    Video "How to..." and informational car audio guides

    Here are some 'how to' videos for several important car audio related things. They are mostly from the guys at http://edesignaudio.com
    I'm sure they would be really useful for some.

    The gain settings one is an excellent base line for people who dont know the more advanced techniques.
    Bass Boost Sucks is a good one too. A lot of people do not realize exactly what it does to the signal.


    Setting Your Gains :
    (Note: this method will work every time as long as the math is done right and the manufacturer isnt lying about the amp's spec. If your amp is underrated, like most old school amps and many of the best modern unregulated amps, you will not get the amps full potential. The only way to safely get the most out of your amp is to use an oscilloscope.)

    How to Build a Speaker Box:
    (Note: This is the most common method. You can use other saws and there are methods to use NO screws or nails to assemble the box. Elemental uses a CNC machine to cut their wood and EFS rather than MDF now. Furniture grade Burch Plywood is a more expensive and heavier alternative to MDF but some prefer it.)

    How to Properly Ground Your Amp :
    (Note: This video does not mention the importance of knowing what your screwing into. It also does not mention how you need to know what is on the other side. Make sure your not screwing into a wire, brake line, or GAS TANK! You can also run ground wire directly from the amp to the negative battery terminal.)

    I will be adding more to this thread from Elemental Designs and other sources.

    Non video guides:

    How to do the Big 3 from the Steve Meade Designs forum.
    On our cars, with the stock alt, it is not needed to do 0 gauge like their guide recommends. 4 gauge will more than handle the 85-96 amps of your stock alt (alt varies depending on options and year)

    Additional notes for the 'how to ground your amp' tutorial...

    Dont under estimate the importance of a good ground. A poor ground can cause anything from noise in the system to component failure.
    Make sure your ground wire is the same gauge as your power wire.
    The reason for grinding away the paint is to insure a straight metal to metal contact for the best possible electron flow. You can paint over it all once the connection is secure to prevent rust. I personally typically use a zinc spray. Its a conductive spray that helps prevent corrosion.
    If your building an SPL system or just running a ton of power it will probably be best to simply run a ground wire from the amp back to the battery's negative terminal. Many competitors will recommend this method. Also, if your battery is already relocated to the trunk you might as well wire directly anyway.
    If your car/truck has a frame rather than a unibody you could drill a hole through your trunk/cabin and connect the ground directly to the frame.
