Question about MA Audio Hard Kore HK-898 Car Audio Amplifier
If there's no sound at all from the subs and you know they are good, there's probably no output from the amp. It's either wired incorrectly or it is defective.
If there's some sound but just not loud enough, then either the amp is not getting enough of an input signal from your head unit, or the amp settings are not adjusted properly. Adjust the crossover and gains for the best output to subs. LP filter on, crossover frequency at about 80-100Hz, and gain to maximum without distortion when head unit volume is at about 3/4 maximum.
Hope this helps.
