UGB AK

The BAK (BMW connection cable) allows easy tapping of the audio signal directly to the BMW under-seat basses. The connection cable kit can be used in BMW models of the E-series / F-series and G-series in which NO original amplifier is installed. This is the case in the equipment lines "Stereo" or "HiFi". The cable kit has high quality BMW connector plugs. These are simply plugged between the signal line of the under-seat subwoofer. The audio signal is led as a high-level tap to the rear to the amplifier, there it is amplified and led back to the subwoofer, here it is amplified fed into the original vehicle tree. The installed speakers are thus operated by means of the installed amplifier. Only a separate power line must be pulled! Content 2 pcs. for the left and right side of the vehicle. Please note the connection diagrams (Service / Downloads).
