About the Audison APBMW BIAMP 1
From our tech experts at CEN
A plug-and-play harness for BMW and Mini, for bi-amplifying the factory speaker locations.
Who it suits
BMW and Mini owners upgrading a factory system who want the work reversible and the vehicle returnable to standard. This matters most on cars with amplified or fibre-optic factory audio, where cutting into the loom is not an option.
Our tech experts advise
Harnesses are specific to vehicle, year and which factory system the car was built with, and the wrong one simply will not work. We confirm against your exact vehicle before ordering — get in touch. See car audio installation.
