I work as an electrician and have enough 4 awg copper thhn stranded electrical wire to run from my battery to the amp I am going to install. Could I just use that instead of buying some EB Flex? Is there any downsides?
We can safely assume you know how to use ampacity chart and #4 is adequate for your amp(s). The main difference in "car audio" power cable is flexibility and sometimes better/thicker insulation. Just be mindful about putting wire anyplace where it might flex or rub on something, otherwise, copper is copper and electrons really don't know the difference.I work as an electrician and have enough 4 awg copper thhn stranded electrical wire to run from my battery to the amp I am going to install.
