I would follow the calculations and set the voltage to the right amount at the maximum I want to turn my hu up on but when I start playing the subs at that volume its barely heard. My speaker amp plays loudly at that volume no problem but the subs dont even sound like they are trying. Just got done retuning my sundown 1200D and it says it should be around 35-36 volts. I hooked up the DMM to the channel turned my HU up to 35...and turned the gains up to 37 volts...no loudness on no bass boost nothing is on. I hook up the subs and it barely moves unless I turn the bass boost on. What is going wrong here????Subsonic filter is set at 25hz....box is tuned to 35hz....low pass filter is set to 125hz on the HU and I believe 150hz on the amp...</blockquote>
