I just got a 4ch amp and I only have speakers running from it, no subs (ive yet to install) if I understand right its better to run high input using speakers rather than the rca jacks. in the long run I will be using a portable device. the problem im running into is the connecter looks like this: .----------. |W B R| |W B R| .----------. w=white, b=black, r=red I have two, one on each side (left side ch 1/2 right side 3/4) do I just y split both Bs to be used with the close by W and R and then do the same on the other side? and if thats the case to I then crimp both high inputs to have only one left and right for portable device?
