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
