Car stereo buying guide
Tips for choosing a new stereo for your car

The car stereo is the centerpiece of any car audio system. They look great in the dash and are full of useful features. Also known as a radio, receiver, or head unit, today's car stereo performs a variety of complex functions so that we can better enjoy our drive time. To understand these functions, it's helpful to think of a car stereo as having three different sections:
- Source — This is the part that let's us choose what we want to hear. Sources may include a standard AM/FM tuner, CD or DVD player, satellite radio, iPod® or smartphone, or a USB input.
- Preamp — This is where all sound adjustments are made. The preamp section includes controls ranging from simple volume, balance, fader, source selection, and tone adjustments to sophisticated crossovers, equalizers, and time correction.
- Amplifier — The amplifier section boosts the small (low-voltage) audio signal coming from the preamp section into a larger (high-voltage) audio signal that's sent out to the speakers.
Why would I want or need a new car stereo?
A new stereo will give you better sound and more playback options than the typical factory stereo.
Better sound quality
Superior built-in power and better circuit design mean that an aftermarket car stereo isn't just louder than the typical factory stereo, it also produces cleaner, richer, more-detailed sound. Enhanced tone controls in the preamp section mean that you can do a better job fine-tuning the music.
New sources for music and added functions
One of most common reasons to get a new stereo is to expand your system's music playback and other capabilities. Aftermarket stereos offer advanced capabilities, such as:
- MP3/WMA/AAC playback
- iPod® and iPhone® support
- Support for Android™ phones
- Satellite radio
- DVD playback
- Bluetooth® connectivity
- GPS navigation
- Support for Pandora® Internet radio and other app-related sources
In particular, being able to use smartphone apps in the car is a big reason to get a new stereo.
Other things to consider when purchasing a new car stereo
Getting the right listening sources is only one thing to consider. You'll also want to keep in mind some of these aspects of a new reciever.
How sophisticated do you want to get?
Advanced features on new stereos more detailed displays to make it easier to see what you're doing. You should certainly consider a touchscreen monitor. They make it much easier to control and adjust the stereo.
Better sound controls
Speaking of adjustments, precision sound controls like digital time correction and parametric equalization are available on higher-end receivers for those of you who really want to tweak the sound. But even lower-priced aftermarket stereos will offer more audio control that the typical factory radio. That's just one more way a new stereo can make your music sound better.
Cool cosmetics
Aftermarket car stereos, with their high-tech displays and cutting-edge layouts, can enhance the appearance of your car's interior. Your options include full-color animated displays, customizable color schemes, and again, touchscreen monitors which usually have selectable backgrounds and colors. If you want to heighten the listening experience, look for a stereo with lighting that flashes to the beat!
Expandability
Auxiliary inputs, USB connections, and audio/video outputs let you expand your system by connecting portable music players, rear seat video screens, external amplifiers, and powered subwoofers to your new stereo. At the very least, look for a new stereo that has either a USB input or Bluetooth capability so that you can add your favorite listening source.
Security
Features like detachable face plates and security codes help protect your investment from theft.

Posted on 10/27/2019I wouldn't recommend buying anything from Cutchfield unless you just want to listen to a radio. As I just found out with my 2010 Corolla and the Pioneer AVH-501EX. Nothing but the radio works without a parking brake wire being connected and I mean nothing. No Bluetooth, no dvd, no apps even connected USB. Nothing. To connect to said wire, I would have to risk breaking another wire, to remove the connector. In Crutchfield's defense, their tech told me where the wire is and wished me luck but after removing the necessary panels, i erred on the side of discretion and reinstalled the panels. Yes, you can buy a bypass or install a relay to get around said elephant in the room but you'd be better off buying from a local installer and letting them take the risk. I definitely wouldn't recommend anything from Pioneer. The manual they send is absolute garbage. Outside of finding some of the inputs on your unit, you won't find any other information regarding the unit you purchase. I'm highly disappointed. Sure I'll get the work around or take it to a local shop but I shouldn't have to do that for some idiotic interlock. Don't care about the DVD's but I should be able to connect a phone and I can't do that.
Robert Ferency-Viars from Crutchfield on 10/28/2019Doug, I understand your frustration and reluctance. We all have our limits and comfort levels when it comes to DIY projects, and we often don't know where those limits are until we run into them. While I have installed many a car stereo and even built my own deck in the back yard, my plumber is very grateful for my reluctance to turn a pipe wrench. Installing a new car stereo definitely requires connecting a lot of wires, most of which involves wiring between the stereo and installation adapter (we created our ReadyHarness service to remove as much of that work and worry as we can and simplify installation as much as possible). But some connections have to be hard-wired to the car, especially if the new stereo has a video screen. Most of the time, the wire splicing can be done safely and securely by using a common wire tap or Posi-Tap connecter with no cutting needed. But if you're not comfortable doing it, then yes, turn to a professional installer for help.john smith from alaska
Posted on 9/19/2017All most people seem to want from a car stereo is volume and bass. Far too many systems in cars are about quantity, not quality, although as 405line has said, going for high quality is rather pointless in a car anyway. I imagine the Mark Levinson systems in a Lexus LS is about as good as it gets, but haven't tried one.

Posted on 1/8/2017I have 2 15" MTX Thunder6000 and a 1000 watt Sony Xplod 2/1 channel amp will that be enough power for both subs?

Posted on 12/5/2016I have a Pioneer HU which has 5-6 volts on all the rca amp pre's and was wondering do I need to make sure on amps if they can accept that high of volts off the rca plugs for the amps?
