TERMINATOR 8" MICRO AMPLIFIED SUBWOOFER ENCLOSURE
Small Stature, Bad Attitude
The TN8MS is the latest release in the Terminator line from MTX Audio. This 8", low-profile subwoofer is designed for use in vehicles where space is at a premium or better yet, where you want it to be invisible like under the front seat. The TN8MS does not disappoint in delivering unexpected bass out in a form that is no bigger than a donut box.
Integrated Amplification
The TN8MS has a high efficiency internal 135-watt RMS, class A/B amplifier designed to deliver crisp sound at all levels. The unit is loaded with features including adjustable gain, bass boost and low pass crossover allowing you to customize the sound to your music and listening style. You can connect the unit to a factory or aftermarket head unit using either RCA cables or high level speaker connections. When you use high level connections, there is no reason to run the remote wire from the head unit as the amplifier will automatically turn on when it senses signal from the head unit making installation quick and easy.
