In a nutshell: This article is an overview of your pickup's audio system and its upgrade options. Use our vehicle selector to find the gear that will fit your Silverado or Sierra. 

Overview of the Silverado and Sierra

The best part of driving a regular cab pickup is that when you and three friends need to go someplace, you probably won't be the one driving. The worst part is that when one of those friends has to move something somewhere, you'll definitely be getting a phone call. Then again, that might eventually lead to free pizza, so maybe it's not that bad when you think about it....

The Chevy Silverado and GMC Sierra regular cab trucks were typically more utilitarian than luxurious, but they were available with some decent (for the time) stock stereos. That said, at this point in your truck's life, the stock stuff is probably getting a bit tired. If your truck has a lot of life left in it, replacing the old gear is probably a good idea. Your friends will appreciate your new sound system while your'e heading across town with their new furniture.

Factory stereo system

Regular Cab (and Extended Cab) Silverados and Sierras were available with two different dash configurations. The lower trim level trucks have a "Type A" dash, while the mid- to upper-level trucks have a "Type B" dash.

Both configurations use the same mounting kit, which, along with an antenna adapter, is included at a deep discount with most Crutchfield stereo purchases. You'll also get our exclusive Crutchfield MasterSheet, which contains the illustrated, step-by-step instructions you'll need to install new audio gear in your truck, regardless of which dash configuration you're dealing with.

Replacing your factory radio

A variety of single-DIN (2" tall) and double-DIN (4" tall) receivers will fit in these pickups, but there are some irregularities in the dash substructure that prevent certain double-DIN radios from fitting properly. It’s best to pick a double-DIN radio with wire harnesses or RCA connectors located on the bottom half of the back of the radio, but you can also go with a number of CD receivers or digital media receivers with a depth of less than 6-1/2". A receiver with a fold-down face will not work in this truck, though, so avoid those.

To get started, enter your truck's information on our Outfit My Car page, find the receiver you want, and add it to your cart. We'll show you which mounting kit you need, and you'll receive a big discount when you purchase everything together at Crutchfield. If you have any questions, especially when you're looking for the right double-DIN receiver, one of our Crutchfield Advisors will be happy to help you make the right choice.

Detailed installation instructions

MasterSheet image
If you're looking for step-by-step instructions on how to install a car stereo or speakers in your car, there's nothing better than our exclusive Crutchfield MasterSheet™. This detailed, well-illustrated document is free with your Crutchfield order, or you can purchase one separately for $9.99.

You’ll also need to purchase an adapter that allows you to install a new stereo and still retain your warning chimes (along with OnStar functionality if you have it), plus a relay to keep your audible turn signals working with your new car stereo. These adapters are not free, but we'll give you a very nice discount on the ones you'll need for this installation.

Crutchfield strongly recommends that you use one of the recommended adapters. Failure to do so may result in serious injury or death. It will most certainly result in our (very) polite refusal to provide technical assistance when you call us for installation advice.

Tools needed: Panel tool, 7mm socket and ratchet

Steering wheel audio controls

It's relatively easy to retain the steering wheel audio controls when you install a new stereo in your pickup. 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.

Replacing your factory speakers

Door speakers

You'll need to remove the door panel to access these speakers, of course. Depending on whether your truck has manual or power windows, there will be some differences in exactly how you do that. All will be explained in your MasterSheet.

The standard factory door speakers are closest in size to an aftermarket 6-3/4" model, but you’ll need an adapter plate to install any aftermarket speaker. You can install 6-3/4" or 6-1/2" speakers and the adapter plates make installation relatively easy. The factory speakers are 4-ohm models, so you have a wide selection to choose from.

You'll need speaker harnesses to attach the new speakers to the plugs that connect to the GM factory speakers. Crutchfield includes these harnesses, plus the mounting brackets you'll need, at a deep discount with every speaker order.

Tools needed: Panel tool, 7mm & 10mm drivers, flat blade screwdriver, needle-nose pliers

Rear pillar speakers

These Regular Cab trucks have 4"x6" speakers mounted behind the rear side pillars. They can be replaced by same-size or 4" aftermarket speakers, though you'll need to re-drill the mounting screw holes no matter which size you choose. The drilling isn't any harder here than it is in your home workshop, but be smart, work carefully, and be sure to wear eye protection.

