In a Nutshell

The Boxster's stock stereo systems aren't awful, but you can definitely do better. Replacing the factory receiver will give you better sound and up-to-date functionality, so that's a great place to start. In this article, we'll tell you how to do that and replace the speakers, too. 

The compact cockpit contains an impressive number of speakers. The dash speakers are very easy to deal with, and the door speakers aren't much more complicated. You'll need to drill new mounting holes for the door woofers, and you'll also need speaker connectors throughout, but generally speaking, this is a job the average DIY-er can totally handle. You'll also have some options when it comes to adding bass with a powered subwoofer.

Upgrading the stereo is just the beginning. You can also improve your top-up visibility with a rear-view camera and improve your parking lot security with an alarm system.

Overview of the Porsche Boxster

Automotive journalists can be a cranky bunch, but if you send them out with something sleek, fast, and fun, they'll usually come back grinning from ear to ear and ready to write nice things. Don't believe us? Check out contemporary reviews of the second generation Porsche Boxster, most of which read like a teenage love note.

That said; they had a point, and you'll be tempted to ask if there are any more like that at home when you see a Boxster in person. They really are beautiful, they do sound wonderful, and it's way too easy to imagine how much more fun that person's commute is compared to yours.

No need to be overcome by jealousy, though. If you're tired of watching happy Boxster people fly by in the fast lane, take action. You can be one of them for a lot less money than you think, which will leave some dollars left over for an audio upgrade.

This article is an overview of your vehicle's audio system and its upgrade options. If you're looking for step-by-step instructions on how to install a car stereo or speakers in your Boxster, there's nothing better than our exclusive Crutchfield Research Notes™. This detailed, well-illustrated document is free with your Crutchfield order, or you can purchase one separately for $9.99.

Factory stereo system

The Boxster's stereos came in two flavors — nav and non-nav. Those receivers played through two kinds of system – base and Bose®. We haven't researched the Bose version yet, but the receiver and speaker locations are the same in each, save for the Bose system's rear-wall speakers. There's plenty of knowledge out there, though, and if you have some, please share what you know in the comments section below.

Porsches, even the "affordable" ones like the Boxster, are designed by seriously serious engineers, and that can sometimes lead to some seriously complex, over-done stuff. The Boxster is largely free of all that, so working on this purebred sports car isn't nearly as brain-melting as it could be.

You'll lose the factory nav functionality when you replace the stock receiver, but new ones work better anyway, so that's not a big deal. In some models, there's a factory CD changer in the front trunk, which we assume you won't need anymore.

Replacing your factory radio

We've already said that the Boxster's stereo isn't too hard to work with and we're standing by that assertion. It is, however, a bit fiddly in places, so it's important to review the tool list before you start and stay patient while you're working. Complete, illustrated instructions can be found in the Crutchfield Research Notes that are included free when you buy your stereo or speakers at Crutchfield.

American International's POR911 dash kit allows you to install a new single-DIN (2" tall) or double-DIN (4" tall) car stereo in your Porsche. The kit is available with a black or silver finish, so make sure to pick the one that matches your dash. The kit has its own instructions, so pay attention to those when it's time to put the new receiver in the dash.

The wiring harness (also included at a discount with your Crutchfield purchase) does not have an accessory power connection, so you'll need to connect your new car stereo to accessory power in your vehicle. Also, the functions of the yellow and red wires in the wiring harness are reversed. The yellow wire supplies ignition power, and the red wire supplies constant power. If you run into any challenges, you'll be glad to know that buying a stereo at Crutchfield entitles you to free tech support for the life of your gear. Give us a call if you need us. We're here to help.

Tools needed: Torx T-20 & T-30 drivers, 5mm hex wrench

Replacing your factory speakers

The Boxster crams a lot of speakers into a pretty small space. There are three in the dash, two in each door and, on models equipped with the Bose system, speakers in the rear of the cockpit.

Center dash speaker

The center dash speaker is very easy to deal with. Use a panel tool to gently pry up the rear edge of the dash grille and release two retaining clips, then pry up the front edge to release one more clip. Set the grille aside, loosen the two Torx T-20 screws securing the speaker to dash, then disconnect the harness and remove the speaker.

