TECH TIP #11:  Using Multiple Outputs on Amplifier

Use only ONE of the the speaker outputs on amplifier. Never connect multiple speaker lines to the same amplifier (4, 8, 16-ohm, 25, and 70.7-volt).  The effect is combining low and high impedance loads in a parallel circuit which causes an unstable condition, thereby resulting in amplifier overload, and damaging the amplifier. Installer, and end-user, be advised warranty will be void if amplifier is found to have failed due to misuse.
