When i add my 2nd amp this weekend 1st is a jl m 6600 and the second is a kicker zx 450.2 do i run a dedicated ground back to the battery from each amp, or can i "jump" the ground from one anp to the other then to the battery.
Also for power i was going to run 4 ga to the distribution block then run short 8 ga wires to each of the amps. any problems with that??
