most people run a power wire to a distribution block, and then that splits into 2 power wire, one for each amp. run your remote wire back, and most will just tap another wire in to that and run it to the other amp, and ground them both, and your good. and for your rca's use y-adapters, or your rca out on your amp if you have one
my problem is all of a sudden my amps went out... and sometimes the amps come on but one is seeming to be getin gmore power then the other. both will come on the one on the left, the status light will start to dim then the one on the right will dim behind it and they will go out one after the other. but if i take a wire and tap the 12v power and the remote wire screw on the amp the amps go completely out and when i take it off they come back on att full power and then back to problem 1
