Car speakers buying guide

What to look for in full-range and component speakers

In this article: We'll cover all of the questions a first-time car audio shopper needs to answer to find great car speakers. Questions like:

  • Which speakers will fit my car?
  • How much power do my speakers need?
  • Should I go with full-range or components?

And we'll introduce you to our online shopping tools that make the process easier.

There are many ways to add new life to your music in the car, but new speakers offers one of the fastest and most cost-effective ways to upgrade your sound. We have what you need, whether you just want to replace your factory speakers or if you plan to install an amplifier and need speakers that can handle a lot of power.

Shopping for car speakers can be confusing, so we try to make the process as straightforward as possible. Watch the video below for an overview on how to shop for new car speakers.

Crutchfield makes it easy to shop for car speakers

The first thing you'll need to do is use our vehicle selector to tell us what you drive. We'll ask a few questions and then show you the best options for your vehicle.

The Crutchfield car speaker recommender

Once you've told us what you drive, you'll find the car speaker recommender at the top of the car speakers category page.

The recommender is a great tool that could land you the perfect set of speakers in minutes.

specific options

That's HOW to shop for new speakers. Next we'll explain WHAT you need to know to make the best choices.

How many car speakers do I need?

There's no standard for the number of car speakers that are factory-installed in a vehicle. In fact, they seem to get more numerous every year as car makers introduce premium factory sound systems with perks like noise cancellation and simulated engine noise. But for this article, we'll stick to the basics.

When replacing front and rear speakers, a good goal is to have a voice-matched system. That means having the same brand and series of speakers in the front and rear. If you're on a budget, that doesn't have to happen all at once. Focus on your front speakers first. When you're ready, update the rear with speakers from the same speaker series (or at least, the same brand) for consistent sound characteristics.

Speakers for the front of your vehicle

Some vehicles only have two speakers in the front, one per door. They use a full-range design. Other vehicles feature four speakers in the front, two per side. This is typically woofers in the door and a tweeter either higher up in the door or in the corner pillar or dash.

Many vehicles also have a center dash speaker, which typically handles vehicle essentials like door chimes and navigation prompts, in addition to playing music. Many people opt to leave the original speaker in this spot.

Speakers for the rear of your vehicle

Rear door speakers, rear deck speakers, and tailgate speakers are often full-range, although components have become increasingly popular. Rear speakers provide sound to backseat passengers and "rear fill" for the front row. Rear speakers generally don't make a significant contribution to the sound experience in the front seats. As a result they can be less important to drivers who don't have passengers very often or to sound enthusiasts who don't want any interference with their front soundstage.

speaker measurements

What size speakers should I buy?

It's easy to feel overwhelmed by a long list of car speakers, all with different sizes. The good news is you don't have to sweat speaker size too much once you've told us what vehicle you're shopping for and whether you're shopping for front or rear speakers (or both).

Sometimes you'll have a choice of a couple speaker sizes for a given location. In that case our rule of thumb is, "the bigger the better." So, given the choice between a 5-1/4" using a bracket or a 6"x9", we'll usually say go with the 6"x9" for more oomph.

The finer points of fitting car speakers

When looking at speaker fit, we're not just talking about the diameter of the speaker opening. We're also considering the allowable depth of that opening, sufficient room for the tweeter in front of the speaker, and several other factors. You can learn more about the details in our article about understanding speaker sizes. If speaker brackets are required to install your speakers, we'll include them.

Full-range vs. components — what type of speakers should I get?

Aftermarket car speakers can be divided into two main categories: full-range speakers and component speaker systems. Let's take a look at each.

Full-range speakers

Full-range speakers contain all the speaker elements in one basket. In their simplest form, they consist of a woofer for the lows, and a tweeter mounted onto the woofer to produce the highs. Some models will have additional drivers, like a midrange and/or supertweeter – these are referred to as "3-way" or "4-way" speakers.

You should choose full-range speakers if you're looking to replace factory speakers with minimal effort. In most cases, you simply remove the old speaker, connect the new speaker with a free Crutchfield wiring harness, and mount it. You'll find full-range speakers at nearly every price point and power range.

Component speakers

Component speaker systems use a superior speaker design to give you the best possible sound. A typical component system includes separate woofers, tweeters, and external crossovers.

External crossover networks are often included with component speaker sets.

In a component system, the tweeter is separated from the woofer so that it can be mounted higher up in the car. If your car has factory tweeters, you can usually mount the new one in that location.

The external crossover network in a component system uses high-quality components to ensure a sharp delineation between the frequencies sent to the woofer and tweeter. Your music will sound more realistic, more "live," and have greater depth.

How much power do my new speakers need?

Car speakers convert power into sound waves. Different car speakers work better with certain power sources. Factory stereos mostly deliver lower power; aftermarket stereos offer a bit more; and aftermarket amplifiers provide the most power possible. The more power you use, the more loudness and musical detail you get, but you want to make sure your speakers can play accurately while playing loudly. So, here are the two main specifications to consider, depending on your power source...

Car speaker sensitivity explained

Sensitivity measures how much sound a speaker yields from the power applied to it. If you have a low-powered factory stereo (typically 10-15 watts RMS per channel or less), speakers with high sensitivity ratings (over 90 dB) will make the best match.

If you have a high-power system like an aftermarket stereo or external amplifier, then consider speakers with lower sensitivity ratings. Properly powered, they'll provide excellent sound quality.

Car speaker power handling explained

Power handling lets you know how much power (measured in watts) a speaker can handle. If you have a low-powered system, your speakers don't need to be able to handle lots of power. On the other hand, a system with powerful external amps will require speakers whose power handling is close to the output of the amps.

