About the MTX Thunder68

Real world speakers

MTX doesn't make speakers that only deliver the goods in a sound lab. These affordable Thunder68 5”x7” 2-way speakers feature a durable polypropylene cone with a rubber surround that'll shrug off the weather and wear that come with living in your car full-time. Depending how low you need to mount the coaxials, you can swivel the soft dome tweeters up to 15 degrees in your direction to really dial in the stereo imaging.

MTX doesn't make speakers that only deliver the goods in a sound lab. These affordable Thunder68 5”x7” 2-way speakers feature a durable polypropylene cone with a rubber surround that'll shrug off the weather and wear that come with living in your car full-time. Depending how low you need to mount the coaxials, you can swivel the soft dome tweeters up to 15 degrees in your direction to really dial in the stereo imaging.

While no car speaker can produce bass like a large subwoofer, these speakers truly shine in the lower frequencies. With up to 60 watts RMS of power handling, you can add to their impressive depth and richness when you power them with an outboard amplifier. 

Grilles are not included; the factory grilles should be suitable for most applications.

Product Research

Features

Woofer Cones: The MTX Thunder Series speakers feature durable and rigid polypropylene woofer cones. Polypropylene is also resistant to the moisture and temperature extremes found in automotive applications.

Tweeters: Each speaker features a 1" treated silk dome tweeter. Silk is lightweight and great for high frequency extension and efficiency. The tweeters pivot slightly within their housings (approximately 15° in any direction), so they can be angled toward the listeners to improve imaging.

Mounting Applications: MTX describes this speaker as a 6x8/5x7; it fits examples of both applications, but the hole spacing is not a perfect match for Ford 6x8 applications. Drilling new screw holes or inserting the screws at a sharp angle may be necessary. Please check the Crutchfield Vehicle Selector to confirm fit.

Q
How is it possible that the infinity primus pr8602cf and the mtx thunder 68 both have the same identical woofer depth of 2-7/16 and the infinity fits a 99 ford crown victoria front doors and rear deck but the mtx thunder do not?

Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget.
