Outside engine compartments the ambient temperature should generally be 20 c.
Car amp ground wire size. Learn how to properly ground the power ground wire from your car audio amplifier. Ground cables should be the same size or larger as the power cable. Distribution blocks on negative and positive or just positive or non.
If it maters cx300 1 with 2subs kicker dc12 kx400 4 with 2 kss650 and 2ksc650. The ground conductor size calculator will calculate the proper ground conductor size for grounding raceways and equipment based on ampere rating or setting of automatic overcurrent protection device in circuit ahead of equipment. If distribution block what wire size before and after blocks.
Car frame material has a larger resistivity than a copper wire car frame has many materials connected such as rubber so ground current may have to bounce off several materials to make it back to the battery ground other devices are using the frame as the ground so maybe it could cause some interference. National electrical code nec 2014 edition table 250 122. So for a four gauge wire that is fifteen feet long you would get.
Ground wire size table source. Although wire gauge sizes smaller than 10 gauge may be acceptable for the amount of current draw we recommend using 10 gauge as the smallest wire size for any amplifier of 100. Current draw figures are based on rms power of the amplifier with a 50 efficiency rating.
E 50 0 0037995. What size power and ground wire should i use. Choosing the correct gauge automotive wire depends on the acceptable voltage drop length of the feeder branch circuit conductor load amperage and the ambient temperature of the compartment where the primary wire will pass through.
I have a kicker cx300 1 and kx400 4. This is based on nec nfpa 70. E 0 189975 volts.
Or basically a 0 2 volt drop which is perfectly acceptable. What size amp fuse do i want to use. Now if you have an amplifier that draws fifty amps the voltage drop at maximum current draw would be.
How to calculate the power wire size. For a single amplifier install the required wire size has been specified by the amp s manufacturer and can be found in the owner s manual or online. Choose a higher ambient temperature when conductors are expected to pass through.
Dual amp set up. 0 0002533 15 0 0037995 ohms. Total amplifier rms wattage.
One of the most important connections in a car audio system is the power and ground cable that connect the vehicles battery to an aftermarket amplifier. The gauge of these cables will determine how much power can be sent to an amplifier. Using thicker power and ground cables will allow your amplifier to draw the juice it needs from the battery more easily.
