Thicker the CPS the better. There is some 2000 CPS stuff on Amazon as well.
Last stuff I bought was local from a hobby sports store for airplanes with massive r/c engines so it was a thick ca glue. It worked on securing the spiders. But I had other problems besides that with the subwoofer so didn't test it out very long. But the owner who sold it to me said a lot of the guys in that area for car audio use it so gave it a shot.
