right in the boot i will have two active subs and two pheonix gold QX amps. So 4 amps. Is it best to split power and earth into each one individualy or split into 1 amp and 1 sub sub and then bunny loop (i think its called) accross to the other sub and amp. cheers.
you should run either 1 run of 0 gauge wiring to a distribution block then to each amp or run 2 x 4 guage runs to a distribution block very least 1 4 gauge run to a distribution block same for earth really
