POWER AMPLIFIER OWNER’S MANUAL

CONGRATULATIONS...

on your purchase of a new MTX Audio
Thunder Amplifier! MTX has long been the
industry leader in mobile enclosures and
speakers, and we have reached new heights
with the development of the new MTX
Thunder amplifiers. You couldn’t have chosen
a more reliable, powerful, or better perform-
ing amplifier. In fact, we back up every
Thunder amplifier with a three-year warranty
if installed by an authorized MTX Audio retail-
er (see the warranty statement).

Your new MTX Thunder amplifier was
designed, built and thoroughly tested at our
state-of-the-art electronics manufacturing

facility. We manufacture every amplifier using the
latest Intelligent Surface Mount Technology. Some
of the advantages of the new design are its signifi-
cant improvements to the amplifier’s electrical and
mechanical properties. ISMT devices feature sub-
stantially shorter internal and external lead lengths.
This reduces stray capacitance and inductance,
which results in cleaner and more accurate musical
reproduction with significantly less noise interfer-
ence. The ISMT mounter produces amplifier boards
with smaller and lighter components, which are
more resistant to vibrations inherent in the automo-
tive environment.

A word about power ratings. It is important for you
to know how they stack up. MTX has chosen the
most honest, most conservative way to rate our
amps. We show you the RMS power, at 12.5 volts,
and dynamic power at 14.4 volts. However, we go
above and beyond the call of duty. We test each
amplifier. The technician records the “actual”
power output, and records this number on your
Certified Performance Certificate. The amplifier
must meet or exceed the rated specification before
we’ll ship it. No questions. No exceptions.

We want to ensure you get continuous high per-
formance from your MTX Thunder amplifier, so we
recommend that you have it professionally installed
by your authorized MTX dealer.
