobooks and vocal-forward music
• Improving midrange presence and treble detail for daily driving and road trips
• Use in systems where space is limited and a coaxial solution is preferred

Key specifications

• Driver diameter: 165 mm (6.5")
• Configuration: 2-way coaxial (woofer + integrated tweeter)
• Rated total power: 120 W
• Intended mounting location: in-door or rear deck vehicle installations
• Design focus: balanced midrange with enhanced high-frequency reproduction

How to use

Install the speakers in compatible speaker cutouts in vehicle doors or rear deck following the vehicle manufacturer’s mounting procedure. Disconnect the vehicle battery before beginning installation to avoid electrical shorting. Ensure correct polarity when connecting speaker wires to maintain phase coherence. If necessary, use appropriate mounting adapters or spacers for secure fitment and to avoid interference with door mechanisms. After installation, play a range of audio material at moderate volume to verify correct operation and seating; adjust head unit or amplifier settings to achieve desired tonal balance.

Usage recommendations

For best long-term performance, avoid prolonged high-volume playback at maximum power and verify that speaker surrounds and mounting hardware are secured to prevent rattles. When integrating with aftermarket amplifiers, match amplifier RMS output to speaker specifications and use proper crossovers if separating frequencies further.
