Fitment guarantee and VIN verification

Every B&O transducer undergoes a voice coil resistance test with a digital multimeter and an audio test for frequency clarity and absence of mechanical resonances.

Fitment / installation tip: The initial designation 4K0 (electronics and audio group 035 / 298) defines a speaker optimized for the geometry of the right door cavity in the MLBevo platform. The most common reason for replacing this transducer is crackling at higher volume levels caused by a fatigued voice coil or diaphragm damage from moisture entering through a leaky window channel. Using an original OEM speaker restores full dynamics and soundstage clarity without the need for installation modifications or computer coding. Before purchasing, we recommend checking the equipment code on the sticker in the trunk (PR: 9VS or 8RF) or verifying the part number according to the vehicle's VIN.
