Now let's take a car audio system as an example to show you exactly how to install a capacitor to an Amp. . Notice that you should always discharge the capacitor before further operations. Besides, get help from a professional mechanic if you're not sure about what's going on. How to Install a Capacitor to an Amplifier (Amp)?Turn off the amplifier and disconnect it from the power source.Identify the positive and negative terminals on the capacitor.Connect the positive terminal of the capacitor to the positive terminal of the amplifier.Connect the negative terminal of the capacitor to the ground (chassis) of the amplifier.更多项目 [pdf]
Connect the power wire from the amplifier to the capacitor’s positive terminal. Use a crimping tool or soldering iron to securely connect the wires. Connect the ground wire from the amplifier to a suitable grounding point, such as the chassis or a designated grounding point.
Connect the capacitor’s positive terminal. Whether you are connecting to the battery, amp, or a distribution block of some kind, you need to connect the positive terminal of the capacitor to the positive terminal of the other component by running a wire between them. Eight gauge wire is usually recommended.
Connect the capacitor in series with the speaker to create a high-pass filter. Connect one terminal of the capacitor to the speaker’s positive terminal and the other terminal to the positive terminal of the amplifier. Connect the capacitor in parallel with the power supply terminals of the amplifier.
To wire multiple capacitors, you can either wire both ground wires together by running one ground wire to each of the cap’s negative terminals. You may also ground each capacitor separately. Run the power wire through the amplifier’s positive terminal and to the battery’s positive terminal.
Before you install a capacitor, you must charge it to prevent blowing fuses. Use a voltmeter along with a resistor to charge your audio capacitor. Once the voltmeter shows 12 volts, the power capacitor is charged. Now you can wire the capacitor in parallel with your car amplifier.
A car audio capacitor has two terminals, positive and negative. Connect the positive terminal to both the amplifier’s and car battery’s positive terminal, and the negative terminal to the ground. Make sure you secure the ground wire to the vehicle’s metal chassis. Where you mount the capacitor depends on your car.

Capacitors are incredibly simple. a pair of conductive bits, separated by some dielectric media, and you just charge up that field between them until it eventually arcs if the voltage is too high. I started looking more into what material options for dielectric exist, and how changes in dielectric strength and constant. . Unfortunately while reading about capacitor dielectrics I came across a comment saying that even a small air gap between two dielectric. . The calculation that killed this path of DIY capacitors for magloops was that of power dissipation inside the dielectric material. I had seen tables of “tangent loss coefficient”, but thought that *those numbers seem small. .. . With dielectric losses understood, my choices returned to an air variable capacitor, or a vacuum variable cap. Seeing that most any size of vacuum variable cap started at $150+ on Ebay, I set out to make a simple. [pdf]
In this case, a vacuum variable capacitor is used, rated to a peak current of 57 amps and a peak voltage of 5 kilovolts. The magnetic loop design leads to antenna which is tuned to a very narrow frequency range, giving good selectivity. However, it also requires retuning quite often in order to stay on-band.
Magnetic Loop Calculator v.1.6 by KI6GD It’s a light magnetic loop antenna calculator that run on MS Windows, and allow to calculate capacitor values and voltage based on Loop circumference, conductor diameter, desired resonant frequency and the operating power.
TA2WK (old TA1LSX), 73 High Voltage Butterfly Capacitor for Loop Antennas - TA2WK (TA1LSX): Hello Everyone, Wanna build a magnetic loop antenna? Magnetic loop antenna is a compact efficient antenna that is ideal for portable operation or limited spaces and can be improvised inexpensively.
Similar to a separate coupling loop, it is optimally located opposite the gap in the loop, near the low impedance point of the loop. Traditionally, to allow a mag loop to tune below its natural self-resonant frequency, a tuning capacitor is shunted across the small gap.
The initial tests of the 40m loop were very promising. During a CW contest, the 40m loop made numerous DX contacts in Europe. When running at 500W, the capacitors showed no signs of heating (SWR drift, physical warmth, etc.). I ran several computer models of this antenna, to determine the effect of differing installation heights.
It’s a light magnetic loop antenna calculator that run on MS Windows, and allow to calculate capacitor values and voltage based on Loop circumference, conductor diameter, desired resonant frequency and the operating power. Works either in Standard and Metric units, and let you choose on material, and loop shape, as circular, square or octagon.
