SKU# M800 from $79.99 $71.99 set of 2
Direct-fit premium sound is now available for your 1990 - 2015 Miata! Over a year in the making, let us introduce you to our M800 2-way door speakers! Available exclusively from 3rd Millennium, the M800's are an exact fit for the 1990-1997 doors (1999-2015 Miata's require our AD1 Mounting Kit - select bundle below. Not compatible with Bose radio/amps). The M800's just screw into place with no drilling, cutting, or modification of your Miata. We've even manufactured the M800 with a special harness so they just plug in to your existing door wiring. It's a screwdriver-only plug and play install!
And the sound is an astonishing improvement over stock
or cheap aftermarket speakers.
We designed the M800 (and the value priced M600) specifically for the Miata doors. The
M800 features a polypropylene woofer cone, a large magnet structure, a butyl
rubber surround, and a 1" mylar tweeter with crossover. The result?
Extended low frequency response with an ultra-smooth high-end.
Coupled with our Millennium-5 headrest speakers,
you'll have the ultimate sound experience in your Miata.
Installation in your Miata literally takes minutes and only requires a screwdriver as the M800s are an exact fit and use the existing speaker screw holes (requires our AD1 Mounting Kit for the 1999-2015 Miata - package below). And with our included harness adapter, you simply plug them in to the stock factory wiring. There's no splicing, soldering, crimping, drilling, or struggling to install.
The M800s are true premium-quality music speakers and have many improvements over factory and generic replacement speakers including:
Note that if you have a 1999-2015 Miata, you will need to select our bundle that includes our AD1 Mounting Kit (at a special reduced price compared to purchasing separately) which gives you a plug and play install.
Optional Rainshields: Especially in the 1st and 2nd Generation Miata's, if your door window belt molding is worn and leaky, a lot of water gets into the doors. 2006-2015 Miata's have much less of a problem with water in the doors because of the way the inner door assembly is constructed. The XTC65 baffles are an economical and simple way to protect your speakers. Just cut out the lower half and install. Watch our video to learn more.

Bose info: Because these are standard 4-ohm speakers, they are not directly compatible with Bose radios/amplifiers. 1999-2008 Miata's with a Bose radio/amp can use the M800s but will experience reduced maximum output due to the M800s being a 4-ohm impedence compared to the Bose 1-ohm. But most users report the volume levels achieved still more than adequate. And with the Bose system, you will also want to disconnect the stock Bose tweeter. It's 4-ohm but overly hot and since the M800s are already a 2-way design with a superior tweeter, the stock tweeter is best left disconnected.
Our M800/M600's will physically fit perfectly in the 2009-2015 Miata doors with stock Bose speakers, but operation will not be correct with the stock Bose amp as Mazda/Bose built the crossover into the amp itself so that the door woofer and tweeter are fed frequency-limited signals.
But with either an NB or NC, if the Bose radio/amp have been replaced with a normal head unit and/or amp of any make, our M600/M800's will fit perfectly in the doors regardless of the factory speaker setup.
When you order you will receive (2) brand new M800 speakers. We offer a 30-day 'no questions asked' money back guarantee and a full 1-year warranty.

"Just wanted to let you folks know that the m800 speakers I purchased were almost to 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 3rdMillienium 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
