Restore Your Factory Audio System With Optical Fibre Compatibility
This decoder box solves a common problem for owners upgrading or replacing car stereos: preserving Bose and Harman Kardon sound systems that rely on optical fibre connections. Rather than losing your premium factory audio when fitting aftermarket equipment, this adapter bridges the gap between your vehicle's original optical interface and newer radio installations.
The unit works by accepting the factory fibre optic signal from your car's wiring loom and converting it so your new stereo can communicate with the existing amplifier or sound processor. Installation is straightforward—simply disconnect the black connector from the decoder box, attach your car's factory fibre plug, reconnect it, then wire the ground and audio cables to your new radio. The gold-plated connectors ensure reliable signal transmission without degradation over time.
Measuring just 7.4 x 5.5 x 2.5 cm, it fits neatly behind the dashboard or in the boot area. Built from copper wire and a plastic housing, it's designed to handle 12V automotive electrical systems reliably. Before purchasing, confirm your vehicle matches the compatible models listed or contact us with a photo of your current radio setup—this ensures a perfect fit and avoids installation issues down the line.
