Value and performance
If you're looking to upgrade from your factory speakers, MTX designed their Thunder Dome series speakers for efficiency, so they'll give you plenty of performance even when powered by your factory stereo. And MTX made sure that all these speakers deliver extended bass response, from the modest 3-1/2" to the big bruiser of a 6x9". Best of all, they're covered by MTX's unique 5-year warranty.
Bigger, fuller sound
The Thunder Dome Series TDX40 4" 2-way speakers deliver a surprisingly full sound, courtesy of a polypropylene woofer cone with a butyl rubber surround. The 1" silk tweeter uses a dome design to improve high-frequency dispersion through your vehicle, bringing out details you might otherwise miss. These speakers handle up to 35 watts RMS, so you crank the tunes up and still get clean sound. Grilles are not included — factory grilles are appropriate for most installations.
