THE 7 BEST FACTORY CAR SOUND SYSTEMS

Jaguar XF: Bowers & Wilkins
Bless the Jaguar XF: it showed up just in time to clinch the sale from Ford to Tata. As great as the car is, we're inclined to love on its upgrade audio system even more. For a mere $1800 or so, the 440-watt Bowers & Wilkins system offers up a bounty of Dolby 7.1 surround, 14 speakers, and the cleanest sound this side of a Magic Eraser on Michael Chiklis' scalp. There's perfect MP3 integration, a touchscreen for audio settings, incredible punch even from compressed music files--everything a discriminating music lover looks for other than a place to burn their "really? seriously?" Norah Jones CD, bought in a low-blood-sugar Starbucks moment.

Lexus LS 600h, among others: Mark Levinson
The entire Lexus range gets Mark Levinson love, but it's the glassy-smooth sounds emanating from 19 speakers in the big LS 600h sedan that will lull you into loving even Miley Cyrus. And what better place to hear it all, than the rear seats of the LS, cruising smugly in traffic while Driver points out your hybrid street cred through clever hand gestures?

BMW 7-Series: harman/kardon Logic 7
The newest 7-Series has some marvelous room to spread out--and few cars indulge audiophilia so purely. BMW matches the 7-Series' lounge-like atmosphere with the Logic 7 surround sound system and a state of the art list of ways to pipe in the music of your choice. There's a hard drive for music storage, an iPod connectivity interface, a six-disc DVD changer, and premium sound with Sirius Satellite Radio and HD Radio. BMW also fits the 7er with a rear-seat entertainment system, so the kids or passengers can get in on the top-notch sound.

Infiniti G37 Coupe and Convertible
Infiniti's premium-sound package for cars like the scrumptious G37 lineup not only has the aural goods--it has one of the best user interfaces for iPods, iPhones and other inferior MP3 players (Zune, it's you, babe) as well as radio and satellite-radio bands. Teamed up with an optional 11-speaker Bose Studio on Wheels premium audio system and a Music Box 9.3-gigabyte hard drive, it's difficult to top--unless you go topless with the G37 Convertible, which programs in a top-down stereo mode that shifts audio signals to the driver's seat

Hyundai Genesis
It's the same system as in the Rolls-Royce Phantom--the same brand, at least. The paradigm-shifting Genesis sports an available Lexicon surround-sound audio system with 500 watts, 12 channels, and 17 speakers, plus an HD radio tuner. There's also an iDrive-ish controller to manipulate it all, and it works surprisingly well, so keep your smart mouth to yourself. All Genesis sound systems come with XM Satellite Radio and inputs for USB and iPod attachments, too. Lacking? That big Rolls-style radiator grille. We'll let you be the judge, positive or negative on that.

2010 Ford Mustang
Ford's Shaker 1000-watt system is just that--the best, easiest way to make the Mustang's natural good vibrations go to eleven. The Shaker setup is available across the V-8 lineup, from GT to Shelby GT500--and its 1000 watts of power plug-and-play nicely with Ford's Bluetooth-enabled SYNC controller and available Sirius satellite radio. (A "Shaker 500" will have to do for V-6 'Stangs.) Bring your own Beach Boys MP3s--or AAC files, if you're one of those hardcore Apple-blinded loyalists.

Chevrolet Malibu, and most of the GM lineup
It's not luxuriant sound that makes the Malibu's stereo--and most GM stereos--good enough to make this list. It's their utterly logical preset setup. You can use a single set of preset keys to program in stations on AM, FM and XM. For those of us who still use all three bands, it's a godsend. Steering-wheel audio controls and USB links for MP3 players are good, too--they scroll through all presets and seek as well--but GM's USB port integration has taken some hits for its, uh, knockoff look. Like seek buttons on the steering wheel, this whole preset thing has us asking: do automakers do any benchmarking anymore, and why isn't this the new normal?

What are the cars with the best audio and more cheap

The follows 10 cars thay have a great sound.

10.-Scion tC

If you love the sweet Pioneer sound system that's standard on the xB but can't quite embrace that car's bread-box aesthetic, perhaps a tC would be more to your liking. This Scion delivers all the sonic excitement that the marque is known for, with a six-speaker stereo that offers CD and MP3 playback, and iPod integration. It also comes to the table with an exterior that considerably more low-key than that of your typical Scion.

9.-Volkswagen Jetta

The Jetta starts at a frugal $16,990. For a true aural treat, though, you'll need to step past the base S model and invest in the SE, SEL or limited-edition Wolfsburg trims; these models start at $20,875. With these trims, you get an ear-pleasing standard 10-speaker sound system with a six-CD changer and auxiliary input. You also get Sirius Satellite Radio.

