You stated utilizing a JL 500/1 amp and the subs were in a sealed enclosure. That may sound pretty good but 250 watts a sub barely enough for them and claim to shatter glass is just a bold lie. Being into car audio a long time, I've had many set ups before. Yes I said I've used the subs BUT....I had a 81000D (MTX Audio) pushing mine. Why didn't you port/vent them?? Mine were sealed as well, 2 cubes each. You failed to mention what kind of vehicle they were in. Mine were in a S10 blzr. You failed to mention what kind of glass you shattered....certainly wasn't the windsheild, unless it was already partially busted and you busted it all the way claiming you "shattered glass". It's clear you've never heard of Resonant Engineering(aka RE for short) nor DD(Digital Designs) otherwise you wouldn't be posting the best loudest subs you've ever heard. Don't get me wrong, the 15w3 is an absolute aesome sub....but there's better out there, trust me. So before continuing the BS and making people out there believe this tall tale, you may wanna change your story a bit. Now, if you had about 8 more pairs of 15w3's, then I might believe you. Oh and by the way, the RMS on them is 400, NOT 300. Oh I'd love to see what Scottie Johnson has to say about your little
ebay auction here. I bet you have no idea who he is do ya? He had 9 15w3's in a Safari....or Astro can't remember which.
