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 performing amplifier.
In fact, we back up every Thunder
amplifier with a three-year warranty if
installed by an authorized MTX Audio
retailer (see the warranty statement).
Your new MTX Thunder amplifier was
designed, built and thoroughly tested at our
state-of-the-art electronics manufacturing
facility in Phoenix, Arizona. 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 substantially shorter internal and
external lead lengths. This reduces stray
capacitance and inductance, which results in
cleaner and more accurate musical reproduc-
tion with significantly less noise interference.
The ISMT mounter produces amplifier boards
with smaller and lighter components, which
are more resistant to vibrations inherent in the
automotive 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
performance from your MTX Thunder
amplifier, so we recommend that you have it
professionally installed by your authorized
MTX dealer.

HOW TO USE THIS MANUAL

If you are installing this amplifier yourself, we
recommend that you read the manual cover-
to-cover before you install it. Familiarize
yourself with the features 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.
