only £624.99 FREE Delivery



To satisfy higher demand on sound and for a significant sound improvement, it is not enough to just replace the factory-installed loudspeakers in the original mounting places. The choice of quantity and quality of speakers, acoustically the right location and individual tuning is important for an excellent sound result.

Due to a limited space installation requires a solution beyond the conventional methods in in-car entertainment acoustics.

The JEHNERT doorboard guarantees utmost perfection in craftsmanship from development to production. With their minimal footprint and low profile they realize an optically smooth integration of a powerful speaker system and use the acoustically best location in the vehicle.

Although these doorboards are best suited with the purpose made Jehnert sound system they are available with or without the Jehnert sound system.

There is either an DOUBLE or QUADRUPLE bass system available. This item is for the QUADRUPLE system, for the DOUBLE system please click HERE.
