i just purchased two 15in audiobahn subs and one of them when tha stereo is very low has a dinging noise.When you put just a lil pressure on tha lower left hand side it stops and when you turn it up it still bumps loud as hell.Does any one know what this could be.they are brand new so it cant be blown.Also when you put just tha slightest pressure on the top right hand side it makes tha dinging noise very clear and louder.They are tha ALUMX series subs

It sounds like you need to tighten the screw in the lower left hand side, if that doesn't solve the problem you could have a *very* slight gap between the sub and the box.
