When you're driving a Mazda MX-5 Miata on a curvy, country road on a beautiful day, with the top down and the wind on your hair, music probably isn't all that important. You might be quite content to write your own mechanical symphony using the high-revving engine, the occasional chirp from the tires, and your own perfectly-timed downshifts. We totally understand. In fact, we'd like a ride sometime.
The second-generation Miata debuted in 1999 and received this mid-cycle update in 2001. The cosmetic changes were well-received, but country-road driving enthusiasts were much more excited about the bump in horsepower and the wider availability of the optional six-speed manual transmission. With or without the 6-speed, the sound of an enthusiastically driven Miata is a wonderful thing.
But, let's face it, into each life a little rain must fall and the only thing to do when that happens is put the top up and enjoy some music. You're still driving a great little car, so why not enjoy some great stereo sound?
Factory stereo system
The 2001-2005 Miata was available with several different stereo packages. The base package was a single-disc AM/FM/CD receiver and four speakers in the doors. Upgrade options were an in-dash 6-disc changer and a Bose® system with larger speakers and an external amplifier. From 2004-up, Mazda added two more speakers to the Bose system, behind the seats in the windblocker.

Replacing the factory stereo
No matter which stock system you have, removing the Miata's factory stereo is an uncomplicated process made easier by the detailed, step-by-step instructions found in the Crutchfield MasterSheet™ that's free with your stereo purchase.
You'll use a panel tool to pry off the plastic DIN-hole covers on either side of the factory radio. Once that's out of the way, insert either two DIN tools (for the Bose system) or four DIN tools (for the base system) into the holes on either side of the radio. (These DIN tools are free with most Crutchfield receiver orders.) Push the tools into the holes approximately 1", until you hear a click from each tool.

It's important to be patient and even gentle with your car during this process. Excessive force can damage the retaining clips, and you'll need those later. Once everything has "clicked," spread the tools apart just a bit and gently pull the radio out of the cavity. Disconnect the wiring harness, unplug the antenna cable, and you’re done.
Like the rest of the car, the Miata's radio cavity is rather snug. Still, a nice selection of single-DIN (2") or double-DIN (4") receivers will fit in the dash. Receiver depth can be an issue, but Crutchfield's extensive database will ensure that you purchase a receiver that fits into your dash. You'll need a mounting kit to trim out your new stereo, a wiring harness to connect the new receiver without cutting the Miata's factory wiring, and an adapter that connects the antenna. Crutchfield includes these installation parts free with most orders.
If you plan to keep the factory radio and upgrade your system with a Bluetooth®, satellite radio, or iPod® adapter, you’ll still have to remove the factory radio to connect any of those adapters.
Factory amplifier: Miata's that have the Bose system come with a factory amplifier. When you install a new receiver in an amp-equipped Miata, you'll also need a special integration adapter. The adapter, which is available at half-price with your Crutchfield receiver purchase, allows you to install an aftermarket stereo in vehicles with Bose premium factory systems. The Bose amplifier is located behind and below the car's heater controls. The amp wiring harness can be reached from below the dash on the driver's side.You unplug it from the amp and plug the integration adapter into it.
Tools needed: Small flat blade screwdriver, panel tool, DIN tools
Steering wheel controls: If your car is equipped with steering wheel controls, you'll need a control interface if you want to keep using them after you install a new receiver. There are several available, but the PAC SWI-RC interface is the one that will work with the Miata.
Replacing the factory speakers
When you're planning to add a new stereo to your Miata, it's important to think about how, and how much, you're going to use it. A new receiver is always a good first step, simply because the additional features (Bluetooth calling, iPod connectivity, etc) can make a big improvement in the fun and functionality of your car. If you're obsessed with great sound (Since you're reading the Crutchfield website, that’s a distinct possibility!), you'll definitely want to upgrade your speakers. But if you're happy enjoying the sound of the engine and the feel of the wind in your hair, there's no need to rush.

The speakers are easy to get to, at least. You'll need to remove the door panels, but that's a straightforward process that shouldn't take very long at all. The ease of installing new ones is largely dependent on which version of the Miata stereo you have and how skilled you are at basic fabrication work.
The factory Bose speakers are a rather interesting 8" in diameter. As you might expect, exact replacements are about as easy to find as a Miata competing successfully on the demolition derby circuit. You can replace the Bose speakers with a wide variety of 5-1/4" or 6-1/2" speakers, but you'll need to fabricate your own mounting brackets. If you're not comfortable doing your own fabrication work, you might want to leave the job to a car stereo installation professional. Or you could just leave them where they are. They're Bose, and for this particular application, they're quite good. A new receiver will make them sound even better.

The base stereo, on the other hand, comes with a pair of perfectly normal 6"x8" speakers in the doors, so it's a lot easier to find and install their replacements. Some 6x8's fit right in, but with others, you'll need to cut out the back of the plastic factory cup (or mounting bracket) to create some extra depth for your new speakers. The word "cut" can be scary, but all you're really doing is snipping away at plastic. Work carefully, take your time and all will be well. Of course, if you simply don't want to cut anything in your car, you can always install a pair of 5-1/4" or 6-1/2" speakers.
Tools needed: panel tool, Phillips screwdriver, small flatblade screwdriver
The Miata's tweeters are mounted in the upper front of each door, near the mirrors. In terms of sound staging, these 2", 4-ohm tweeters are in about the best space they can be in a car like this – up near your ears. Once you have the door panel off, they're not hard to remove, but replacing them will involve fabricating a new mounting bracket. On the upside, you won't have to splice wires because there are wiring adapters available for this location.
In 2004, Mazda added the Windblocker panel, located behind the Miata's seats. This handy panel, designed to reduce top-down bead buffeting, contains two full-range speakers. We have not yet had an opportunity to research speakers for this location, so we're not comfortable making recommendations at this time. The good news is that the Miata community is full of active, enthusiastic DIY enthusiasts, so you may want to consult your area Miata club, or visit one of the many Miata forums online.
Bass in your Miata
If you want to hear serious thump coming from somewhere other than the expansion strips you're driving over, you'll want to add some bass to your Miata. How much bass is up to you of course, but if you've spent any time with these cars, you know that even a second-gen Miata's trunk is only large enough for weekend's worth of duffle bags. Sure, you could install a custom-built sub box in the trunk (37" W x 10" H x 21" D on non-Bose models, slightly less with Bose), but that depends on how your passenger feels about a lapful of luggage. We've seen it done and it's pretty cool, but unless your Miata is primarily used as a show car, we'd suggest a small powered subwoofer instead. You'll get the bass you want and retain at least a smidgen of luggage space.

Speaker baffles: A set of these waterproof foam baffles can help you get the most out of a new set of speakers. The soft baffles compress easily within the Miata's doors, forming a seal that reduces panel vibration and improves sound. If you cut a hole in the bottom of the baffle, or remove the entire bottom, you'll maintain good bass response while still protecting your speaker.
iPod® and satellite radio adapters: If you don't want to replace your Miata's factory receiver, you can still add versatility to the system. We offer several adapters that will allow you to use an iPod, MP3 player, or satellite radio with your Miata's factory system. With a car like this, anything that allows you to leave that bulky CD album at home is a good thing.
Security: If you're thinking about adding security or remote start to your Miata, we offer several options. The FLCAN FlashLogic module connects to your vehicle's databus interface, enabling communication with a wide variety of security systems. It’s the place to start when shopping for a security system.