There's no mounting bracket available, so you'll need to use our universal backstrap (or hot glue or silicone) to secure this speaker. There's no wiring harness available either, so you'll need to use a set of Posi-Products speaker connectors to connect this speaker to the factory wiring.

Tools needed: Panel tool, Torx T-20 driver

Corner dash tweeters

The story is similar on the corners of the dash. To remove these speakers, pry up the rear edge of the grille to release two clips and remove the grille. Pry outward on the two metal clips securing the tweeter to the dash, then disconnect the harness and remove the tweeter.

You'll need to figure out mounting solutions here, too, and you'll need some more Posi-Products connectors as well. Oh, and when you're choosing your speakers, keep mounting depth to a minimum. If they're too deep, the factory grilles won't fit.

Tools needed: Panel tool

Door midrange speakers

With the dash tweeters handling the highs, the Boxster's 5-1/4" mid-range speakers take care of the middle of things. They're attached to the door panels, which you'll need to remove. This also exposes the woofers, which are attached to the door frame, so you're kind of saving some work, sort of.

Starting at bottom edge, use your panel tool to pry out the sail panel. Slide it up to remove it, and, on the driver's side only, disconnect the harness. This will expose a Torx T-30 screw, which you'll need to remove.

Open the door release handle and remove the Torx T-20 screw that secures it, then remove the handle. Pry off the screw cover in the door release trim and remove a Torx T-30 screw. Next, pry off the door pull handle's outer cover and remove two exposed T-30 screws. Pry off the screw cover on the rear edge of the door and remove another exposed Torx T-30 screw.

Now you're ready to remove the panel itself. Pry out the sides and bottom of the panel to release nine clips, then disconnect the door release cable and harnesses. Lift up the panel to remove it, and set it aside, preferably on an old blanket that will protect the panel while you're working on it.

Finally, you'll remove four Torx T-20 screws securing the speaker to the door panel, disconnect the harness and remove the speaker. A wiring harness isn't available, so here's another reminder to stock up on Posi-Products connectors.

Tools needed: Panel tool, Torx T-20 & T-30 drivers

Door woofers

If you've made it this far, you're basically ready to replace the 6-1/2" woofers, too. These speakers are powered by an amp in the front trunk and they're secured by four 5mm hex screws. Same-size replacements are available, but you'll need to drill three new screw holes to mount the new speakers with the mounting brackets included with your Crutchfield speaker purchase. You'll need some Posi-Products connectors here, too, of course.

Drilling new mounting holes isn't hard, but you are drilling into a Porsche, so it's okay to take a deep breath before you do it. Recommended, in fact. We also recommend surveying the area you'll be drilling into, working patiently while you drill, and wearing eye protection the entire time. You can do this, just be careful when you do it.

Tools needed: Panel tool, Torx T-20 & T-30 drivers, 5mm hex wrench

Rear wall speakers

As noted above, we have yet to research these speakers, which are found only in Bose-equipped Boxsters. If you have replaced yours, please share your knowledge in the Comments section below. And maybe send a picture, because we could really use one here.

Bass in your Boxster

There's some room for a subwoofer box in the Boxster, but not much. The available space measures 18" H x 28" W x 12"/7" D. If you go this route, make sure the enclosure is situated with the woofers facing up.

Considering what the Boxster is truly made to do, you'll probably be happier with a powered subwoofer. Do you really want to drown out that engine sound with huge, whomping bass?

Other options for your Boxster

Here are some other ideas for your Boxster.

Rear-view cameras

With the top up, the Boxster is not the easiest vehicle to see out of when you're backing up in a crowded parking lot.  We offer a wide variety of rear view cameras that will make that a lot easier, and there's a healthy variety of options to choose from. You can go for a camera that mounts to your license plate and works with your new aftermarket nav receiver, or choose one that mounts onto your rear view mirror.

Add an amplifier for better sound

Replacing the factory radio and speakers will make a big difference in the sound of your music in the Boxster. But when you're winding your way down the road with the top down, you might need a little bit more power. To further improve the sound quality, consider installing a 4-channel amplifier. Talk to one of our advisors to get some ideas for how to build your system.

Security

Installing a security system in your Boxster isn't easy (security systems rarely are), but even though most car thieves can't drive a stick, it's definitely a good idea. Our Crutchfield Advisors can help figure out what you need to get the job done, but we usually recommend taking your car and new gear to a professional installer.
