Car Audio Capacitors: Why You Can't Do Without Them
By Mantius Cazaubon

I've heard the question asked many times before, 'Do I really need a capacitor?' Before answering that question I ask, 'Do you have a high powered system?' 'Does it require sudden power bursts?' 'Is your amplifier being robbed of power?' If the answers to my questions are yes, make every effort to connect a capacitor to your car audio system.

A capacitor is a bit similar to your car battery; it stores electrical energy. But unlike a battery it doesn't produce its own power, it simply stores it. A car audio capacitor will help you get the most from your amplifier. It will store power for release on demand, delivering it to your amplifier just when it's needed.

Car Audio Amplifiers - More Good to Know Info
By George Steiner

The car audio amplifier... its soul purpose is to take a low level signal from the source unit and transform it into a high level signal for activating the loudspeakers.

Amplifiers range in power from about twenty watts per channel to over one thousand watts per channel. Would you believe that the prices range anywhere from fifty dollars to several thousand dollars depending on features, power output and quality! Amplifiers range from one channel of output to as many as eight channels. The most common amplifiers are currently two and four channel models.

Amplifier Power Ratings Power amplifiers also have "optional equipment". These features include built-in active crossovers, equalizers, signal processing and speaker level inputs. When shopping for an amplifier consider that all power ratings are not created equal.

Car Audio Systems - Bigger is Better?
By George Steiner

Are Big Car Speakers Better?

If you are planning to purchase car speakers, there are things you need to know in order to make the best choice. A clear mind and a basic plan of what you intend to buy are crucial when shopping for car speakers. Big car speakers do not always mean better speakers.

Purchasing speakers for your car can end up being more costly than necessary if you buy speakers that have numerous features you won't use. Keep in mind that top quality audio speakers cost more than some other brands, but are generally worth the investment. If big car speakers are your preference, make sure you buy a dependable brand name and make certain the speakers will provide you with crystal clear sound.

Car Audio Crossovers: Why You Can't Do Without Them
By Mantius Cazaubon

I've heard the question asked many times before, 'Do I really need a crossover?' Without wasting any time I quickly answer, 'Yes you do'. Whether it's a passive crossover or an active crossover, your car audio system will never sound good without a crossover. I want to make myself very clear here, so before you get confused let's talk about what a car audio crossover is and why you need one.

A crossover is a filtering device which limits the frequencies that reach a speaker. It splits a music signal into separate frequency ranges and sends them to speakers that are designed to best reproduce each frequency range. For instance, only high frequencies would be sent to your tweeters, midrange to your mid range speakers, and lows to your subwoofer.

Planning a Car Audio System Installation
By Will Reece

With such a wide range of components and gadget on the market for car audio systems, the big question is "Where do I start?"

First you must decide what exactly you wish to do. If you are wanting to build a car audio system for a daily driver (the car you drive back and forth to work) with good sounds, but you are not interested in competing, a system can easily be put together for under $1000. However, if you are looking for the all-out bass monster, be prepared to drop in some big bucks into your system.

One of the most important things to keep in mind when building a car audio system is planning. Get an idea of where you are going to place components, subwoofers, amplifiers, and power distribution. A lot of headache can be avoided with the proper planning!!
