POWER AMPLIFIER OWNER'S MANUAL
Introduction
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 perform-
ance from your MTX Thunder amplifier, so we rec-
ommend that you have it professionally installed by
your authorized MTX dealer.

HOW TO USE THIS MANUAL

If you are installing this amplifier yourself, we rec-
ommend that you read the manual cover-to-cover
before you install it. Familiarize yourself with the fea-
tures and details on the input and output panels.
Make sure you have all the equipment you need.
Then follow the step-by-step installation instructions
included. Sample installation diagrams may be found
