In a Nutshell

This article will explain how to install new car stereo gear in your truck. Replacing the old radio isn't hard, and you have plenty of options for an aftermarket receiver. You might want to spend a little more to get one that you can grow with. Look for things like preamp outputs, Bluetooth® functionality, multi-phone pairing, etc.

Replacing the front and rear door speakers is also pretty simple, and you have a nice variety of options to choose from. You can also expand your system with some amps and a subwoofer

The custom-made enclosures for this truck are amazing — they tuck out of the way, and some come pre-loaded with some of the best subs on the market. You can use our vehicle selector to find the gear that will fit your truck.

Full Story

Overview of the Chevy Silverado/GMC Sierra Extended Cab

The Chevy Silverado and GMC Sierra have always been workhorses, so it's not exactly a surprise to see a lot of these older trucks out on the road and getting the job done. They're tougher than cheap beef, parts are easy to find, and, at this point, any '99-'02 model will have plenty of that "old truck" character.

Old trucks are cool, but old factory stereos are pretty weak. If your pickup is still hauling after all these years, it's past time for an upgrade. Smartphone compatibility, satellite radio, and Bluetooth® are just a few of the modern features that can make your Silverado or Sierra a much better place to work and play.

Note: The chassis discussed here, known inside GM as the GMT800 and to the rest of the world as the Chevy Silverado and GMC Sierra, was introduced in1999. The previous generation, the GMT400, hung around for another year as the "Classic" model. If you're not sure which '99 version you have, check these exterior photos to see which one looks like your truck. The Classic has a flatter hood and a much more squared-off front end.

This article is an overview of your vehicle's audio system and its upgrade options. Looking for step-by-step instructions on installing a car stereo or speakers in your Silverado? We'll include a Crutchfield MasterSheet™ free with your Crutchfield order, or you can purchase one for $9.99.

Factory stereo

Replacing your factory radio

The '99-'02 Silverado/Sierra twins were equipped with the standard GM corporate AM/FM CD player, which is slightly taller and shallower than most single-DIN aftermarket stereos.

A vast number of single-DIN (2" tall) and double-DIN (4" tall) stereos will fit right in, with the help of dash kits that are designed specifically for your truck. The single-DIN fits into your existing dash, while the double-DIN kit is actually a replacement dash panel. You'll also need an antenna adapter and a wiring harness adapter that will allow you to connect the new radio without having to cut into the factory wiring All of those items are available at a healthy discount with your order, and you'll also get a free Crutchfield MasterSheet, which contains illustrated, step-by-step instructions on how to install a new stereo and speakers in your truck.

These trucks offered an analog version of OnStar® which is no longer supported, so that won't be an issue when replacing your radio. The column-mounted shifter, however, might be. A receiver with a flip-out screen probably isn’t a good idea in this truck because the screen will hit the gearshift when it opens.  To see all the receivers (and other gear) that fit, enter your vehicle info in our OutfitMyCar tool.

Tools needed: Panel tool, 7mm socket, ratchet, and extension

Steering wheel audio controls

Not all Silverados and Sierras were equipped with steering wheel audio controls, but if yours was, it's relatively easy to retain this convenient feature when you install a new stereo. When you enter your vehicle information, our database will choose the adapter you need to make your factory steering wheel controls work with your new receiver — and we'll give you a nice discount on it, too, when you buy it with your new stereo.

Replacing your factory speakers

Depending on the model, your truck will have factory speakers in the front doors and the rear doors.

Front doors

Stock speakers for the front of the Silverado/Sierra are 6-1/2", a common size with great aftermarket support. You won’t have trouble finding a speaker to fit any musical taste or budget. You can install a 6-1/2" or 5-1/4" speaker using a simple adapter plate for easy installation, and you can also install the slightly larger 6-3/4" speaker if you’re willing to drill some new screw holes.

You’ll need wiring harnesses to connect your new speakers. They'll allow you to attach the new speakers to the plugs that connect to the GM factory speakers, and they make it easier to reinstall the factory speakers if you ever sell your truck. Crutchfield gives you a nice discount on mounting brackets and speaker wiring harnesses with every speaker order.

In trucks equipped with the 6-speaker system, the tweeters are mounted above the front door speaker. (Crutchfield Research Photo)

An optional 6-speaker stereo system included tweeters in the front doors. These speakers are also easy to remove, and offer a handy mounting spot should you want to add aftermarket units. You’ll have to fashion a mounting plate for the new tweeter, or use our universal backstraps (or silicone or hot glue) to secure them in the doors.

