What does as mean on a car radio

June 9, by Stereo Depot. When it comes to a car stereo systemit can be tough to know what to look for. Most speakers and amplifiers have a number of watts attached to it, so when it comes time to purchase a new car stereo system, it is important to have at least some understanding of what that number signifies.

In most cases, the amplifier is what supplies the power needed for this work, so watt measurements are usually in reference to the car stereo amplifier. Since a car stereo system blasts sound into a confined area, watts in a car stereo system are of less importance than in a bigger space. In fact, unless you really like to bump your music as you are driving around San Diego, a high wattage does not matter as much as you may think. At the average listening level, 1 watt is actually enough power for your car speakers.

Therefore, if you do not intend to pump up the volume, a low wattage amplifier and car stereo system should work great for you. If you like to crank the volume, avoid having a low watt amplifier. If you have a low-powered amplifier and turn the volume up very loud, your sound quality will suffer.

The sound will be distorted and clipped, and you will also be in danger of blowing out your speakers. That is why it is essential to talk to an expert about your car stereo needs, as they can prescribe the perfect amplifier and car audio system for you. In general, a watt receiver or amplifier should suffice, but it is better to be safe than sorry.

Many systems today can play music from a staggering array of audio sources: radio, CD, portable music players like the iPod, USB flash drives, SD cards, Bluetooth audio and hard-disk drives. The overwhelming number of audio choices can make the average consumer's head spin. This five-part series, "Understanding Car Audio Systems," will give you a grasp on the basics of today's multifaceted "infotainment" systems.

In recent years, automakers have really stepped up their game with their original equipment manufacturer OEM systems. But no matter how complex it is, every car audio system consists of three main components.

The first is the radio or "head unit" that controls the entire system and generates the audio signal. The second is an amplifier that increases the strength of the audio signal so that it can drive the third component, the speakers that reproduce the sound. The Head Unit A high-end home audio system uses separate electronic components — a radio tuner, CD player, preamp, amplifier — connected by various cables.

Since space is at a premium in a vehicle, automakers have to cram as many of these components as possible into one device: the head unit. Because of this, the head unit performs multiple duties, but its two main functions are controlling the overall system volume and the various audio sources in a vehicle. When you look back at automotive history, AM radio was the only audio source in a car for years. Then came FM and tape formats such as 8-track and cassette. A CD player is now standard in most vehicles, and many factory head units can also receive satellite radio from the subscription services Sirius or XM.

Head units can also be used to control media players like the iPod or navigate the content of a USB flash drive that's connected to the stereo system. Head units with Bluetooth audio can also play music that's streamed wirelessly from a compatible mobile phone. In addition to controlling the system's volume, head units usually include basic tone controls such as bass and treble to tailor the sound to the listener's taste.

Many audio systems also include signal processing that automatically adjusts the volume, depending on the ambient noise in a moving vehicle. Some high-end OEM audio systems also have a separate subwoofer and subwoofer-level controls. The Amplifier A car stereo system has to have an amplifier to increase the power of an audio signal so it's strong enough to move the speakers and create sound. Amplification is a two-stage process handled by a preamp and a power amplifier. The preamp is usually housed inside the head unit and takes data from a radio, CD player or other audio source and prepares it for the power amplifier.

This process includes slightly boosting the audio signal, which makes it compatible with the input of the power amplifier and ensures that it's resistant to noise that can radiate from other electronics in a vehicle. The power amplifier then takes the preamp's low-level signal and significantly boosts it so it can move the speakers and create sound.

Many head units have a small, built-in low-power amplifier that can "drive" smaller speakers. This allows the audio system to be reduced to just a head unit and a few speakers. But better sound requires more power. So higher-end systems have separate power amplifiers that are mounted away from the head unit due to their size and the heat they generate.

We cover the details of "outboard" amplifiers in a separate article in this series.Joinsubscribers and get a daily digest of news, geek trivia, and our feature articles. These days, more and more people turn to their phones for GPS and music in their car. Google Maps is way better than whatever lame system is built into your vehicle. Enter Android Auto: the best of what your phone offers, but built in to the head unit of your dash.

It has a home screen, integrated Google Maps, and support for a slew of audio applications. It also uses voice control for essentially everything, so you can keep your eyes on the road. Just like Android Wear is an Android companion you wear on your wrist, Auto is a companion that goes in the car.

Android Auto comes in three forms. You can either buy a car that has Android Auto built-in as many models dopurchase an aftermarket head unit and have it installed, or use the app version on your phone.

The first method is, of course, the easiest and arguably best way to use Android Auto. A new head unit is a much more practical, though still fairly pricey, option.

As announced by Google in earlyAndroid Auto has made its way to phones. While the experience is very similar to that of a head unit, there are definitely some notable differences too. For all the head unit options, the core of Android Auto is the same. Much like Android Wear, Auto has an app that runs on the smartphonewhich does all the heavy lifting for you. As soon as you install the app and plug the phone into an Auto unit, it pairs the smartphone over Bluetooth and handles everything else over the USB connection—very little is required of the user to get started.

From this point forward, it will be rendered essentially useless—Auto will force itself into the foreground of the phone, removing access to all controls aside from Home and Back. The idea is to keep your eyes off your phone while driving. Telling it to navigate to certain places has gone off without a hitch every time for me, and it has been a great experience. I got my head unit installed just before vacation, so I used navigation a lot during that time. The biggest issue I ran into was with voice control.

