coin tricks?

I'd say anything is possible with the right setup. I'm not sure about the (2) 12's and (2) 10's though. It's a common rule of thumb not to mix subs due to wave cancelation. And it's hard to verify your friends setup without the specifics... make/model of the amps, subs, batteries, alternator output, wiring method, etc... I've vibrated things off of my roof before with (2) 12" DVC's and 1000 watts, but jumping a quarter over a foot would be impressive if it is possibleSquirrel

Anything is possible; if he is your friend I would have him show you his little trick. But I would not suggest you try it on your own car. Anything you put on the paint surface is an abrasive and will scratch it.

Had a friend learn that the hard way when he decided to use a brillo pad to clean some melted-on silly string after his wedding! ((())) Swirls look cool in a black clear coat (although he wasn't as amused at his mistake!)Squirrel

yeha i cant contact him to ask him what his setup is i moved away recently, but has anybody else been able to achieve bouncing a quarter without throwing it first, like from a resting spot on your truck, hood, or roof?

Honestly I've never tried a quarter on the hood. Water bottles on the roof yes, but not quarters on the hood. I can already tell you that my setup could walk it off the side relativly easily, but could not make it bounce a foot from the mere vibrations. I would almost think that kind of SPL would cause the windows to burst at a minimumSquirrel

considering the air pressure is in the cabin, I'd find it hard to believe it bounce off the hood up to a 1'.  The roof or on a car the trunk lid I can see it bouncing but onlike an inch or two if that.  In the middle of a roof with no support maybe a few inches.  To bounce it on the hood 1' you would need to blow out the windows then somehow have the ports hit the botton of the hood, and with max air preasure thumb the hood hard.  With my old car and the angle of the ports I used to be able to take an empty 2 liter bottle with the cap on, and shot it out the port and right out the car window, landing about 15 feet from the car.  Was pretty neat, but not to much impressive because it was empty and that's what the port does, though to a non audio person it is an awesome trick.

there is a movie at adireaudi.com of one brahma 15 in a ported box wit 1500 watts going to it and it is hoppin about 6 quarters pretty far off the roof of an explorer but i dont think its a foot and its  sure isnt the hood either. has anyboyd seen this??