Tools needed: Panel tool, 7mm socket, ratchet, and extension

Rear doors/side panels

Extended Cab modelsl were available with three or four doors. Either way, the speakers are easy to reach and replace, though you will need to drill new holes for the mounting screws.

A lot of GM vehicles use 4"x6" speakers, and this truck is no exception. You'll find 4"x6" speakers in the rear doors in the 4-door Extended Cab, or in the rear door and side panel of the 3-door version. Once you’ve removed the body panels to get to these speakers, they’re extremely easy to remove, thanks to their clip-in plates.

You have plenty of aftermarket options for upgrading these speakers, including 4"x6" plate speakers, as well as 3-1/2" or 4" speakers which will fit using inexpensive adapter plates. When you're drilling the new screw holes, make sure you know what's behind and around the drilling area, work carefully, and wear eye protection.

Tools needed: Panel tool, 7mm socket, ratchet, and extension, cordless drill

Bass in your Silverado or Sierra

You’ll find an amazing number of subwoofer options for every body style of this popular truck. If you want bass, you should be able to find an enclosure that meets your needs.

You'll find that custom enclosures, like the JL Audio Stealthbox above or an MTX Thunderform enclosure, are the best way to add bass without giving up valuable interior space. These custom boxes are built to fit in out-of-the-way places and still let you get the big bass that only 10" or 12" subwoofers can provide.

Make sure you feed them enough power to really let them achieve their full potential. If you need help figuring out the specs involved in pairing them with an amp, read our helpful article about matching amps and subwoofers

If you're looking for a quicker and easier bass solution, a powered subwoofer will give you plenty of low-end thump from a compact package.

Other options for your Silverado or Sierra

There are plenty of other ways to improve your truck's sound. Here are some of the ways we can help.

Amps

Like most pickup trucks, the Silverado/Sierra has a noisy cabin. If you really want to hear your music without taxing your speakers, add an amplifier. There are plenty of inexpensive options that will give you the ability to hear your music loud and clear, especially when paired with some upgraded speakers and some Dynamat in your doors. Mounting options abound, but the best place for an amp is under the front or rear seats.

Navigation

These trucks weren't available with factory navigation, but you can add an aftermarket double-DIN nav receiver with help from a dash kit. Depending on how you use your truck, a portable navigation unit could also be a good solution, because you can move it between vehicles as needed and tuck it into a storage compartment when you're not using it.

Security

Installing a security system in your truck isn't easy (security systems rarely are), but it's less complicated than it could be. 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.

    Will a flip down screen player work in the 01 chevrolet

  • Jon Paulette from Crutchfield

    Posted on 7/13/2015

    Robert, A receiver with a flip-down face will not work in this truck. On the upside, there are plenty of single-DIN receivers that will work just fine.

    Thank you, what about one of the small screen single din units

  • Jon Paulette from Crutchfield

    Robert, A single-DIN should fit just fine. To be sure, though, use our vehicle selector to confirm which stereos fit your truck.

  • Jon Paulette from Crutchfield

    Posted on 9/8/2015

    I have an 02' Silverado extended cab with the 6 speaker option. So I am leaning towards purchasing a component speaker bundle. But I am unsure of where to put the crossover and the tweeter? I am a novice so doing this makes me nervous. Drilling does not scare me its the WIRING aspect.

  • Jon Paulette from Crutchfield

    Posted on 3/20/2016

    Dan, That sounds like a smart plan. Wiring can be challenging, but when you buy your gear from Crutchfield, you can always call Tech Support for free advice about your system.

    I have a 1997 chevy silverado ext cab 3rd door. My question question is what speakers are in the rear cab. Door has a speaker with tweeter. The 3rd door doesn't have a in door speaker,but one in each corner of the cab. It's a 97,which was probably produced in 96. And also the cd player has a cassette player built in,with the cd player located further down. Any help with specs,etc. Would help me in finding suitable replacement for cardboard speaks,etc. Thanks.

    hey I have a older iva-d310 alpine. I got it installed so it doesn't hit the shifter but where is the best place to put the controller box for the head unit? was thinking either behind the seat or under but I am worried about overheating under the seat. opinions?

  • Jon Paulette from Crutchfield

    Posted on 6/27/2017

    Thomas, Nice piece of installing, there! The tuner is designed to be stashed out of sight, so it should be fine under the seat or wherever else you can make it fit.
