I have one amp rite now using 8 gauge wire "200 watts". I am going to be using some subwoofers and getting a second amp 4 gauge "1200 watts". Now I usually see people using a distribution block. I have kicker battery terminal that will give me 3 outputs. Can i use it to the battery with 2 amps. the third output will be from getting ready for the big 3 upgrade.
