Speaker relocation kit by Trial Japan for ND (2016+) Mazda Miata/MX-5. A simple solution for those adding aftermarket seats to the Miata without sacrificing audio quality. Because speakers are built in to the OEM seats, once the seats are removed the surround sound feel drastically changes and can dull the experience. This kit solves that by relocating the speakers to the back bar. Please note that if your car use OEM (Mazda) Sound System (non-Bose), there will only be a relocation kit for the Driver side only as passenger is not equipped with a speaker. Learn More
