PowerBass
4 x 6 inch coaxial speakers designed for direct OEM replacement with zero-protrusion tweeter
PowerBass S-4602 coaxial speakers are built to replace factory units in 4" x 6" openings without modification. The zero-protrusion tweeter design clears tight door panels and dash locations across many vehicle makes. Drivers who want better sound than stock but need a direct fit will find these match the original mounting pattern exactly.
Coaxial car speakers are passive components that draw no power and generate no heat on their own. The amplifier or head unit supplies the signal and handles all thermal load. In normal use the cones and voice coils run at ambient temperature and add no audible noise to the cabin.
These speakers accept standard speaker wire and require no crossovers, enclosures or external power. They free up installation time because they mount directly into the existing 4" x 6" cut-outs. Builders who need a different size or a component system with separate tweeters will need to look elsewhere.

Mount the speakers in the factory 4x6 openings using the included hardware, then connect the wiring harness; the step often missed is verifying the tweeter sits flush for the zero-protrusion fit.
The proprietary 2-layer paper cones with DDC may eventually need replacement if the surrounds deteriorate from moisture or UV exposure; the tweeters are built into the coaxial assembly and are not separately serviceable.
The 2-layer paper cones can reach their thermal and excursion limits first, causing compression or distortion before the tweeter or crossover components show stress.
