i have the mrd-m605 amp. one person on here has told me to not adjust the gain over 2v, while another person said it should be more around 4.5v. I have a type r 4ohm dual voice coil subwoofer @ 2ohms, with an alpine 9847 pre-amp @ 2volts. when adjusting the gain i get hardly any sound from the subwoofer at 2v or 4.5v, the input ranges on the amp are from 0.1v-8.1v, the question is where exactly should this amp gain be set at, I crank the unit to about 25 and have the defeat on, and still can not pick up any distortion when adjusting the gains. It seems to only have bass at 0.1v-1v, after that the bass disappears, or the bass function on the head unit, and subwoofer have to be cranked to hear anything. any more input would be appreciated.
