The Aerpro APS67 Speaker Plug Adaptors suit Tesla Model S, 3, X, Y and select Audi vehicles, converting the original speaker plugs on the 4" midrange (Tesla) and Tweeters (Audi) into standard size aftermarket speaker terminals. The plug and play design enables speakers to be installed into the vehicle without the need to cut the original vehicle wiring loom, resulting in a simple yet professional installation that can be reversed at any time.
