Guides & Articles

  • In this article, we'll focus on subwoofers and the enclosures (or "boxes") they may be housed in. But first, we'll clarify the differences between a subwoofer and a woofer. Both these terms are often mixed up, creating confusion about functions these components serve.
  • If your current car stereo doesn't produce sound that's as clean, crisp, and listenable as what comes out of a high quality set of headphones, chances are it's because one or more of your speakers are past their prime, compromised, or even blown. If you're not the original owner of your vehicle, you have no idea how much or how little any previous owners abused the stereo system. Most OEM (Original Equipment Manufacturer) speakers in vehicles naturally lose quality over time no matter how they're treated, and if you spend 30 minutes or more in your car each day, you'll appreciate the benefits that higher quality aftermarket speakers offer over OEM ones.
  • Invented in 1994 by the Swedish company Ericson, "Bluetooth" technology uses radio waves to send information wirelessly between one or more devices located in very close physical proximity. While AM/FM radio signals, satellite transmissions, television, and cell phones also use radio waves, Bluetooth uses the unlicensed but regulated 2.4 - to 2.485 Gigahertz band range.
  • Thanks to advancements in electronic technology over the last several decades, aftermarket car alarm systems have become much more sophisticated - without becoming significantly more expensive. While it's true many modern cars already feature an OEM (original equipment manufacturer) immobilizer system which shuts down the engine control computer and starter unless computer chip keys are inserted in the ignition, there are still a number of reasons why aftermarket security systems are beneficial. For example, the typical new vehicle won't recognize if a window has been shattered or thieves are lifting it off the ground to steal the wheels. And they won't help you track your vehicle's location and use in the event of theft or carjacking.
  • According to the U.S. National Safety Council, 30% of reported accidents occur when one or more vehicles involved are backing up. This totals to over 300,000 incidents a year and costs approximately $1.3 billion in damages. The news gets worse when personal injury is factored in, and young children fare the worst. On an average week in the U.S., 48 children are injured and 2 die as a result of vehicles backing up. In 82% of those cases, the children involved were under 4 years old, and most of that 82% consists of children under the age of 1.
  • When you're sitting on the shoulder of a highway with flashing lights behind you and a police officer at your window, there isn't much you can say about the fact that you were driving too fast. There's no doubt that said officer already has your excessive speed documented with a radar or laser gun, or they would not have bothered to chase you down in the first place. In this article, we'll examine how radar detectors and laser detectors work so that you can make an informed purchase and protect yourself from costly speeding tickets that raise your insurance rates.
  • Cell phone companies along with fans of the latest high-tech devices have routinely declared for years that dash-mounted GPS (Global Positioning System) navigation systems and screens are obsolete and will soon be gone completely. They claim that there is no reason to buy one because smartphones using Apple maps or Google maps outperform them in every way.
  • When you're looking to stream music from an iPhone, iPod, Android smart phone, MP3 player, portable CD player, or other device to your car radio so you can hear it over the speakers, you need the proper connections. There are a wealth of kits on the market with cables, modules, and even transmitters to help you do just that. However, the choices can be confusing and overwhelming in many cases. In this article, we'll take a look at the types of portable device-to-car-radio connection kits offered to help you make an informed decision for yourself or someone you care about.
  • In this article, we'll discuss the basics of your vehicle's audio system wiring. Specifically, we'll look at the addition of one or two amplifiers to your system, and examine the steps involved for both the mechanical and electrical installation. Refer back to these two illustrations while reviewing the text.
  • The purchase of a new stereo (also called "receiver" or "head unit") brings the promise of better sound, the thrill of new features, and the enjoyment of simply experiencing music in a way that is not possible with a factory sound system. We hear the excitement and anticipation in our customers' voices every day as they select and order their new equipment, and we help guide them through the process of stereo installation all the time. We know our customers' questions, and we see the most common roadblocks they come across.
  • The digital multimeter (DMM) is an extremely versatile tool for troubleshooting electrical systems and diagnosing engine performance – combining the functions of many electrical measuring devices into one. Digital multimeters can measure voltage, electrical resistance, continuity, current, or test diodes in either direct current (DC) or alternating current (AC) with just a turn of a knob. They have the capability to make precise measurements out to 2, 3, 4, or more decimal places. In automotive applications, they can test the degree to which wires, switches, fuses, relays, and motors are conducting electricity properly. Top-of-the-line DMM's are also able to read engine rpms and dwell as well as electrical duty cycle, frequency, pulse width, diode condition, and in some cases, temperature.
  • By definition, an automotive battery is an electrochemical device that stores and provides electrical energy on demand. Electrical energy is produced inside the battery by a chemical reaction occurring between two dissimilar plates immersed in an electrolyte solution. When the battery is discharging, it changes chemical energy into electrical energy and releases current. During charging, electrical energy is converted back into chemical energy and stored.
  • Hybrids are everywhere these days and can be defined as, "any vehicle combining two or more sources of power which can directly or indirectly provide propulsion." Although all hybrid vehicles on the market today use batteries as one of the power sources, there are different mechanical layouts and operational approaches in the way electric motors function alongside gasoline combustion engines. Those that use a combustion engine to generate electrical power are described simply as "hybrids", while vehicles with larger battery packs that can also be recharged with an electrical cord are known as "plug-in hybrids". Vehicles with electric motors and without combustion engines are not considered hybrids, because they are "pure electric" vehicles. These so-called "EVs" are outside the scope of what we are covering here.
