Lately (about the last three months) at lower volumes (0-12 on my Kenwood) my subs have been extremely distorted or haven't even played. Last night I completely rewired my harness, soldering it this time as apposed to the butt connectors I used during the install. It fixed a couple problems the head unit was having and helped the distortion a little, but it's still there... what's my next step? Find a new ground for the amp? I checked the fuse holder a week ago and it was burned together and fused...