Important note: The key spec in power handling is the maximum RMS power-handling, not the peak power handling. RMS ratings realistically measure how much power the speaker can handle on a continuous basis, not just for a short period of time. A speaker rated at "up to 50 watts RMS" will make a better match for your low-powered stereo than another speaker rated "10-80 watts RMS."

What does that mean for you?

  • If you're using a factory system for power, look for new speakers with low RMS wattage and sensitivity of 90dB or higher.
  • If you're using just an aftermarket stereo for power, look for speakers with power-handling no higher than 75 watts RMS.
  • If you're using an aftermarket amp for power, you'll want to match RMS power-handling to the specs provided in your amp's manual.

How much should I spend on car speakers?

If you're unsure how much to spend, consider your expectations for sound and how long you intend to keep your vehicle.

  • If you're just looking for a step up from factory sound in a vehicle you plan to trade in a few years, entry- to mid-level speakers are a solid option.
  • If you're planning to keep your car for a while, and possibly build a system over time, it's not a bad idea to invest in a premium set of speakers.

Generally, as you step up in cost, you're stepping up quality of design and materials. Better design makes more efficient use of power when converting energy to sound. Better materials ensure better sound quality and long-lasting durability.

Elements of car speaker design

Woofer materials

Factory speaker cones are typically made of paper, which degrades over time. Aftermarket speaker cones are made of durable materials that are stiff, yet lightweight. They're designed to move easily yet retain their shape for more accurate sound production.

Tweeter materials

A tweeter's material and design have a big effect on the type of sound it produces. Generally, tweeters made of soft materials like poly, textile blends, or silk will give you sound that's refined and somewhat mellow. If you like the highs bright and snappy, go with hard materials, like metal or graphite.

tweeter material

Surround materials

The surround on a woofer performs a vital role — it allows the woofer cone to move freely and emit bolder bass. It must be durable to stand up to temperature and humidity extremes. Surrounds made of rubber will provide the best overall performance and longevity. Foam and cloth surrounds cost less, yet still perform well.

This subwoofer photo perfectly shows how the surround attaches the speaker cone to the metal frame. The surround keeps the cone centered as it moves back and forth.

Pivoting or swiveling tweeters

If you're replacing speakers low in your door, full-range speakers with pivoting tweeters can have a big effect on your sound. Tweeters produce very directional high-frequencies, so pivoting tweeters can be "aimed" towards the listener for a higher soundstage. Your music will sound more realistic with a greater sense of depth.

pivoting tweeter

Tweeter attenuation

You'll often see crossovers that provide switchable levels of tweeter attenuation. After testing your new speakers, you may discover that your highs sound too loud in the mix. Tweeter attenuation allows you to adjust the tweeters to your vehicle layout and preference.

Bi-amping capability

Some crossovers have extra input terminals to allow bi-amping. Instead of driving the woofer and tweeter with a single channel of amplification, you actually connect two sets of wires, with each set carrying the power from a separate amplifier (or amp channel). This way, the woofers and tweeters receive dedicated amplification. Look for this feature if you're planning to put together a serious high-performance system.

    Well, after this comprehensive, excellent article, (which I read first!) you are now clued up and may want to hear about MY budget solution for MY car as it's slightly offbeat. I bought a Nissan and it came with excellent factory Coaxials if only 40W and made of paper. Turns out all I had to do was add an under-seat 4 ch amp and a Sub and I'd have been ecstatic! Instead, I tried out 3 sets of component speakers in the $70 - 100 range and ALL fell short! So, with the little under-seat Amp and Active Sub in place, I put back the factory Coaxials and WOW!! This IS breaking the rules but it sounds magnificent! So, I'm now getting 2 pairs of Polk Audio DB652s tomorrow, fitting them day after and voila! I'm set! Assuming they sound better than my factory all-in-ones! Point being, once you know the rules, you can experiment and who knows! Why not an under-seat Amp and Active Sub with 4 Coaxials?! Of course you'd need to match them but here at Crutchfield, you not only get those parts at ALL levels, they'll even help you match them! Bottom line, in MY experience, cheap 'Components' are NOT a great option. Infinity and JBL are good in this price range but not the high end brands. And hello, why not a high end under-seat Amp and Sub?! With high-end Coaxials! These Coaxials are made by experts... I certainly cannot do better with a 'Woofer' (Mid-bass) and a tweeter than the dudes at say, JBL... THAT IS WHAT THEY DO!! And trust me, a Sub is a MUST!! Amp too!!And THIS is the place to buy.

    Sean, not necessary at all, and depending on your factory speaker openings, probably a more straight-forward installation.

    Any tips to make door speakers last longer? Put new speakers in the front doors of a 2004 F-250 a year ago and the driver side speaker is not working again. I live in western Washington, wondering if moisture is part of the problem.

    I was wondering if its possible or smart to run 2 different Ohm rating speakers on a 5 channel amp. 2 component Infinity kappa 60csx@2.5ohm And 2 component infinity reference 6530cx @ 3ohms. Or should I stick to the same resistance. Running on a 5 channel pioneer. Is rated for 4x75RMS @4ohm 4x100 RMS @ 2ohms.

    Ok so I was gonna get the Kenwood KMM-BT328U as my stereo and that's like 90 bucks and I'm looking to spend around 250 bucks. The Speakers in the Front doors and its the back window are 6x9 what would be the best for me. I would rather not do an amp unless it will actually make it sound that much better. My car is 2003 Toyota Camry BTW.

    Hai, Iam having Sony WX-GT88UI as my head unit, with 2 coaxial speakers on my front door panel. Now I want to upgrade the front door speaker with component speaker. Can you suggest the spec for component speaker compatabile with the above sony xplod model head unit. Presently i am not going for adding an amplifier. Regards , Arun

    Arun, your head unit puts out about 20 watts RMS per channel. If you'd like to add components, look for sets with high sensitivity, around 90 dB and above.
