Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Product Research


Woofers: The mineral filled polymer composite woofer cones in this design produce deep clean bass with superior midrange detail. Butyl rubber surrounds are used because of their resistance to harsh elements and improved sound quality.

Tweeters: 3/4" polymer treated silk dome tweeters produce smooth, detailed highs with excellent off-axis response and soundstaging

Midranges: A 1-1/2" poly cone midrange driver is used in this speaker.

Gold plated speaker terminals are used for corrosion resistance.
