2001JeepGrandCherokee Posted July 16, 2008 Report Posted July 16, 2008 Yesterday i built a box for 2 12's, it is 4 cubes after displacment and port. When I turn it up i can see the box flex and make horrible noises. How do you think I can brace it so it has no more flex? Any input will help! Thanks.
