So I finally got my sundown sa12 in running of a db drive okur 800.1. Box is 3 cubes tuned to 32hz. Set gain to 40 volts with a dmm on a 40hz -5db tone at 32/35 volume. The thing is barely louder subsonic filter set to 15hz and lpf set to 90hz. Bass boost is 0. The thing is barely louder than my old ID12 which was powered off a kicker kx250, for more than tripling the power I'm not seeing the output. The sub is wired neg to neg to terminal pos to pos to terminal. It's d4 so it should be running at 2ohms. The amp even though its mono has 2 negative and 2 positive terminals. I tried switching the negative to different terminals, no change. Any advice is appreciated.