Sometimes it worked well, other times it had trouble understanding what I wanted. But if you are installing Android Auto into your existing car, things get pricey quickly. For example, most Auto head units have significantly larger displays than even the biggest Android phones. As far as interface is concerned, the Auto phone experience is pretty similar to that of a head unit, though the layout is slightly different. I mean, there are lives at stake out there, so playing with your phone while driving is something that you should absolutely not be doing, under any circumstances.

Fortunately, Auto running on the phone makes this much easier to avoid. The controls are at the bottom—much like on the Auto head unit—with all of the same options we saw above.

If you flip your phone into landscape mode, however, the controls move to the right side. Also like on the Auto car experience, the menu is found in the top-left corner. The contents of this menu will change according to whatever is running in the foreground.

There are also options to turn Wi-Fi off when Auto is running to save batteryand to automatically launch Auto when a certain Bluetooth connection is detected. This can be super useful if you have a Bluetooth head unit in your car—once the phone is connected, Auto will take over. Very cool. Of course, there are downsides to just using your phone. When it comes to multitasking and efficiency, Auto head units are superior to just using a phone in the car in almost every way.

While on vacation, I used my head unit for navigation, music, texts, and phone calls—essentially everything it can do—constantly, and it never missed a beat. The music would automatically pause when a call or text came through, then start right back up afterwards.When buying a sound system for your vehicle, there are many aspects to take into account. The question of whether some are better than others is usual. And here we will answer that and other issues. Surely you have heard name the radios of 1 and 2 DIN.

They may tell you that you need one or the other because it is what your car currently has and replacing it will be much easier if you choose one of the same sizes. It is straightforward to decide which one you need. If your car has a single DIN unit that means that the front is about x 50 millimeters, on the other hand, if you have one of two, it will be the same width but twice as tall, that is x millimeters.

These are standard measures. On the other hand, if the vehicle comes with one of a DIN, it will be almost impossible to change it for a double, for space. DIN standard specifies the dimensions for the central unit of the car when viewed from the front; it must be the size we mentioned before x 50 mm.

They are still called DIN radios because it was this German institute that invented the original standard. You will think that only two measures have been taken, not to mention the depth.

Nor do they suggest depth ranges for the central units of cars. That means that some equipment will not look good on certain vehicles. Some modern central units are the right size for contemporary cars.

But there are always exceptions. That is why it is a good idea to check the dimensions of the radio and the specifications of the vehicle before making the purchase — either one or two DIN. We already mentioned the size of a single DIN of x 50 mm. There is also the option of 1. These units are 75 millimeters tall.AF- alternate frequencies which helps change to a different frequency when the station you are listening too is getting out of range. PTY- programme type which will automatically tune into a station broadcasting Pop, Classical, News or whatever else it has available.

AST- autostore which benefits the long distance driver by scanning the waveband in the area of travel and automatically storing five or six strongest stations in order of signal strength.

A combination of high and low pass filters connected in series with an overlap between the lower and upper freqencies, usually used for the mid-range in a 3-way component system.

The Bass Boost button. It's supposed to be used when you're listening to music at lower volume levels. Remember from above that at low volume levels we don't hear the low end and high end as well. When you engage the Bass Boost button on a system it gives a little EQ boost to the low and high end of the material it's processing.

Bluetooth is a wireless technology standard for exchanging data over short distances. This data can be text, photographic or audio. Bluetooth is used mainly in car audio for making and receiving telephone calls.

Capacitive touchscreens are highly accurate and respond instantly when lightly touched by a human finger As opposed to the resistive touchscreen, which relies on the mechanical pressure made by the finger or stylus, the capacitive touchscreen makes use of the fact that the human body is naturally conductive.

Capactive touchscreens tend to be more expensive than the Resistive counterparts. CarPlay is a smarter, safer way to use your iPhone in the car.

I'm interested in getting CD player and radio for my car, but I'd also like to have the option to sign up for satellite radio.

Please offer some advice if you understand what I'm getting at. Many thanks! The receiver is capable of controlling the tuner so is "satellite radio ready" because the control features are there but it lacks the tuner which you need to buy seperately. It has to say satellite ready installed or integrated not just ready then that means the satellite ready is ready to go with no seperate tuner purchase require.

I was confuse for awhile until I've seen enough reciever ads and models and displays that I figure out the lingo and the marketing scam to confuse people to thinking that their receiver has satellite ready already installed but that is not the case. Do car stereos which say "satellite radio ready" have the satellite radio built into it already?

Please offer some advice The universal tuner, e. The tuner is installed out of sight. The required Sirius antenna connects to the tuner. When complete, the "Sirius Ready" radio now functions as if it was an original factory installed Sirius radio. With the new tuner, you'll need a Sirius antenna and a cable to connect the new tuner and the vehicle's factory installed radio. Unlike a separate Sirius radio, there is no separate radio mounted on the dash to a vent or suction mount, no wires exposed.

Bottom line, a Sirius Ready radio needs a Sirius universal tuner - not a separate Sirius radio. With a tuner installed, all of the Sirius Ready will look and act like a factory installed Sirius radio.

My car came sirius ready but i came to find out that i have to by the antenna and converting system from mazda before any subscription would work. I would assume that it just means the hook up is available if you decide to install the receiver later you can plug it straight into the system. However since its an after market system it may have everything in one package ready for you to call down the satellites upon your car.

I think it is ready for you to install a Satellite Radio Reciever, which then you can hook up to your stereo system.
