Well, come to find out one of my amps isn’t putting out any power. So this whole time One of my subs has only been playing on one coil. So I hooked up just two amps for now. Each 3500 wired at .35 ohm to each sub. Gained over a db by writing up the two amps! Does over a 155 now! I’ll have to pull the amp and take a look. Hope its an easy fix.
