its not looking to good for me right now i was borrowing a camro box from a friend with 2 jl subs and a 1000 watt amp
well he gets here this morning throw the stuff in + what i already have in the car
soon as we get to 3/4 volume the car stalls
to much drian on my batt and alt (pretty much a 150 amp draw just from the amplifiers)
it literally kills the battery and stalls the car after a few good bass hits
i really need a 200 amp alt and a good deep cycle battery to run this setup
so i may just go with the one 1000 watt amp and 2 12's as the car is able to handle that kind of power draw with no problems,cause i dont think ill be able to get my hands on a 200 amp alt today

what a ****** day, we get there and i wire the subs into a 8 ohm load, so the judge comes over and says we have to put u into a modifed class cause ur sub enclosure is past the rear of the door frames,now most of the guys in modified run 4 or more subs and a few thosand watts,so i know right off the bat this isnt gonna be good.so i found out they have a new class that goes on just then number of subs u have.1 = sb1 2 = sb2 etc,now there sno limit on amplifier power so im thinking this is a good idea WRONG. instead of going by peak spl,they take an avg of ur spl over 30 seconds,well here swhat happened.first time up i pick a song with about 3 seconds between bass hits
i start up with 140.2 db but due to the delay between bass hits i end the run with 122.3 db .so by now im 2.2 db outa first place and really pissed.so i park the car and rewire to a 2 ohm load (about an extra 400 watts of power now) and go make another run.now i think im set.well anyways i start the run at 148.7 db except i had left the trunk unlatched and it blew open during my 30 seconds so my avg spl droped to 131.1. good enough for first in y class but dq'ed due to the trunk opening.so i wait a while to see what the reamining cars hit and after a while 1st n the class is 137.6.so i give it one last shot with a diff cd(big mistake) i end up with a peak of 145.1 but an avg of 134.5. 4th place for the event,even though i didnt win i did manage to get my car into a car club,and i really cant be that mad cause 148 db for a car with 2 12's is exceptionally loud.but ive deff got some work to do before the next competition in 3 weeks. i took a ****load of pics and ill post thm up sometime tongiht or tom

well you do realize that distance places a big role when a jumbo jet takes off, **** my airplane shook everytime it would start its take off while i was waiting for my clearance and it wasnt even a 747. now if you stand back 300 feet and listen to it then its not even the bad, i was just wondering thats all.

so techincally your car would be able to silence a 747? interesting. i mean you would be able to hear the jet take off if you stand next to your car.

yeah and its actualyl measured by preasure level inside the car, sound wave actually presurize the car.its pretty complicated but preasure level directly reflects decibal level.its done this way to prevent ppl from cheating by throwing a high powered tweeter near the location of the microphone/preasure sensor , though a car measured in this manner may hit 140 db, thats only the decibal level of the bass, the actually db level of the car(bass/mids/highs) can and in most cases is actually higher then the spl/db reading at one of these events
