Review on Enhance Your Car's Power System with InstallGear 4 Gauge True Spec Power/Ground Wire – 25ft Blue & 25ft Black Soft Touch Cable by Eldrick Carlton

Good deal I just want a little help with the wire size really needed, all car radios will tell you to use 4 gauge or larger for my 750 and amp rated should choose from 1200 watts. 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. I then researched further on the metric needed for the number of watts used and found this out by reading the work of two different engineers - real geeks who understand this and are not trying to boost sales or over-hype the product protect - that really 8 meter is very good for my application - the proof is that nothing heats up, 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 your 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 ranting is 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. Again, the true RMS value is well below 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 will be using, then feel the cables and connections 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.
