I don't expect that noise to kill the subs unless it became loud enough to drive the amp into clipping. The amp does not have a subsonic filter, the specs suggest that the effective bandwith starts at 20Hz but it does not say how it rolls of from there. Subsonic more frequently comes in monoblocks. Here are some external filters: http://www.ebay.com/itm/2-FMOD-20Hz-Hi-Pass-Subsonic-Filter-Rumble-Reducer-USA-/ 390358570910?pt=LH_DefaultDomain_0&hash=item5ae32f179e |

I don't think you need them but if you want them there they are. The noise most likeky will remain low but if what is causing it (like a loose ground) got worse (looser) maybe it can become a problem. |

Silver Member Username: Joe1234Post Number: 845 Registered: May-09 | Ok, first the DMM could have issues like low batteries, then you need to look at the RE parameter (DC resistance) on the sub's specs, besides that, yes seems too low usually 3.x is what is expected. |
