Bored with Sudoku? Here's a math challenge for you: Try to figure out how many individual human beings have taken at least one ride in the Ford Crown Victoria.

Think of all the Crown Vics you've seen in the rental lot at the airport, or in the busy, taxi-filled streets of your nearest major city, or (gulp) in the median just as you crested a blind hill. And that's not even counting the Crown Vics that rolled out of the dealership into a cushy life as a regular family car, of which there were many. The numbers have to be absolutely staggering.

Look at it this way: in all likelihood, everyone you've ever known has probably been in a Crown Vic at some point in their lives – hopefully because they wanted to be, but we're not judging…  And if any of those people rode in a Crown Vic cab on the way to see a Kevin Bacon movie… Oh, wow…. This isn't just a big car; it's a big part of our shared culture. They really don't make 'em like this anymore, but with some upgraded audio gear, you can make your car a great place to enjoy music in comfort and style.

The Crown Vic wasn't produced for civilian purchase after 2007, so all later models were made for fleet use. The Mercury Grand Marquis, to which the information below also applies, was sold in dealerships until 2011, when the entire Mercury brand ceased to be. In fact, the very last Mercury that rolled off the assembly line was a Grand Marquis.

Note: For simplicity's sake, we'll refer to the car as a Crown Vic throughout the text, unless we're addressing a Mercury-specific topic. No disrespect to the storied Mercury brand, but "Crown Vic" is a lot easier to type.

Factory system

The classic Crown Vic system was an AM/FM/CD/cassette unit with 4 speakers. Even when new, its performance could best be described as "adequate," so there's plenty of room for improvement. There isn't room for a 4" tall double-DIN receiver, however, which might surprise you.

When you glance at the dash, it's only natural to assume that you can pop a big-screen nav receiver into that opening with no trouble at all. Looks can be deceiving, though. A double-DIN can be made to fit, but not without extensive, detailed modifications to the dash opening. Same goes for receivers with flip-out video screens. This might seem odd at first, but it's not at all uncommon on a number of Ford models equipped with this factory radio.

For that reason, we recommend a single-DIN receiver for your Crown Vic. You won't get the big screen, but there are a number of 2" single-DIN receivers that let you enjoy the convenience of hands-free calling and music streaming, plus great features like multi-line displays, sound-shaping technology, built-in HD Radio™ tuners, and more. You'll need a mounting kit, of course, and it's included at a discount with most Crutchfield stereo purchases.

Unless you happen to be an exceptionally talented and experienced craftsman, you really should consult a car audio professional if you want to install a double-DIN receiver. It's important to understand that there really aren't any do-overs with this job. If you mess it up, your dash is messed up. Period.

Replacing your factory radio

To remove the factory receiver, you'll need to use the metal DIN tools that are included with your stereo purchase. Insert the tools approximately one inch into the holes in each side of the radio until you hear a click on each side. Be gentle during this process, because excessive force will damage the retaining clips. Once you've heard the magic click, spread the tools apart slightly, pull out the radio, disconnect the wiring harnesses, unplug the antenna and remove the radio.

To install your new receiver, you'll start by attaching it to the mounting bracket that's included at a discount with most Crutchfield stereo purchases. Follow the instructions that come with the kit.

Connect your Crutchfield wiring adapter (also discounted with most purchases) to the receiver, following the instructions included with the adapter. Hold the receiver assembly near the dash and connect the Crutchfield wiring adapter to the factory harness. Plug the antenna lead into the rear of the receiver; then slide the assembly into the dash until it snaps into place. It's as simple as that.

Tools needed: DIN tools

Steering wheel audio controls

If you want to keep the steering wheel audio controls in your Crown Vic or Grand Marquis, you'll need an adapter. These cars still use analog technology, so you can use adapters from either PAC or Axxess. When you enter your vehicle information and choose your new stereo, you'll be directed to the right model.

Replacing your factory speakers

The Crown Vic didn't change a lot over the years, but there were yearly tweaks and improvements that made it a better car. There were some minor adjustments made with the speakers, and we'll address them below. Overall, the process of replacing your factory speakers is relatively uncomplicated and the improvement in sound should be impressive.

Front speakers

The stock front speakers on all Fords and Mercurys were special-size 6x8 models. You can replace them with aftermarket 6x8s, or install 5-1/4" speakers with the help of the discounted mounting brackets available with your speaker purchase.

Removing and replacing the speakers is a relatively uncomplicated process, but you will have to remove the door panels. We've researched these cars extensively, so the Crutchfield MasterSheet included free with your speaker purchase will contain detailed installation instructions for your specific year, make, and model.

Tools needed: Phillips screwdriver, small flat blade screwdriver, panel tool,Torx T30 driver, 5mm socket, ratchet, and extension.

Rear speakers

The Crown Vic's rear speakers are located in the spacious rear deck. Ford took full advantage of the space and installed a set of factory 6x8 speakers back there. You can replace them with same-size aftermarket speakers, or go with 5-1/4" models mounted in brackets.

As with the front speakers, the exact technique for reaching and replacing the rear deck speakers in a Crown Vic or Grand Marquis changed a bit over the course of the production run. It's quite easy on the 2003 Grand Marquis, for example, but some later models require more work, including removing the rear seat.

There's nothing the average DIY installer can't handle, though, and no matter which year Ford or Mercury you have, you'll get help from your Crutchfield MasterSheet and, if needed, our Technical Advisors.

Tools needed: Phillips screwdriver, panel tool, 18mm socket, ratchet, and extension (varies by model).

Bass in your Crown Vic or Grand Marquis

We've seen some really trick custom audio work in Crown Vics, so whether your tastes in bass are mild or wild, you have a nice canvas to work with. The same goes for musical tastes, by the way. Adding a sub and an amp isn't just a thing for kids who love loud music. These upgrades will add depth and clarity to any type of music, from classical to country.

The Crown Vic's trunk is, as you know, a truly massive space. If you're all about power and volume, you've got a 40" W x 13" H x 25" D area that will hold a custom component enclosure and enough amplifiers to feed a big-time system.

Even if you want to retain most of your luggage capacity, you still have plenty of room for an enclosed subwoofer and a couple of amps. The more subtle option, of course, is a powered sub. You'll get surprisingly healthy performance in a compact package that will leave you plenty of room for luggage, groceries, golf clubs, and what have you.

Other options

Here are some other additions that will make your Ford or Mercury even more enjoyable to own:


Installing a security system in your Crown Vic or Grand Marquis isn't easy (security systems rarely are), but it's less complicated than it could be. If you're installing an alarm, you won't need a transponder bypass unless you're also adding remote start. 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 when it comes to security systems.

Noise damping

The Crown Vic is, and we mean this respectfully, a tank. The civilian models were made to cruise in near Lincoln-esque silence, while the more workaday Crown Vics were solidly built and reasonably quiet. Still, these are older cars, so they will tend to creak and rattle. Installing Dynamat in the doors when you're replacing the speakers can really help seal out noise and seal in sound. If you're installing a sub, lining the trunk with Dynamat will seal in the thump and keep the trunk lid from rattling, too. If you're all about sound, you might want to line the floors, as well.


Just because you can't easily install a touchscreen nav receiver in your car's dash doesn't mean you have to drive around lost. A portable GPS from Garmin, Magellan, or TomTom will mount on your dash and give you turn-by-turn directions, traffic updates, and everything you need to make your road trip go smoothly. Plus, when you get where you're going, you can put your GPS in your pocket and use it to find points of interest around town.
