MTX Audio THUNDER681

The MTX Audio Thunder Series Speakers will improve any stock stereo. Providing a rich full range to your car audio system, you won't miss any part of the frequency spectrum when listening to your music. The midwoofer has an extended low frequency range that will give you great bass reproduction even without a subwoofer. The tweeter can be mounted anywhere and give crisp and clear highs. With over 40 years of audio experience, MTX Audio makes sure and knows how to create quality audio in their products, and the Thunder Series is no exception!

Of course adding a subwoofer to your system will give you fantastic bass reproduction in your system, but with the MTX midwoofer's extended low frequency range, you will have a great bass response even without a subwoofer. For increased quality be sure to couple the speakers with an amplifier and notice the low frequency even more!

The tweeters are versatile and can be flush or surface mounted anywhere. With the swivel you can adjust the tweeters for imaging control. The crisp highs will give your music the clarity it deserves.

  • You avoid incompatible radios, speakers, or wiring
  • Installation is smoother, faster, and frustration-free
  • You get the correct accessories the first time

Whether you're replacing a factory stereo or upgrading your entire audio system, the Fit Finder eliminates uncertainty.
