November 5: New videos! Installing our M600 or M800 speakers into an NC Miata! Watch here or on our YouTube channel.

And soldering! While all our speakers are plug-and-play, sometimes you need to get a bit more involved if you're restoring your Miata or fixing significant damage from a previous owner. So based upon customer request, we've put together a short video showing you how to make a perfect electrical solder connection everytime - guaranteed. Check it out at youtube.com/c/3rdMillennium 

New item! Restoring your NA/NB door wiring? We now have the correct speaker harness plug connector available. Exact OEM match!

And our new Air Horn Kit is now shipping! Same price as the old Stebel kit but now with the much better quality air horn made by Marco of Italy. Sound like a Ferrari!

If you already have one of the compact Nautilus horns you picked up somewhere else, we are making our high-quality mounting kit available for you as a separate item. See our Stebel Installation Kit as a standalone item.

Just replacing the existing headrest speakers? We have another video that covers the simple installation of our Millennium-5 speakers. Watch on our site here or on our YouTube channel.
