JBL BassPro Nano is an extremely small, active subwoofer that has been specially developed to fit into a vehicle’s nooks and crannies that would be too tight for other active subwoofers. The robust casing, made from die-cast aluminium, is finished in durable, textured matt black, so it blends with any interior. The integrated 100 watt amplifier delivers powerful bass and is extremely efficient, drawing minimal power from the vehicle battery.
