We sell this cable by the foot. document.cir_mil_to_sq_mil_calc.square_mils.value = (document.cir_mil_to_sq_mil_calc.square_mils.value/10000); The most important consideration is the amount of current that will be carried by the wire. Most amplifiers have fuses on one end near the power connections. If we need to calculate the circular mils for a 10g wire, we simply square the diameter in mils.
The Following calculator will allow you to enter whole and fractional wire gauges (fractional wire gauges are used for magnet wire) between 0000 and 46 gauge. // Calculating current flow document.awg_to_sq_mm.radius_of_round_wire_inches.value = ((Math.sqrt(document.awg_to_sq_mm.circular_mils.value)/1000)/2); Resistance in Speaker Wire: The most common wire sizes used in car audio range between 4awg and 22awg. If it's less than or equal to 10g, subtract the wire g from 10g If it's greater than 10g, subtract 10g from the wire g // Calculating the circular mills For all of the calculators and tables on this page, unless otherwise noted, 'max power' is the RMS power output when the amplifier is on the threshold of clipping. document.volt_drop1.resistance_total.value = Math.round(document.volt_drop1.resistance_total.value); This means that the total cross sectional area is doubled when the diameter is increased by a factor of 1.414. Made from soft black PVC, each pant is 7 inches in total length. All of the voltage lost across all of the conductors are added together to give the total loss. If there was a warning of too few circular mils in the calculator above, the wire that you've chosen may have problems with overheating at full power. KnuKonceptz Bassik 8 Gauge Power Wire is simply that, a no frills, true American Wire Gauge spec cable. It also touches on field target competition. What is the difference between your Bassik and KCA Kable? When the item is back in stock we will send you and email letting you know that the product is now available for purchase. Various wire tables list slightly different values for circular mils and the diameter of the different wire sizes. For Those Who Refuse to Fuse: If you remember the formulas from Ohm's law, you will remember P=I^2*R. The power dissipated in wire will be in the form of heat. It is based on 60% efficiency (for class AB amplifiers) and a battery voltage of 13.8 volts. }. Diameter = .1*1.123^6 They express it in square millimeters(mm2). Since the 10g wire has an approximate diameter of .1" or 100 mils, we square 100 and get 10,000 circular mils. if (eval(document.volt_drop2.circular_mils.value/document.volt_drop2.current_flow.value) > 300) This shows that the wire would dissipate 14,400 watts of heat which would melt the wire's insulation and more than likely ignite everything that comes in contact with the wire (fuel lines, other wires, carpet, plastic, insulation). document.volt_drop1.resistance_circular_mil_foot.value = Math.round(document.volt_drop1.resistance_circular_mil_foot.value); Solid Wire Table: Length is in feet. If your amplifiers don't have internal or on-board fuses, use the manufacturers suggested fuse in the distribution block. When this happens, all you can do is stand back and hope that the wire burns open (to break the circuit -- like the correct fuse would have done). document.volt_drop1.current_flow.value = (document.volt_drop1.current_flow.value/10); if (eval(document.volt_drop1.wire_gauge.value) > 10) battery_voltage = eval(document.volt_drop1.battery_voltage.value); The voltage drop given by this calculator is for one conductor (such as the power wire from the battery to an amplifier). If you have to calculate the resistance of a wire with a significantly larger or smaller gauge (like 4g power wire), you can use the following formula: For 4g wire: Safety: Keep in mind that, in the following description, we are talking about the area of the wire in a circular shape. Get the skinny on our new models. if (eval(document.gauge_conversion.wire_gauge_2.value) <= 10) The chart below is a quick guide for selecting the correct KnuKonceptz Speaker Pant for your application. This model is versitile, it fits most 12 gauge side by side cables and most round profile speaker wire. document.volt_drop1.current_flow.value = Math.round(document.volt_drop1.current_flow.value); For example, copper clad aluminum wire has more resistance and, although it varies, CCA wire for the same diameter can only safely carry about 60-70% of copper wire. { Circular Mils: circular_mils = eval(document.volt_drop1.circular_mils.value); document.gauge_conversion.number_of_conductors.value = ((((document.gauge_conversion.circular_mils_2.value*document.gauge_conversion.number_of_conductors_in_bundle.value)/document.gauge_conversion.circular_mils.value)*10000)/10000); How are you able to offer such a lower price on this cable?

You need to be certain the cable you are installing can safely transfer the load from your battery to your amplifier. Others may suggest slightly different fuses for a given wire size but these should be generally recognized as safe in most all situations. Dry location - household/building wire (generally the first 'H' if there are 2 Hs), High temperature (second H if there are 2 Hs). Using these larger strands means less production time, which translates to a less expensive cable to manufacture. In this type of wire, the copper is plated with tin or similar conductor (maybe a lead/tin or bismuth/tin alloy) which will not oxidize as quickly and never as completely as the bare copper. The two battery terminals are essentially shorted together by the wire (through the chassis). For some conductors like buss bars and circuit boards, you won't have a wire gauge or diameter to use to see how much current a conductor can handle. Max load - 40A @ 20ft, *Core OD estimated, being stranded cable there is no true measure for B. Overview Bassik Battery Power and Ground wire is made from 32 gauge stranded, copper clad aluminum (CCA) conductors. if (eval(document.volt_drop1.wire_gauge.value) <= 10) Components such as Battery Power and ground cable, RCA and speaker wire are just a couple of the included parts required to complete your amplifier installation. < /RANT >. { // Calculating the difference in wire gauge input and 10g wire.
