Real world speakers

MTX doesn't make speakers that only deliver the goods in a sound lab. These affordable 2-way speakers feature a 5-1/4” 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 across your dash.

While no car speaker can produce bass like a large subwoofer, these speakers truly shine in the lower frequencies. With up to 45 watts RMS of power handling, you can add to their impressive depth and richness when you power them with an outboard amplifier. MTX includes black metal mesh grilles in plastic frames for custom installations, and the unique prorated 5-year warranty really makes these Thunder52 speakers a smart buy.

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


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.

Warranty: MTX offers a 5-Year Prorated Warranty with the following terms:

  • Years 1-2: Products found to be defective in materials or workmanship during the first two years will be, at Mitek's option, repaired or replaced by Mitek at no charge. The warranty period does not renew, but continues on from the original date of purchase.
  • Years 3-5: The purchase price of an item which becomes defective after the first two years and prior to the end of the warranty period will be prorated and credited toward the purchase of a new MTX product. The amount of proration is determined by dividing the original purchase price by the number of months in the warranty period (60), then multiplying the result by the number of months remaining in the warranty period.
