Introducing the M170s! The M170s are a perfect drop-in upgrade for the round speakers found in the 90-97 Special/Limited/and M-Edition Miata's. It's a 10 minute plug-and-play installation and the sound is a massive improvement over the OEM speakers. Learn more here
Door Harness Adapters for the 2016-2023 Miata! We now have the adapters to install our M800s speakers into the 2016-2023 Miata doors. No cutting or splicing wires - just plug them in. $5.19 for a pair. Standard 205/110 connectors. Purchase here.
Door Panel Grommets for 1990-2005 Miata's! I know it's a little thing, but it's much better to mount your door speakers with the correct mounting grommet to avoid vibration. And metal Tinnerman-style clips are not recommended as they will scratch up your door panel and can rust.
These grommets replace the factory pieces in the doors of your 1990 - 2005 Miata. You need (3) for each 90-97 door and (4) for 1999 - 2005. Just $5 for a 4-pack. Order here

And for NC owners, check out installing our Air Horn Kit and installing our Battery Disconnect. Both in our 2012 Sport. So check out all the good content up on our YouTube channel.
I wanted to pass on how pleased I am with the products that I ordered. Between the 6 speakers, the rain shields and the battery disconnect I think I maybe spent a half hour tops installing. Everything fit exactly as promised and was so simple to switch out! Not to mention how thrilled I am with the sound of the radio now.
