The wire is a fairly new (-2 yrs) scoche kit. The fuse is all enclosed in a rubberish deal. I figure it may be the amp because I have noticed still having a bit of bass wit my remote switched off. It'* not my speakers, because the bass on my HU is all the way down. It'* also very subtle. I haven't looked to see if my sub cones were moving with the remote off, but I assume the amp is still pushing a little bit.
