In a Nutshell

This article discusses how to install car audio gear in your Suzuki SX4. Check it out and then use our vehicle selector to find audio gear that will fit your vehicle.

The stock receivers aren't that bad, really, so if you're upgrading your stereo in stages, start with the speakers. The factory models are pretty weak, so you'll see an immediate improvement in sound quality.

 A new receiver will bring out the best in those new speakers, of course, but you'll also be able to add improved functionality and connectivity. If you want bigger bass, you can replace the stock sub or go big with a subwoofer enclosure. A compact powered sub is also a good option for this rugged little car.

Full Story

Overview of the Suzuki SX4

It's never a good thing when the company that built your car announces that it's going to stop selling cars in your country. Just ask a Suzuki SX4 owner. One day you're driving around in a neat little car, the next day you're checking to see if the AMC people will let you join them in the "Orphan Cars" section at the local show n' shine.

The good news is that Suzuki is a multi-national manufacturing behemoth that still sells tons of motorcycles, ATVs, and more in North America, so it's not like they tossed the keys on the floor and blew town. Suzuki still sells cars all around the world, too, so parts are still available.

The better news is that Suzuki left behind some pretty nifty cars, like the SX4 hatchback (shown) and sedan. If you have the front-wheel drive version, you've got a fun little everyday runabout. With the available all-wheel drive, you get all that good stuff, plus the ability to get home in a blizzard. These cars reviewed well when new, and they seem to be aging nicely. Replacing that tired old factory stereo system with a new receiver and speakers will make your Suzuki even more fun to drive.

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 SX4, 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.

Factory stereo system

The SX4 is a pretty basic little car, but the stock stereos still offered a lot for the money. The standard AM/FM/CD/MP3/WMA receiver was XM-ready, and it pumped all that music through four rather puny speakers. The optional Premium system upgraded to a 6-CD changer and nine speakers, including a subwoofer, which is a lot better. A Garmin navigation system was available towards the end of the line.

A variety of single-DIN (2" tall) and double-DIN (4" tall) receivers will fit in the SX4, so you have lots of options. When you replace the factory radio, you'll lose the factory AUX input connection, factory XM satellite radio, and/or factory nav, but all those features can be replaced (and improved upon) when you install an aftermarket receiver.

Replacing your factory radio

Despite some mid-cycle changes to the dashboard as a whole, the stereo mount stayed the same, so the same dash kit will work in all SX4s, regardless of the car's age or what size stereo you're installing. This kit, along with a wiring harness designed to connect your new stereo to the factory wiring, is included at a deep discount with your Crutchfield order. You'll also get a free Crutchfield MasterSheet, which contains illustrated, step-by-step disassembly instructions.

Installing a new stereo in your SX4 is a rather uncomplicated task. To remove the old one, start at the bottom edge of the radio side trim panels and pry them out. Once the panels are out of the way, remove the four Phillips screws that secure the factory radio in place, pull it out, disconnect the harnesses, and remove it from the car.

Secure your new receiver to the mounting bracket following the instructions supplied with the dash kit, then use the Crutchfield-supplied wiring harness to connect the receiver to the factory wiring and plug in the antenna lead. From there, slide the receiver into place and secure it using the screws you removed earlier. Test it out to make sure your stereo is working properly. If it is, put the dash back together.

Tools needed: Phillips screwdriver, small flat blade screwdriver, panel tool

Steering wheel audio controls

It's relatively easy to retain your Suzuki's steering wheel audio controls 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.

Replacing your factory speakers

The SX4's standard stereo system featured speakers in the front and rear doors. The "Premium" package added tweeters and a subwoofer.

Front door woofers

The factory 6-3/4" speakers can be replaced with same-size, 6-1/2", or 5-1/4" aftermarket models. You'll need mounting brackets to install the smaller ones, and Crutchfield includes them with your speaker purchase.

You'll need to drill new holes for the mounting screws regardless of which speaker size you choose. This isn't massively challenging for the average DIY-er, but any time you're drilling holes in a car, it's smart to take your time and work carefully. Make sure you're aware of what's around and behind the area you're drilling into, and always wear eye protection when you're running a drill bit into metal. Sure, you might look cool and mysterious with an eye patch, but why find out the hard way?

Some aftermarket speakers include mounting screws, but others do not. Check the box before you start working, because going to the hardware store in the middle of a project isn't a whole lot of fun.

Replacing the speakers starts with removing the door panels, and that's a reasonably simple task that's covered in the illustrated, step-by-step Crutchfield MasterSheet disassembly instructions included with your Crutchfield stereo or speaker purchase.

Tools needed: Phillips screwdriver, small flat blade screwdriver

Front door tweeters

If you've removed the door panels to get to the woofer, you've already gotten to the 4-ohm factory tweeters, which are attached to the panel itself with a pair of Phillips screws.

You'll need to fabricate a mounting bracket or use a set of our universal backstraps to mount them, and you'll also want to use Posi-Products connectors to hook them into the factory wiring. You'll need to remove the factory tweeter grilles in most cases. Flush mounting is possible only if the overall diameter of the aftermarket tweeter is less than 1.224".

Tools needed: Panel tool, Phillips screwdriver

Replacing the rear door woofers is basically the same process as replacing the ones up front. We'd go through the whole thing again, but you get the point, so why bore you with repetitive copy?

Bass in your Suzuki SX4

The SX4's "Premium" system already includes a small subwoofer, so you can replace that or go bigger with a compact powered subwoofer or a big, thumping sub enclosure. Interestingly enough, the hatchback and sedan offer the same amount of space for an enclosure. You'll have a 40" W x 20" H x 26"/14" D space to work with in either case, so you can create something interesting if you want to go big on bass.

The factory subwoofer is a 3-1/2" dual voice coil unit that can be found in a box under the driver's seat. It only receives bass frequencies from the factory amp. To replace it, you'll need to scoot the seat as far forward as possible to get to the enclosure, but you won't have to remove the seat. Pry the harness clip out of the sub enclosure bracket, then remove the four 10mm bolts that secure the enclosure to the floor. Once that's done, disconnect the harness and remove the enclosure.

Place the enclosure on your workbench, then remove sixteen Phillips screws securing the bracket and the bottom plate and remove both. Remove the four Phillips screws securing the speaker to the enclosure, then disconnect the harnesses and remove the speaker. Your new sub will only need two screws to hold it in place.

Tools needed: Panel tool, Phillips screwdriver, 10mm socket, ratchet and extension

Other options for your SX4

There are all sorts of neat ways to improve your SX4's sound and everyday usefulness. Here are a few ideas:

Dynamat

Dynamat 10435 Xtreme Door Kit

Dynamat

The SX4 is a well-built car, but it’s still a subcompact, so it can get a bit buzzy at highway speeds. The Dynamat Xtreme Door Kit is the perfect way to seal out the noise and seal in the sound. This heavy-duty insulating material is easy to install, and it really makes a difference. This is a great thing to do while you’re installing new speakers. Why take the doors apart twice if you don’t have to? One kit will take care of the front doors on your SX4.

iPod® and satellite radio adapters

Better sound is a wonderful thing, but not everyone is up for replacing the factory receiver. Not a problem. You can still add versatility and great sound to your SX4. We offer several adapters that will allow you to use an iPod, MP3 player, or satellite radio with the factory system. You can upgrade the speakers later for even better sound.

Security

Installing a security system in your SX4 isn't easy (security systems rarely are), but it's not insanely complicated, either. Our Crutchfield Advisors can help figure out what you need to get the job done, but we usually suggest turning this kind of work over to a professional.
