guide to Power a Car Amplifier Using a Computer Power Supply

If you recently switched vehicles and have no room for that big subwoofer in your new car, don't give it or throw it away. Keep it. Use it inside or outside your house by having it powered by a computer power supply.












    1
    Find the power pin. In the power supply packaging (if bought new) there should be a pinout diagram. Look for the pin that says something along the lines of “Power on”, "PS OK" or other key words that indicates a on signal. It will be on the biggest pigtail.
        99% of the time it will be a green wire on new power supplies, but for older power supply “10+ years” the wire could be yellow or purple. If your power supply did not come with a pinout diagram, check the manufacturer website for a pinout diagram.


    2
    Cut the power wire from the pin and strip the end.

    3
    Cut the ground wire from the pin and strip the end. Refer to the pinout diagram to know which color is the ground wire. 99.9% of the time it will be the black wire.

    4
    Connect both striped ends using electrical tape or soldering iron or both.

    5
    Group all the 12v rails together by cutting them from their pins and stripping the ends. Refer to the Pinout diagram to know which color the 12v rails are. 99.9% of the time it will be the yellow wires.

Guide to Install a Tachometer

A tachometer is used to indicate the revolutions per minute (RPM) being performed by a car engine. Most cars with automatic transmissions are not equipped with a tachometer, since a tachometer is mostly used to indicate visually when it's time to shift gears. If your car doesn't have one, it's a good way to keep an eye on your engine speed. See Step 1 for more information. Getting Started     1     Get a tachometer and splicing connectors. You can either buy a tachometer new, which usually run somewhere between $30 and $50, or salvage on old one for relatively cheap and install it into your car.         The only other specialty item you'll need to complete the job is a package of quick-splice connectors, which are usually only a few dollars at the auto part store. The wires are about 16-18 gauge usually, so get connectors of the appropriate size.     2     Adjust the tachometer for the num...

Guide to Install a CB Radio in a Jeep Liberty

CB radios are recommended for a lot of off-road groups, as well as traditional uses. There are many ways to install this; the way presented here offers a cheap and effective way to do this if you are pressed for time and money, and use your CB radio infrequently.     1     Select a CB radio. For this exercise, the smallest Cobra was selected. It sells for about USD$35 at Walmart Online. You will also probably find it in local shops from $50-$60. There are other radios from Midland, Radioshack with similar dimensions. (Prices as at Sept 2007, feel free to update.)     2     Select a suitable location. A good location would be under the AC controls alongside of the cigarette lighter. When taking the plastic off you’ll see that you’d have to cut into the wall behind the plastic, it’s not deep enough to fit the radio. It’s possible but not quick, and the mic cord would be in the way of the transfer case shifter. Other ideas: ...
