Review on InstallGear 4 Gauge Red 25Ft Power/Ground Wire True Spec And Soft Touch Cable by Shane Minter

Good deal I just want to help a little with the size of the cable I actually need. Any place where car stereos work will tell you to use 4 gauge or larger for my 750w and 1200w RMS amps. And I installed the 4th gauge first, and it seemed inconvenient to install and hide it. But the wires were always freezing, so I know they weren't stressed at all. Then I researched further about the size of caliber required for the wattage used and found out by reading the work of two different engineers - real geeks - who understand and don't try, boosting sales or overprotecting the product - which for my application is really a lot of good caliber 8 - the proof is nothing gets hot, not even close, no wires, no connections. This is because not all charts take into account the length of the cable or the actual wattage used. You can easily calculate the length of a wire by simply measuring it. does your amp use - like one of my amps that says it has a max power of 1500w and an RMS power of 750w, it has 2 x 25A fuses. That's 50 amps together - multiply that by 12 (the volts your car system is using) and that gives you the absolute maximum power my amp can put out before the fuses blow. In my case it is 600 watts with this amplifier. Now we have a real (maximum) wattage to work with. But let's not forget how you listen to music, and in my case I never crank the volume to the max. I know I use 500W max and much less for True RMS. And now my ramblings are almost over. My other amp is listed as 2400 max and 1200 rms. It has 2 40 amp fuses. It has a true max output of 960 watts and in my use it's an actual max output of 800 as I never go above 85% of max volume due to distortion at max levels. Once again, True RMS is a lot less than 800, actual watts put through the cables when listening to music for long periods of time. Hope that helps. Again, in case anyone doubts. Run your system for a while at the maximum volume you will be using, then feel the cables and connections near the battery/amplifier. If anywhere feels hot, you're not getting the most power out of the amp and will need to use thicker cables. Not to mention avoiding danger. It has a true max output of 960 watts and in my use it's an actual max output of 800 as I never go above 85% of max volume due to distortion at max levels. Again, which makes the true RMS much less than 800, the actual watts that are being put on the cables over an extended period of time while listening to music. Hope that helps. Again, in case anyone doubts. Run your system for a while at the maximum volume you are using, then feel the cables and connectors near the battery/amplifier.

It has a true max output of 960 watts and in my use it's an actual max output of 800 as I never go above 85% of max volume due to distortion at max levels. Again, which makes the true RMS much smaller, over 800, the actual watts that are being put on the cables over an extended period of time when listening to music. Hope that helps. Again, in case anyone doubts. Run your system for a while at the maximum volume you are using, then feel the cables and connectors near the battery/amplifier. If anywhere is feeling hot you are not getting the most power out of the amp and will need to use thicker cables. Not to mention avoiding danger. Here, too, the real RMS value is well below 800, the actual watts with which the cables are loaded over a longer period of time when listening to music. Hope that helps. Again, in case anyone doubts.
