I think I am reaching the limits of 4ga power wire . . . do I need to upgrade to 1/0?

By clean up, I meant make it look more organized. Its not like them each having their own ground will make your system 'quieter'. Theoretically, your doing the same on your power wire, so its not like your restricting electrons.

Give each of your amps the same ground.

Take the ground runs from each amp and put all 3 on the same bolt.
