I have 4 Hertz SV165’s in the front fairing along with a set of st25 horns. I just installed a set of HCX690’s in my bags. I have 2 Diamond Audio micro 4v2’s with a Alpine 149bt. Do I wire all 4 6.5’s to one amp and the the 6x9’s and the horns to the other? I have been told to wire the 6.5’s in parallel. I’m confused on which way will sound the best.
