BOSE amplifier integration interface for Alfa Romeo 147, 156, 159, Brera and GT vehicles. Check the original BOSE system and connector arrangement before ordering.
The interface converts the replacement stereo’s speaker-level output to the level needed by the original BOSE amplifier.
A pre-wired mini-ISO connection is supplied for amplifier turn-on on vehicles without steering-wheel controls. With a steering-control interface, follow the supplier instructions for the turn-on connection and do not use the separate red connector where the interface already provides it.
Connect the amplifier turn-on supply as specified in the fitting instructions, using the replacement stereo’s appropriate accessory or amplifier-control output. Confirm the exact factory audio equipment before installation.
