Ok, My sub keeps comin in and out. I know the source is my inline fuse holder (from a knu amp install kit). How do you guys secure the wire in there? I've tried inserting it then taping it but it falls out, then I took butt connectors, tore off the plastic and shoved that in there...it works but I can see corrosion and it's still not a good connection. Accck help no bass is driving me nuts!
