This listing is for a pair of the world's best-selling replacement door speakers for the Mazda Miata! The 3rd Millennium Audio M800 is a 2-way design with an OEM fit. No cutting, wire splicing, or modifying your Miata is required. Just screw them and start enjoying the best music your Miata has ever experienced. This listing is for a set of (2) M800 speakers (left and right doors).

Includes detailed, full-color installation instructions plus a link to our YouTube channel where you can watch actual complete installations for your 1990 - 2024 Miata (on YouTube, search for '3rd Millennium' to find our channel. eBay won't let us post the link here).

For this listing simply select the model year for your Miata and you'll get everything required for the installation. 1999 - 2015 models require our AD1 Mounting Kit which is included when you select your model year. 2016-2024 models require our AD2 Mounting Kit which is included when you select those model years.

IMPORTANT: These speakers (or any normal speaker) will not work correctly in the 2009-2015 Miata with the factory Bose radio setup. The Bose amplifier limits the frequencies the speakers receive so a normal door speaker when installed will only get low frequency signals. 

Other years with a factory Bose radio will work fine although maximum output will be reduced somewhat although most users have reported there is still plenty of volume available for normal listening.

We have more details about Bose compatibility on our regular website at 3maudio.com. eBay won't let us post a link, so please browse there directly.

Your new M800s include a full 1-year warranty and a 30-day no-questions-asked money back (less shipping) return policy if you're not satisfied for any reason, so purchase with confidence. 

We are the manufacturer and no other website (except our own main site and this eBay store) sells the M800s, so if you see them elsewhere, please contact us as it's likely a scam.

Any questions? Use the 'Contact Seller' link and we'll be glad to help you out.

Reviews

Wow! Was the installation of headrest and door speakers a snap! There is something to be said for utilizing speakers that are a direct and perfect fit. The sound quality improvement is fantastic. Even with an unmodified factory radio the sound is full and massively improved. Scott, Minnesota

I just got through installing the door cards and used bluetooth to connect to my phone. Then I sat in the car and turned on a familiar playlist. OMG! It is awesome. I am no audiophile. I just wanted a decent sounding system. It's almost like using headphones. Rich bass clear and crisp and plenty of volume. I have another Miata and I think I have to put a set of your speakers in that one too. I could not be happier. Rich, Michigan

Just installed your speakers in my 2001 Miata and could not be happier. From the ordering to the installation your guidance was spot on and the speakers sound awesome!, Patrick, Connecticut

Just received the M800 door speakers and Millennium-5 headrest speakers. Within 20 minutes after opening the box, I was done with the installation, and all I can say is WOW! Not only are they the easiest replacement speakers ever, they sound incredible even with the stock head unit. Thank you!!, Todd, Pennsylvania

Just installed the M800 and they really do the job. Between those and the M200s it's like a whole new system and didn't have to push the volume for normal listening. At rest 5 or 6 was good, now 8 or 9. I cranked it way up just to see and the speakers handled it well. I'm an old timer and over the decades one of the first things I would do is upgrade speakers, usually doing the work myself. This has been one of the easiest and best upgrades for the money I have ever done. Great job!!"  Jim, Oregon

I installed my speakers today and they are absolutely fantastic! I've read great reviews about them but they completely exceeded my expectations. It's hard to believe the sound difference with just a speaker change while still using the factory head unit., Alan. Vancouver Canada

I’ve just finished the installation and...ESPECTACULAR!!! Congratulations for this high quality product strongly recommended., Gabriel, Madrid Spain

I was quite a bit skeptical. I just finished installing them. I'm blown away. I thought that there might be a just little difference, but I was wrong. These are phenomenal speakers. They "hit" hard. I don't think these will require an amp, but it's nice to know that these will handle an amp. They really make my factory head unit sound materially different. Honestly, I was extremely skeptical., Brad, North Carolina

Just installed the M800 and Baffles in my 1990 Miata and they are awesome! I have never sent a review to any manufacture as I always expect good results from any product but these are amazing. Thank for a great product and excellent service, Armando, Georgia

Holy {bleep}!! These speakers are amazing!! They really sound good!! I’m a believer now!! Larry, Maryland

Just wanted to let you folks know that the M800 speakers I purchased were almost too easy to install and they sound fantastic.  Keep up the great work! Bob, Rhode Island

I just installed a set of the M800 speakers from 3rd Millienium and in comparison to the Polk DB651s that I installed last summer in my NA, M800's sound output over the OEM and in my application, the Polk's, is astonishing. My complaint with the Polk's was a lack of bass response. The M800's restored everything I remember with the OEM speakers, plus a huge increase in clarity AND bass response. At this price and being a direct fit, no drilling required, they are hard to beat. Chris, Worcester MA

Just installed the M800's in place of the Pioneers' today and I am very happy with them! I am by no means an audiophile and had given up on my Miata in regards to a decent sounding system. Your speakers have "more" of everything !!! Jose, Glendale CA

Very pleased with the M800s. My husband installed them in under 30 minutes. Cory, Texas
