PLEASE HELP!! I have just sorted out a new XLR to RCA cable to connect my Denon to my REL Storm (mk1). However, the only way I can get any bass is to have all the gains on both amp & sub turned up very high. Even then it doesn't seem to fill the room with bass half as much as when it was connected to my old Yammy DSPA980!? I have gone through every sound option/adjustment I can find and nothing seems to really bring my sub back to life. Could there be a fault with the amp's sub out? When doing hte test tone I do get a noise from the sub (again with gains up) but its not a 'smooth' rumble (not sure how to explain it), is this correct? Someone help, its driving me mad!!
