lol, your funny.. If you wanted the loudest system, you wouldn't use only 12volt batteries... you would use batteries for the amplifier rails... lots of batteries in series to get lots of volts... not lots of amps.. see... so, only a really STUPID arrogant person would need 8000amps.. lol

yet another example of you guys talking about stuff you dont know about.. listen. like an compeietion there are rules. the rules in db drag racing is the car's system voltage can not be above 17.9volts dc measured at the alt's/batteries. in order to get more power you need lotsa amps obvisouly, and to minimize voltage drops 2"x2" (or larger) solid copper bus bars are used. here is an example of a car that has a decent amout of work done.. 72000 watts continous

and if youd like to see a video of what 170db does to a car, check here

although many people on this board are knowledgeable when it comes to how to build amps, and speakers etc... you all dont know jack when it comes to db drag racing---so please tell me another one.

its not 170db in the room... it is inside the van which are usually damped with tons of concrete--if any sound gets out, its sound that isnt inside---so they go thru alot to keep it in there.. the windows are all 2-3" plexi glass. and yes 8000 watts per sub. thermal ratings on subs are for long term performance, if you 'burp' the sub for 1/2 second, they can take quite a bit and not overheat---especially if they are desgined for high excursion/spl subs---check out the DD 9515 sub

Yes, I believe you, I just like arguing... its pretty pointless though you know.. lol and more subs with the same total power would be louder..... umm, also, what frequency are those 9 15inch Brahmas played at? cos thats another point.. lol and, the cabin of that vehicle is soo small.. lol

the frequency chosen is usually the resonant frequency of the cabin and usually around 40-50hz, anyway u can stretch a few db is the way to go. this isnt for music--its a loudness competition

is it anymore stupid than investing 10's of thousands of dollars in a car to drive solely down a striaght 1/4 mile track?? it is a sport, and just like any sport there are people who enjoy doing it and enjoy watching it -- and its not easy. different ppl enjoy different things. i dont believe they shoudl be bashed for that
