From it, you can see a list of things, including: The 6 gauge wire amp rating is 65 amps for copper, with 167☏ ambient temperature. The cheaper the amp kit, the cheaper and thinner the wire even if the wire jacket looks thick. The NEC, THHN, & AWG wire gauge amp chart is the easiest way to see the amp rating for different wire thicknesses. All these manufacturer’s of the cheap amp kits have done is play a marketing game to make the wire appear thicker than it is by using artificially thick jackets masking a small wire inside the jacket. Also, some of the cheaper amp kits use a heavy thick insulation over the center wire conductor, the actual wire, making the wire appear heavier and thicker than it really is.
Amp wire gauge chart upgrade#
As a result it’s not a bad idea to either buy a premium wire or upgrade the size of the wire in the amp kit to the next larger size to insure adequate power delivery to your amp.
Amp wire gauge chart install#
Now a days many of the amp install kits you buy have copper coated tin wire which is not the same quality as the pure copper wire once used. Distortion overheats the subwoofer’s voice coils causing them to eventually melt or burn up.)
Car amplifier distortion is the chief cause of car subwoofer failure. (Distortion is a speaker’s greatest enemy. Also a car amp may distort prematurely if it is starved for current and voltage. Too small a cable will reduce the power getting to your car amplifier and thereby reduce the amplifier’s performance, causing it to overheat or shut off. In car wire gauge sizes, the smaller the number of the gauge, the thicker the wire and the more current it will carry over a longer distance with less loss due to the internal resistance of the wire itself. Of course, if youre looking for a new car amplifier, we list the recommended amp wiring kit. Bigger is better, and there is always the possibility that you may decide to either upgrade your amp later for a larger one or add an additional car amplifier in your car audio system. Do a little bit of math and then consult our wire size chart below. Note: This amp wiring gauge chart gives the acceptable wire gauge required, however it is always O.K. wire length column and the 65-85 amp row intersect in a purple rectangle which indicated a 4 gauge wire required for the amplifier installation. of wire for my install column + amp requiring 70 amps max current draw (choose the 65-85 Amperes row) the 16-19 ft. The color of the rectangle where the row and column intersect represents the gauge size you need for your amp install. Follow the row and column you selected until they intersect. Then select the row with the number of amps (current) that your amplifier will use at max power. Select the column for the length of wire you need at the bottom of the chart.

It’d help if you used a 300A ampacity wire or higher. Audio Control Amps, EQ’s & Signal Processors Additionally, to have the proper size wire for 200 amps for that distance, you must raise the amps by 20: 200 Amp Wire (100 ft away) 250A × 1.2 300A Ampacity.
