Right now I have a Kicker 750.1 amp in my trunk running of a 4awg to the batt. I am going to be adding a Kicker 250.2 amp in my trunk in the next couple of days. I want to get a distribution block so I only have one cable going to the back. The only shop close to me only had 4awg to 2 8awg blocks. Will 3ft of 8awg cable be sufficient for a Kicker 750.1 amp?
