Subwoofer Sizes

Subwoofers have been used widely in cars to enhance the sound quality and make the driving experience more enjoyable. There are 4 main sizes of car subwoofers:
8 inch subwoofers: They are considered to be the smallest subwoofers for pumping out bass without sacrificing trunk space.
10 inch subwoofers: They are commonly used subwoofers for installations where space is at a premium.
12 inch Subwoofers: They are the most common subwoofer size; 12" subs provide good response at low frequencies.
15 Subwoofers: They are larger car subwoofers that hit harder and even deeper than 12 inch subwoofers.

Before you buy your next subwoofer, it’s really important to check out which subwoofers fits your needs the most. This way, you will eliminate any future problems when it comes to installing you sub.

Amp Wiring Kits Sizes

Be sure to select the wiring kit that's appropriate for your amplifier. Kits come in a variety of sizes: 10-gauge, 8-gauge, 4-gauge:

- 2 Gauge amp wiring kits: Mainly used for high powered systems and you need to buy a capacitor as well.

- 4 Gauge amp wiring kits: Generally for systems 400 to 1000 watts.

- 8 Gauge amp wiring kits: Is used for systems 100-200 watts.

The most common and familiar piece of Car audio equipment is the radio/tape player/CD player/DVD Player which is generically called as a Head unit, which also can be called a head deck, after older tape decks. It is also the most likely component to be upgraded with an aftermarket item. A recent development in head unit technology has been the addition of CD players with MP3, Ogg, WMA, AAC, and USB, Bluetooth and Wi-Fi support. Even with the rampant ubiquity of solid state MP3 players, car audio systems with line-in jacks and other standards are only in their infancy, and that since tape adaptors are often used with tape players, people are now viewing car radios with built-in CD players as "misfeatures" of the audio system since people now often "rip" their CDs onto their computers.Most modern cars include at least a CD player/ CD recorder, and some have the option for a CD changer, which holds multiple disks either in the head unit itself or in a separate unit usually located in a trunk or console.More recent is the addition of DVD players and LCD screens. Depending on the head unit, the LCD screen is either integrated such that it slides out and folds up, or integrated into the instrument console. Otherwise, the DVD head unit feeds video output into separately mounted displays, either folding down from the roof, or mounted into the headrest for viewing by rear seat passengers.

The video screen may also show video output of an integrated component such as a navigation system 3G cell phone or parking cameras that could be automatically activated when the car is put into reverse.


Advances in electronics allowed additions to the basic radio and Motorola offered 45 rpm disc players fitted to some Chryslers from as early as 1956. Tape players using reel to reel equipment followed but their bulk ensured popularity was limited but this changed in 1964 when Philips launched the Compact Cassette. Other early manufacturers and car enthusiasts started building extra car audio amplifiers to run on 12 volts (the standard voltage in automotive electrical systems). Jim Fosgate, later to become the founder of Rockford Fosgate subwoofers, was one such pioneer. The company a/d/s also brought an amplifier to market in 1978.At first, speakers from the home audio and professional markets were simply installed into vehicles. However, they were not well suited to the extremes of temperature and vibration which are a normal part of the environment of an automobile. Modified drivers were developed to cope with these factors.Today, advances in acoustic technology mean that even two 10-inch car speakers in a well-designed efficient enclosure can produce more than 100 decibels SPL (sound pressure level) within the cabin.

Car audio competitions started in the early 1980s in a quest to find the loudest and/or most outrageous installations. For example, in 1985, Wayne Harris famously modified a 1960 Cadillac Hearse to feature three 24-inch subwoofers as well as eight 12 inch car subwoofers. Little consideration was given to sound quality early on, but in the early 1990s, several organizations, including IASCA, began car audio competitions focusing on sound quality. The two styles -- SPL vs. sound quality -- have become almost mutually exclusive. The loudness competitions have become known as dB drag racing.

Cool Cars

What is at the heart of cool cars everywhere? Is it the speed they can travel at? Is it the thought of the wind brushing your hair? If it's the latter, then you have a soft top (convertible), or someone's pinched your roof!

Well, it could be either of these things. Or perhaps cool cars mean something else to you entirely. But to me, it is the shape of the car. Not so much cool cars but cool curves ... Sexist? Perhaps, but true none the less. I think I classic car is defined by it's architecture.

Look at any sports models over the years. What has defined them, made them stand out? Ok, the price is one thing, but take a step back and really think about what makes a hot car so cool?

There is something else that makes a car cool, at least as far as I am concerned. And that is the interior. Or to be more precise, what the interior is made of. My first car lives in my memory to this day, and surely that is the mark of a cool car. I can remember the smell of the leather seats and look of the wooden dash surround. Plastic just doesn't cut it, especially not in more mass produced models.

And it had curves!

So what else puts the cool into a car for you?

For me personally, low is cool. The closer I am to the ground, the better I feel. Some people like to have a high vantage point, and perhaps that is cool to them. It certainly helps to have a better view of the road from a practical point of view.

For many, the colour of a car defines its 'cool'. Red is often the colour to fuel associated with the hottest cars around (not surprisingly really). But what about black? There is something mystical about jet black automobiles, don't you think? To some, an unusual colour is the height of chic as far as a car is concerned. You might not like bright yellow or lime green, but your will always notice them, won't you. And to some folk, that is all that is required from a cool car.
