Specifications
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.
