Car Audio Wiring

A significant part of your entire car audio system consists of just wires. There are all kinds of cables and wires involved in installing a car audio system. You have power wires, speaker wires, amplifier cables, power capacitors, and what not. It is always better to be equipped with at least the basics before you go in for car audio installation.

The power wire is an important part of the amplifier installation. Select the proper gauge and fusing. A proper gauge prevents the amplifier from being choked off by the size limitations of the wire. Choose power wires with lots of strands, so that they are easier to install and don't break while passing through the numerous corners of the car. The jacket of the wire should be of a material, which can resist chemicals like oil and battery acids, which can wreak havoc on substandard wires.

You can go for wires with large number of strands for the car audio speaker wires. The jacket is not that important in this case, because the speaker is not placed in regions where it could encounter chemicals, as in the case of power wires. Oxygen free copper wiring is always recommended for car audio speaker wires. The size of the speaker wiring depends on the power going in to your speakers and the total length between the amplifier and the speakers.

Signal cables are otherwise known as RCA cables and assume importance for their noise rejection properties. Try and go in for a quality RCA cable, which would ensure trouble free performance in the long run. It is recommended that you go in for "twisted pair" cables. They are better at noise reduction. Needless to say, the quality of wires connecting car audio power capacitors and batteries should also be good.

One can find extensive information on car audio wiring by visiting online resources on the subject. Perhaps car audio professionals are best placed to offer you great advice on car audio wiring.

Radar Detectors: What Features Do You Need?

When you’ve decided to invest in a new radar detector, either for the daily commute or just day-to-day errands, buying a radar detector can seem a bit daunting. There’s a whole host of scientific breakthrough specs and technical industry jargon to weed through. Do you need a laser detector or a radar detector? What sort of bandwidth should you look for? Visual or audio alerts? Vg2 shielding mechanisms? Mounted or concealed? More than likely, you are just the average consumer, looking for an effective and reliable radar detecting unit to alert yourself to your own speed, as well as who and where you are being monitored for it. After having done a lot of research on the subject for my own interests, I have broken down all the tech specs and necessary features here, to save you the trouble of both unearthing unnecessary consumer headache, as well as buying the wrong radar detector for your individual travels.

· First off, there are basically three types of radar detectors as far as form is concerned: corded, cordless, and remote mount; each with its own set of pros vs. cons depending on your needs and lifestyle. The corded typically mounts to your windshield, and because of its location offers an aerial less-obstructed detection. Cordless is just that, and offers portable convenience. Lastly, the remote mount variety of radar detectors are mounted permanently to your vehicle, hidden from sight.

· What is the difference in laser vs. radar detection? Though radar detection has long been the chosen method of both drivers and traffic patrol, laser radar detection technology has been adopted by the latter. Police patrol will use laser radar for more accurate detection of closer-range vehicles, and standard radar detection for longer distance detection. Though it is more expensive to find a detection unit with both, it lessens your chance of being ill-prepared on the road. Moreover, you should only buy a laser radar model with 360 degree laser detection; otherwise you will only have the unit detecting in one direction, not from every angle of the vehicle, as is needed.

· City modes? They are basically, the blanket term for precise radar and laser detection in heavy radar frequency zones. The city mode will turn down the range of detection on your unit and perceive less interference or false alerts from external electrical mechanisms as well as other radar detectors in your immediate area. There’s much more of this technical buzz in the city…hence the term. So, if you live or drive in more metropolitan areas vs. rural ones, this would be a good choice for you.

· VG2, Spectre, and Invisible shielding technology. The VG2 alert is the basic technology that allows you to know when the police in your vehicle’s vicinity are using radar detector detectors or VG2 systems, to discern whether you are using a radar detector or not. Police officials adopted the Spectre system for detecting radar detectors on a broader and more precise playing field, and so the Spectre alert on your new radar detector will let you know when it is in fact being used. This allows you time to shut off your own radar detector, when alerted. The Invisible technology you may want to look for in a higher-end radar detector will be virtually undetectable to the above mentioned police-controlled devices, so you will never have to worry about shutting it down. All of these mechanisms are fairly new and will add expense to your radar detector, but again, it depends on how effective and reliable you need the radar detector to be.

· Bandwidths. Really, the only bandwidth you should have in your radar detector is the X bandwidth. Most frequencies operate on the X, and to incorporate any of the others (K, Ka, Ku), will just be asking for interference from unrelated mechanisms and external electrical stimuli. The result: less focus on what radar detection you should be picking up, such as police radar.

These are the basic necessary components in any reliable and accurate radar detector. You will find many more features available in these systems, but they are cosmetic in relation to the significant ones listed here. Start with these terms/tips for form and function, and then move on to whether you’d like luxury components such as voice alerts and enhanced LED displays.

About Car Audio Shows

A car audio show is one of the most thrilling things in car audio. They bring together people of different backgrounds who share a common love for car audio and competition.

There are four major car audio show competition organizations. If you think competing is right for you then these shows are among the best to attend. Not all car audio show organizations are available in all areas.

Car Audio Show Organizations

1. IASCA

it is the oldest car audio competition organization and also the largest. IASCA has traditionally been associated with sound quality competitions. Recently they have added the IDBL and SPL category as well.

2. USAC

USAC has become a major player in the “sound off” scene. USAC also has two competition formats on sound quality (basic and advanced categories) and sound pressure level.

3. DB Drag Racing

It was started and led by veteran competitor and sound off legend, Wayne Harris. DB Drag Racing is just what the name implies. The measurements that are displayed on a large drag racing type look like a tree and are very exciting to watch too.

4. MECA

MECA is the new thing. MECA classes its competitors by the extent of vehicle modification. They have Amateur, Stock, Modified, Custom and Master categories. They also offer SPL classes in each category.

5. SLAP

SLAP is an acronym for “Sound Looks And its Performance.” SLAP has three divisions. Among those, two are audio related. SLAP dB is the SPL competition and is classed by the total square inches of your woofers rather than power.

If you think you have what it takes to compete, check if you qualify. However, my advice is that you first take out time to witness whichever car audio competition you intend to participate in. Also take out time to read magazines that showcase different competition setups.

Should I Buy My Car Audio Product At Ebay?

Car audio at Ebay? Yes, you can get a good car audio system at Ebay. All you need to do is to log on to the net and sign-in at Ebay. This will not only save your fuel but also your time. So what is actually included at Ebay under car audio? Let’s take a peep in.

Sub-categories under car audio at Ebay

The various categories included at Ebay under car audio are...

• Car alarms and security

• Car amplifier

• Car audio in-dash units

• Car CD changers

• Car speaker and speaker systems

• Car subwoofers and enclosures

• Car video and navigation

• Installation products

• Parts and accessories

• Signal processors

• 12-volt portable appliances

There are, however, several issues you'd have to bear in mind if you intend to buy your car audio system or accessories at Ebay...

1) You run a huge risk. Ebay does not give you any guarantee on the product you're buying. All they provide is an interface for your transaction.

Therefore, if you're not experienced in using auction sites you'd be better off buying from an established car audio site.

2) You may be buying from a dissatisfied user who just wants to get rid of the stuff.

3) You cannot have any support if issues arise. You bought from another user, not an authorized outlet.

4) You're less likely to buy the latest and best. This shouldn't be a problem if you are more after making a bargain purchase than owning a reliable system that will serve you well.

If you do decide in spite of these and other setbacks, do yourself a favor: Research the seller and make sure you're not buying from a crook.

My best bet for your car audio system remains a car audio dealer who has expertise, not Ebay.
