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
