	CONGRATULATIONS...
ENGLISH	on your purchase of a new MTX Audio
	the latest Intelligent Surface Mount
	Road Thunder Amplifier! MTX has long
	been the industry leader in mobile audio,
	and we have reached new heights with
	the development of the new MTX Road
	Thunder amplifiers. You couldn’t have
	chosen a more reliable, powerful, or
	better performing amplifier.
	We manufacture every amplifier using
	Technology. Some of the advantages of
	the new design are significant improve-

ments to the amplifier’s electrical and mechanical properties. ISMT devices feature substantially shorter internal and external lead lengths. This reduces stray capacitance and inductance, which results in cleaner and
