[QUOTE="brian84corvette, post: 8228339, member: 586635"] also question - but have you tried using silly putty around your sub when you mount it ? i find that using some sort of sticky type removable sealing ring around my subs will help prevent air leaks - and or also any slapping sounds from contact between the actual woofer and box i see 4 bolts on your box to hold down the sub. is that it ? your only using 4 bolts ? or are there more that i just dont see for fun and also to rule out mechanical woofer failure- take it out of your box - and play it low power in free air. listen to the sub listen for mechanical noises that would seem totaly out of place. agian play in free air at low power please. with the sub out of your box - id suguest trying to caulk the inside seams. every single one. i had a custom box made before in my vette for a 18" re sx that i fed 1200w and it slammed for a good while before one of the rear pannels on my box decided to come loose inside near my port and start rattling around in there during bass notes. sounded dang awfull like the sub was toasted. sub was fine - the box itself was coming apart with rattles of a wood joint loose slapping together. so have fun trying to figure it all out - its a hobby for fun. also dont rule out interior pannels vibrating on eachother making ugly noise during bass notes. there is a multitude of products and tecniques to help eliminate rattles and vibration noises inside the car and outside the car [/QUOTE]