If you want to get maximum sound quality out of your new rear pillar speakers, purchase a set of foam baffles. These baffles fit snugly around the rear of the speaker to reduce rattling and improve performance. They also protect the speakers from dust and moisture, which is always a good thing in a truck. Baffles are an inexpensive addition that really makes a difference, here and in the doors.

Tools needed: Panel tool, small flat blade screwdriver, 7mm socket, ratchet and extension, Torx T-50 driver, drill with 1/8" bit

Bass in your Silverado or Sierra

There's not a lot of room for aftermarket bass in these trucks, but all is not lost. There are some small powered subwoofers that could fit back there. And if you want to power your other speakers with an aftermarket amplifier, there's space back here to mount that, too.

Shop for vehicle-specific subwoofers for your GMC Sierra

Q-Forms Kick Panel Enclosures (speaker not included) can really add to your sound.

Other upgrade options for your Silverado or Sierra

Here are some other upgrade ideas for your GM pickup:

Kick panel pods

If you really want to improve the sound in your Silverado or Sierra, install a set of Q-Forms Kick Panel Pods. These unloaded, custom-fit speaker enclosures fit into the space where your kick panels are now. They hold a set of component speakers in an ideal position, angling them to maximize sound quality. They're available in a variety of colors to match your truck's interior. Installation takes some work, but it's not beyond the realm of an experienced DIY-er.

Portable nav

If you don't want to invest in a big double-DIN receiver, you can still get the nav you need and more with a Garmin portable navigation unit. A portable GPS can be transferred from vehicle to vehicle, or just tucked into a storage compartment when not in use.

Remote start and security systems

Adding remote start capability to your vehicle lets you warm it up in the winter or cool it down in the summer. The iDatastart system is incredibly convenient and makes it easier than ever to install a remote start system, so we highly recommend it. The module requires a vehicle-specific T-harness (sold separately) to connect with your vehicle's computer, security, and ignition systems, so we ask that you call to order so that we can make sure you get the right harness for your ride.

You can also talk to your Crutchfield Advisor about a security system. They’re not as easy to install (we usually suggest letting a professional do the job), but we can help you choose a system that’ll work in your vehicle.

    Jack, There;s no shortage of speakers that will fit this truck, so you have lots of options. You can stick with Kenwood or go for something else, but almost anything will sound better than what you have! When you enter your vehicle's info into our Outfit My Car tool, you'll see which stereos fit your car, plus the correct harness. If you have any questions, our advisors are available via phone or chat.

    I recently replaced the factory radio in my 2009 Silverado regular cab. The door speakers do not work properly. They didn't work properly with the factory radio .I replaced it with a Kenwood DPX702BH.What speakers would you recommend for replacement of all 4.

    Manny, It depends on whether you have the "classic" or the new-for-2007 Silverado. If you have the new one, the standard factory door speakers are closest in size to aftermarket 6-3/4" models, but you'll need an adapter plate to install anything. You can install 6-3/4" or 6-1/2" speakers and the adapter plates make installation relatively easy. If you have the older "classic" truck, the speakers are smaller, but aftermarket replacements are available. Give us a call and we'll help you get what you need. As for the window swap, that's a little outside our area of expertise, but you can probably find plenty of info on a Silverado owners' forum.

    Hi my name is Manny and wanted to ask what are the size of speakers on the front and rear doors for a 2007 extended cab Silverado. I also would like to turn my manual windows to electric windows and wanted to see what recommendation you have about doing this.

    Elliott, If all you've done is replace the radio and battery, then there's no reason to do the Big 3 just to try and solve this problem. GM vehicles are sometimes notorious for having OEM speakers short out, so that's probably where your trouble lies. If you're good with a multimeter, then check the voltage on the stereo's power wires (the red and yellow) to make sure it stays constant, even when the sound fails. Then check each speaker to isolate the one that's causing the problem. If you purchased your gear from Crutchfield, our Tech Support team can help out.

    Upgraded my stereo to a pioneer 731x-bs, including new battery with charging system in perfect condition. However, stereo keeps turning off at high volume. Harness and radio were replaced with same result. Would you recommend "the big 3"? I'm trying to see if this is common when changing factory stereo equipment in an 08 Silverado. Seems the stereo is pulling lots of power. Any info would be greatly helpful.
