BOSS Audio Systems 5.25" Car Door Speaker BRS52

The BOSS Audio Systems BRS52 is a 5.25-inch replacement car door speaker delivering up to 60 watts peak power with a polypropylene cone and foam surround for clear, reliable in-car sound.

Designed as a direct-fit replacement or upgrade for factory speakers, the BRS52 balances compact mounting dimensions with audio components built to reproduce midrange and upper-bass frequencies cleanly. With a stamped basket and 0.77" voice coil, this 4-ohm driver fits many standard 5.2" mounting openings and pairs well with OEM head units or aftermarket amplifiers. It’s sold individually so you can replace one worn speaker or assemble a custom set.

How does the BRS52 improve my car’s everyday listening?

The BRS52 focuses on accurate midrange reproduction and controlled low-end for better vocal clarity and fuller instrument tone compared with aged factory speakers. Its polypropylene cone resists moisture and keeps response consistent across temperature changes, while the foam surround provides responsive cone motion.

• Frequency response: 100 Hz–18 kHz for clear mids and highs
• Sensitivity: 82 dB at 1 W/1 m for efficient output with stock radios
• Polypropylene cone and foam surround for durability and balanced tone

Will the BRS52 fit my vehicle’s door opening and depth?

The physical dimensions are compact to fit most 5.25" factory openings: a 4.8" mounting hole and a 1.94" mounting depth. Its lightweight 0.88 lb construction and stamped basket make it suitable for many door or kick-panel locations without major modifications.

• Overall dimensions: 5.20 x 5.20 x 2 inches
• Mounting depth: 1.94 inches to clear door hardware
• Mounting hole requirement: 4.8 inches for secure fit

What power and electrical specs should I expect?

The BRS52 has a 4-ohm impedance and 60 watts maximum power handling, making it compatible with most aftermarket head units and modest amplifiers. The 0.77" voice coil helps manage thermal load and maintain stable performance at highway volumes.

• Impedance: 4 ohms — standard for car audio systems
• Power handling: 60 watts peak for transient headroom
• 0.77" voice coil supports consistent thermal performance

How durable is the BRS52 for daily automotive use?

Materials were chosen to withstand the automotive environment: the polypropylene cone resists humidity, the foam surround allows flexible cone excursion, and the stamped basket minimizes weight while supporting the motor assembly. BOSS Audio Systems backs this product with a robust online warranty for added peace of mind.

• Resistant cone material suitable for varying climates
• Stamped basket for corrosion-resistant structural support
• 3-year platinum online dealer warranty from BOSS Audio Systems

Who is this for: The BOSS Audio BRS52 is ideal for drivers who want an affordable, reliable replacement for worn factory 5.25-inch speakers or a budget-conscious upgrade to improve vocal and midrange clarity. It suits vehicles with limited mounting depth, DIY installers comfortable with basic car speaker installation, and owners who prefer to pair stock head units with efficient, 4-ohm speakers. For optimal results and safety, BOSS strongly recommends professional installation.
