Whether you want to repair your Miata radio or install an aftermarket one, our Mazda Miata Stereo Wiring Diagram is a handy way to get things done. Most Miata stereo installs take just a day and can be easily done, especially if you have the right install kit. Many times these install kits will include a flying loom for your stereo, so it makes wiring a plug and play affair.
However if your new Miata stereo doesn’t come with an industry standard hookup, or lacks a wiring loom connector, you’ll need our diagram. Our Mazda Miata Stereo Wiring diagram helps you connect the speakers to your deck output, and your amplifier if you are installing one.
Removing your Mazda Miata factory radio is easy to do with a handy How-To tutorial. Once you have the factory unit removed, it’s just a matter of installing your plastic bezels and wiring up your new Miata stereo.
The Miata has undergone just a few changes during it’s long life, which is a solid testament to the incredible build quality and balance of Mazda’s roadster. If you are looking for the newest changes to the Miata, or want to check out the MX-5 Speedster that Mazda debuted at the 2015 SEMA Show make sure to subscribe to My Pro Street for more news.
