How to Connect a 2 Channel Amplifier to DVC Subwoofers

Dual voice coil subwoofers offer a good amount of flexibility considering the multiple configuration options available. Two- channel amplifiers are optimized when running DVC subwoofers in 2 ohm stereo. This configuration maintains stereo bass, while running the amplifier in an ideal 2 ohm load. The connection layout for this configuration looks like a conventional stereo connection, with the terminal leads on the dual voice coil subs connected.

How to Calculate Power in a Parallel Circuit

When resistors are wired in a circuit with a constant voltage, you can calculate the power of the circuit if you know the value of the voltage, in volts, and the values of each resistor, in ohms. Once you have calculated the value of the total resistance of the circuit, you can use Ohm's Law to find the total current, in amperes. You then have all the information you need to calculate the power, which is given by the formula: Power = Current x Voltage....

Demagnetizer Instructions

A demagnetizer is a standalone electrical device that removes the magnetic field present in metal components prior to cleaning, plating or connecting the component with another part. Demagnetizers work by reversing the magnetic field away from the component. Demagnetizers should not be used on items that are to be used on magnetic conveyors, magnetic chucks, lifting magnets, magnetic separators, tools that are magnetized or holding fixtures, since the magnetic field is being removed...

How to Hook up Your Amp Wiring Kit

Wiring an amplifier correctly is as much a performance as safety issue. Proper fusing and wire routing is important in preventing shorts, fires and damage to equipment. When in doubt, keep in mind that the most successful wiring jobs are ones that have no exposed wiring in the cabin, and where the amplifiers are kept reasonably cool. Correctly installing an amplifier's wiring will go far in maintaining long equipment life and good sound....

How to Bridge a 10-Inch DB Drive Subwoofer

Wiring a DB Drive subwoofer is a fairly straightforward process as far as subwoofer installations go. With all models of dual voice coil, the best method if bridging an amplifier is to utilize a dual voice coil woofer in 4-ohm configuration. This versatile woofer and amp combination will not only provide solid output, but offer a stable load for the vast majority of quality amplifiers....

How to Bridge Four 12 Inch Subwoofers

Utilizing four subwoofers in a bridged configuration has the potential to create a thundering installation. Most quality bridgeable amplifiers have the ability, if wired correctly, to successfully drive four 4-ohm woofers, driven in series. This creates a 2-ohm load at the amplifier, safe for most amps. Running four subwoofers acoustically doubles the output of two, allowing for powerful bass with smooth response if installed correctly....

How to Wire a Power Cap

A power capacitor or cap as it's called, is installed between the power source and the appliance it feeds. The capacitor stores electric power for the appliance to use without drawing energy from the power source. This allows use of an appliance such as a car radio without draining the battery. Most auto alarms use capacitors that supply a charge for a limited time. The capacitor is drained once the alarm stops but the battery still holds a charge. Capacitors with proper wiring can protect batteries and serve appliances while the electric system is turned off....

DIY LED Dome Light

Dome lights are typically located in the center of your vehicle's headliner. They illuminate your interior when a door is opened by a switch on the dashboard or on the light housing itself. Installing an LED (light emitting diode) dome light is easy, and it will use less energy, last longer than incandescent dome light bulbs, and will often be much brighter than stock. Direct replacement LED dome light bulbs are sold through several retailers on-line, and at your local auto parts store....

How to Install a Speaker in a 95 Jeep Wrangler

The 1995 Jeep Wrangler is a durable and versatile vehicle for getting you where you want to go in tough conditions. But the factory-installed sound system doesn't always get the same high marks as the rest of the vehicle. One quick and relatively easy way to improve the sound of the Jeep's stereo is to change the front speakers, installing new aftermarket models in place of the existing factory models...

How to Wire Up a 4-Ohm DVC Subwoofer

Dual voice coils subwoofers are a popular type of subwoofer for car audio applications. These subwoofers have two sets of terminals, each connected to a different voice coil. By using different wiring configurations, the subwoofer can present a different impedance to the amplifier it's connected to, allowing many different types of amplifiers to be used. There are two wiring schemes used with DVC subwoofers--parallel and series wiring....

How to Buy Car Stereos in Bulk

Buying car stereos in bulk may seem like a smart idea, especially for those in the business of reselling, but finding the best price can prove difficult. Purchasing multiple stereos at retail value can cost a small fortune depending on the brand. Knowing how to find the best deals on car stereos sold through wholesale can help you save money and find good-quality stereo systems...

How to Wire a Car Audio System as 2 Ohm

The concept of resistance, as measured in ohms, causes much confusion for many car audio novices. Resistance is the result of what the car audio system is directing its output towards; in this case, the car's speakers. If you want to wire a car audio system as 2 ohms, you'll need to employ speakers, or a combination of speakers, that present a 2-ohm load to the receiver or amplifiers in your car audio system. Since most car audio speakers are 4 ohms, you'll need to employ parallel wiring to achieve a 2-ohm impedance....