8.-Mazda Mazda3

There's nothing really fancy about the Mazda3's audio system; it just offers superb sound quality. Base models start at $13,895. All trims offer an optional six-disc CD changer for $500, and Sirius Satellite Radio is also offered for $430. Step up to the Grand Touring version and you can have the option of a 222-watt Bose audio system with a subwoofer. It's bundled with a six-disc CD changer and a moonroof. At $1,335, it raises the price of the car considerably but if great sound quality is what you're after this is the way to go. When all is said and done, the Mazda3 Grand Touring with the Bose audio system will run you just over $20,000.

7.-Jeep Compass

Optional (at a cost of $795) on the Jeep Compass base Sport trim is a premium Boston Acoustics sound system. This setup boasts two articulating liftgate speakers; like those offered on the Caliber, they flip outward for those moments when you're in need of open-air entertainment. You'll also find six Boston Acoustics speakers with subwoofer, a leather-wrapped steering wheel, Sirius Satellite Radio with a 1-year subscription provided by Sirius, and steering-wheel-mounted audio controls. A stripped-down version of this package — featuring just the two articulating liftgate speakers and six Boston Acoustics speakers with subwoofer — is offered for $495 on the more luxuriously outfitted Limited trim. The base-model Compass goes for $16,475.

6.-Dodge Caliber
Skip the base Caliber SE if you want the sweetest ear candy. The Caliber SXT starts at $16,620, and offers an optional stereo upgrade for an additional $495. For this extra coin, you get six Boston Acoustics speakers with subwoofer and a Musicgate Power sound system. You also get two articulating rear liftgate speakers. This unique feature allows you to adjust the speakers so they face outward from the liftgate, thus making it easy to throw a tailgate party should you feel so inclined. The Caliber R/T starts at $18,395, and offers this upgraded sound system as standard equipment.

5.-Mini Cooper
For the base Cooper's $18,050 price tag you'll get a six-speaker stereo with an auxiliary jack and a single-CD player. The good stuff, however, is on the Mini's options sheet. For $500 you can opt for the Mini Hi-Fi audio system which adds four speakers for a total of 10. To get the most of the upgrade, consider checking the "HD radio" box, which gives the car the capability of receiving AM and FM stations via a digital signal for improved audio quality. It adds another $500 to the total tally, but the sound-quality upgrade will no doubt be worth it to those who want the best but can't always afford to pay top dollar.

4.-Scion xB

If you love getting a lot for less, you'll flip your lid for the xB. This savvy Scion comes at a base price of $15,750, and offers standard features designed with audiophiles in mind. Included is an impressive six-speaker Pioneer stereo with a CD/MP3 player. The system offers both an auxiliary MP3 jack and a dedicated iPod jack that enables the user to guide iPod playback via the head unit controls.

3.-Nissan Versa

The Nissan Versa starts at a dirt-cheap $12,710. Clamber up to top-of-the-line SL CVT-equipped models, though, and you get to enjoy a killer $300 audio package; these models go for $15,810. This package includes a premium speaker upgrade that allows buyers to savor the intoxicating thump of a 100-watt Rockford Fosgate subwoofer. A useful iPod interface system is also offered, for an additional $290.

2.-Honda Civic

The MSRP for base DX Honda Civic models is $14,810 for coupes and $15,010 for sedans. For a truly superior sound system, though, you'll want to invest in the upgraded stereo that comes with EX models. This inflates the price by another four or so thousand dollars, but it's money well spent. EX models offer a 350-watt system with seven speakers including a subwoofer, RDS, an auxiliary jack and speed-sensitive volume control; sound quality is very good for a car in this price range. Add the navigation system for another $950 and you get a memory card slot and an XM radio-ready head unit.

1.-Ford Focus

The Focus is distinguished by its innovative Microsoft-developed Sync system. This unique setup works as a Bluetooth connection for your phone; it also functions as a voice command interface for digital music players. With Sync, saving voice tags or building lists of phone numbers isn't necessary since the system is able to wirelessly access your device's phonebook. Sync is offered as a $395 option, but keep in mind that it's not offered on base editions, and is only available on SE and SES models. Pricing on these models starts at $15,225.

Sound recording and reproduction is the electrical or mechanical inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording.

The first practical sound recording and reproduction device was the mechanical phonograph cylinder, invented by Thomas Edison in 1877 and patented in 1878. The invention soon spread across the globe and over the next two decades the commercial recording, distribution and sale of sound recordings became a growing new international industry, with the most popular titles selling millions of units by the early 1900s.

Acoustic analog recording is achieved by a small micriphone diaphragm that can detect changes in atmospheric pressure (acoustic sound waves) and record them as graphic sound waves on a medium such as a phonograph.

Digital recording and reproduction uses the same analog technologies, with the added digitization of the sonographic data and signal, allowing it to be stored and transmitted on a wider variety of media. The digital binary numeric data is a representation of the periodic vector points in the raw analog data at a sample rate most often too frequent for the human ear to distinguish differences in quality.
