Amp kits Overated?

[imaspaceguy90 10+ year member]

DO manufacterers overrate amplifier wiring kits? I know diffrent brands and models of kits use diffrent types of wire and thread count.

I bought this amp kit that says it does 2100w

Its a 4 guage kit. But this is also a 4 guage kit and only does 500w

yah the ratings are all over the place... you can do the math (don't remember all the equations right now) to determine how many amps your going to draw and then each ga of wire has an ampacity (sp?).... or you could look at this... it seems legit ratings

there has been some debate as to the legit size of a cable and its useful ampacity (current carrying capacity). I grabbed the following table that assumes a 15 foot cable run and allowing less than 1/2 volt drop over the run.

0 awg 334 amps 2763 watts

1 awg 265 amps 2193 watts

2 awg 210 amps 1740 watts

3 awg 167 amps 1381 watts

4 awg 132 amps 1096 watts

5 awg 105 amps 870 watts

6 awg 83.4 amps 690 watts

7 awg 66.2 amps 548 watts

8 awg 52.5 amps 435 watts

9 awg 41.7 amps 375 watts

10 awg 33.1 amps 273 watts

11 awg 26.3 amps 217 watts

12 awg 20.84 amps 172 watts

13 awg 16.54 amps 137 watts

14 awg 13.13 amps 109 watts

15 awg 10.42 amps 86 watts

to get a rough estimate of the amps you are going to draw i use this, http://www.bcae1.com/wire.htm. scroll down to the middle and under system design assistant. just basically read that whole section to find out what kind of wire you need.

They're not bad. All my power wire is audiopipe cause I got a good deal on it. As long as you know what size wire you need and go with that rather than basing your choice on manufacturer's "ratings" you'll be fine.
