Glue wise - You need a industrial Strength self leveling adhesive. More that likely you can find this a HD, Lowes or a craft shop. Add pressure to the spot for 24 hours to ensure bonding.

Tinsel Lead - Run to radio shack and grab some Desoldering Braid (http://www.radioshack.com/product/in...ductId=2062744). This can be used a Temp fix, until you can get the correct Tinsel lead for your Sub. Cover the Desoldering braid with shrink wrap for added durability (Be careful)
