Contains a pair of 6.5" midbass speakers to replace the OEM speakers in Audi vehicles with 8" OEM speakers. The OEM 8" speakers often brake due to their poor design, so if you are looking for a replacement or an upgrade to the OEM speakers then look no futher. The ZDSKAS1 includes the ZX65C midbass speakers with a 60W power handling, 89dB sensitivity and a robust build. ZDSKAS1 is Plug and Play and improves midbass performance and durability.
