Honed Polk perfection

These DB 402 2-way speakers feature a 4" polypropylene woofer cone with a strong rubber surround for solid playback and resilience under the environmental stress that comes with living in your car doors. A 3/4" silk dome tweeter delivers smooth highs with precision to give you a vibrant soundstage, while a built-in crossover keeps the highs and lows flowing to the proper drivers.

For custom installation

Polk includes mounting hardware, along with boldly designed grilles that add flare to your vehicle's interior if you're doing a custom installation.

Product Research

Features

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The DB402's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Please enter your vehicle information to confirm fit.

Marine Certification: Polk speakers are marine certified, making them a good choice for boats in fresh water, convertibles, motorcycles, ATVs, and other applications where the speaker might get wet. Because they have coated steel baskets and the terminals and crossover components are not covered, we do not recommend using them in salt water environments.
