Authorized MTX 

Dealer

MTX Thunder Elite amplifiers are the most technologically advanced amplifiers that MTX offers. Not only are the features and quality superior, but the looks and design of the amplifier puts the Thunder Elite series at the top of the amplifier line.

The Look

The ultimate expression of power and style. The piano black finish and brilliant chrome intake take Thunder to a new level of style. But underneath is still loud and proud MTX power and clarity. Oversized caps, ISMT produced circuit boards, Pure N-channel design, Adaptive Class D technology, and so much more combine to create the best sounding car audio amplifiers...ever.

The new and improved Prizm EFX with the addition of white light, the option of stealth mode with no lighting and the dazzling display of demo mode.

The Technology

Thunder Elite amplifiers offer the most extensive array of sound enhancement features of any Thunder amplifier. With the multitude of equalization settings, crossover options, subsonic filters, and other comprehensive adjustments all located on the top of the amplifiers, dialing in the perfect sound is easier than ever.

Thunder Elite amps feature MTX Smart Engage technology making it easy to add Thunder amplifiers to any factory or aftermarket system—without additional adapters or converters. You get to keep your factory A/V system, steering wheel controls and navigation without removing the factory source. Designed by xtant technologies, the fan brings the amplifier to a whole new level. Not just a fan, XTC is a self adjusting, turbo-charged intercooler that intelligently supplies cool air evenly and constantly over all devices based on the amplifier's demand.

Good Amp

I bought this amp to run my front and rear 6.5 speaker components.

It has a bulit in fan that keeps it from running hot

The display colors are by far the best l have ever seen on an amp, even better than Audiobahn

The sound is clear, and overall is one of the best 4 Channel amps l have ever purchesed, and I have owned many in my life time

I plan on buying another one when l pick up a Lexus GS 300 this winter.

Freakin' Sweet

not only is this amp very sleek to look at but damn this amp powers my two sets of kicker ss56.2 loud and clear, I thought i needed more power but this is enough. I can hear the songs clearly about a block away, and damn this a great price. I couldnt find anywhere lower than this not even ebay and forget retail stores. If you want the latest powerful amps that nobody in your area has get mtx elites!

Great Price & Product.

I would recommend this product. Sounds great and very stylish. Just be very careful when installing this amp or any of the TE amps. They scratch very easy.
