Kevin,

I rarely turn the volumn way up for extended periods because I primarily want the power for the lower volumn quality. So when I crank it up it is only for short periods. With that said, is there any advantage to coming off the battery with the 4 gauge or bigger and then splitting at the disblock with two more 4 gauge runners to the amps? Or is the 4 and 8 gauge combo adequate? The Sony amp uses 3 40 amp fuses and I'm not sure about the Rockford Fosgate because the fuses must be under the primary cover which I have never removed. Also, I have not installed a capacitor yet either. After adding this Sony I may have too.

Thank you

BBusbee

if your current draw is more than 80 amps between both amps then you need to run 0 awg. you can run that from the battery and split that with a distribution block into 2 4 awg for the amps

what!?!?! you want some??

running the 4/8 ga combination should work for those amps as long as the 8ga run is kept to a minimum.

That's wrong. 0 AWG cable is good for up to 350 amps. 80 amps only needs 8 AWG to support it. Check the Power and Ground page on this site before you spread bad information, please.

The Rockford Fosgate draws a maximum of 60 amps and the Sony draws a maximum of 120. That's a total of 180 amps so based on the Power and Ground Cable chart I would need to run a 2 gauge wire. Should I come off the battery with a 2 gauge and then split into two 4 gauge wires or should I run a 0 gauge and then split into two 4 gauge wires?

This should be the end of this problem. Thanks guys for all of your help!
