The Nakamichi NBF618S is the smallest Nakamichi underseat active subwoofer, but smallest doesn’t mean it’s the quietest.

Featuring 100 watts of RMS power driving a 6×8 inch woofer, the NBF618S is slim and designed to be easily installed beneath the seat and provide an instant boost to the low frequencies from your original factory source unit or aftermarket units.

At just 72mm in height, the NBF618S can easily fit beneath most seats, including the newer electrical seats that come with most vehicles nowadays, ensuring easy compatibility.

Compatible with both high and low level inputs for both factory supplied units or aftermarket units. Add on a Nakamichi DSP for even more tuning possibilities.
