2016-2017 Mazda MX5 Miata Bose sub-woofer. Will only work for 2016-2017 Miata's that came from factory with the Bose system and are left hand drive. This is the speaker that goes into the assembly beneath the passenger footwell. This is a great stock replacement if yours was blown or damaged. In good working condition, fully tested prior to removal from the vehicle. Only includes whats shown, you will need to reuse your existing hardware for installation.
