TN8MS Subwoofer Kit

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 bassout in a form that is no bigger than a donut box.

TN8MS Subwoofer Kit

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 headunit 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 headunit as the amplifier will automatically turn on when it senses signal from the headunit making installation quick and easy. The unit also includes a remote bass knob that connects to the amplifier via included 3.5mm cable enabling you to adjust the bass level from the comfort of the driver's seat.

TN8MS Subwoofer Kit

Low Profile

The TN8MS is designed in the smallest form factor possible to still be able to produce MTX approved bass. The unit is all inclusive, with the amplifier and subwoofer mounted in an optimized enclosure. The enclosure has a total height of less than 3.1" making it perfect for installation under a seat or behind a truck seat. Don't let the small size fool you, the TN8MS delivers incredible bass that will surprise and impress even the craziest bass heads for its size.
