Product Research
Features
Woofer: The polypropylene cone and butyl rubber surround are resistant to the temperature extremes and humidity often found in the automotive environment, adding to the speaker's reliability and longevity.
Tweeter: Each speaker features a 20mm inverted dome Mylar tweeter for crisp highs.
4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The RCX-100's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please enter your vehicle information to confirm fit.

Not going for super high end - these provide excellent sound. Very happy with these in place of the factory set. Old truck with lots of background noise (1989 Isuzu Trooper) - these do a great job pushing through.
