Terminator amplifiers have a reputation for power and their objective is to deliver high quality sound and performance at prices anyone would be foolish not to take advantage of. POWER OF TECHNOLOGY: Terminator amplifiers have been totally redesigned to incorporate high quality aesthetics with the latest technologies that allow Terminator amplifiers to run as long as you do. All three models have a high sheen, gloss black cover that adds a powerful feel to any installation. All three models share the same size and footprint and all the connections are on one side making it easy to create a custom looking, clean installation. Rather than weighing you down with heavy aluminum heat sinks, Terminator amplifiers are cooled using a variable speed internal fan that is normally reserved for our highest end amplifier lines. As you turn your volume knob clockwise until you can't take it anymore, the amplifier output is increasing which engages the fan to automatically increase its speed allowing more cool air to enter the amp. This keeps the amplifier performing at its peak level longer and prevents the amplifier from having to go into thermal shutdown due to overheating. As you turn your system down to hear what your friends are saying about your system after you see them bobbing their heads to the beat and grinning from ear to ear from the back seat, the fan automatically slows down as the volume decreases.
