With broad, horizontal lines, the JBL Club Amplifiers convey a sense of power and performance. The gloss-black trim surrounds a matt-black casing made of die-cast aluminium. The controls and inputs are concealed by the cover, so the amplifiers integrate seamlessly into the vehicle. Even at high output levels, they offer full sound without distortion. The integrated circuitry protects the devices from short circuits, overheating and surges.
