Compact and powerful active subwoofer in a sealed enclosure, it can be fitted in the load compartment or even under the seat due to its space saving, ultra-flat design (not in combination with electrical seat adjustment when fitted under the seat). The subwoofer is capable of taking both low RCA line input or high speaker line input, meaning you can connect it to your aftermarket or original factory fitted stereo to upgrade the sound you already have. Additional universal loudspeaker cable might be required in some cases (approx. 0.5 m)
