The TN400/4 is a 4-channel class A/B full range amplifier designed to power Terminator full range speakers. The TN400/4 features a unique variable fan cooled design that allows it to manage heat build up based on output. As the amp is played louder the fan spins faster and when the volume is lower the fan spins slower. The TN400/4 additionally includes MTX's Smart Engage auto turn on technology that eliminates the need to run a remote wire to activate the amplifer during installation saving time and possible damage to the dashboard.
