I have had my H-100 for 2 years and 1 month, sux 1 month out of warranty it is having issues. If i have the volume very low it seems to be functioning, but at and normal listening levesl all it will do is hum (best i can do to explain). This seems to happen at about 36 on my onkyo receiver. But even before it starts to malfunction it doesnt seem to put out the volume that it should. I have tried different inputs and different cables to the sub and different power outlets. Any idea what the issue is ? Anyone have this issue? Anyone have experience with trying to get BIC to help when slightly out of warranty? Also where can i get a replacement amp, wouldnt mind getting the same amp it came with.
