need advice i think the rca jacks are shot!

i got a friend who has a hifonics brx2400.1 and when i go to tune the system with a bass test cd and the settings are as follows gain at 11 oclock and the voltage is 9v-0.2v -phase (didnt touch) -bass eq (didnt touch) -subsonic 12 oclock 15hz-35hz so its not playing lower than 25 i assumed (i need a dd-1) and lowpass at 12 oclock 35hz-250hz and it played for about 5 mins and gone!! now the amp comes on and stays on i test with my dmm and i get proper voltage to both remote turn on and 12v both read 13.8v. also i got a funny smell from the rca jack side. am i tuning this wrong or is this amp a p.o.s. need some advice
