had the field covered by 2.x db i hit 144.8 db in a 4 ohm load (would have hit higher had i went into a 1 ohm load but i was waiting to see if anyone hit higher then i did) this was in the 0-300 watt modified class system is 2 alumapro bp-12's along with a single rockford 301M mono sub amp ill post up better pics later,and also full system pics for u guys who have never seen it before ----------

144db is nice with 2 12's! Highest I ever got was 136db with 2 10's in an isoberic bandpass with 400 watts 2ohm mono. Is that front load bandpass configuration?


Congradulations!

sick man , whats the box turn to ?

i quess that would be called a front load, my amp actually puts out 440 rms and just over 950 peak(been modified). but the oem specs are 300/900 and thats what they go by

jtufts to be honest i dont remeber ill look on alumapros site and find out

i just did =)

they turn them for 20-80hz

they look realy nice back there in the seat

lol there not in the seat they completly replaced the seat

thnx

oh i know , i am fighting my self right now if i want to go and get a sealed back seat removed and built sealed box droped in

im debating on building somethig to seal off the hatch area for when i goto my next comp.

i may also ditch the alumapros/enclosures for a custom fiberglass enclosure to fit 4 12's in the same spot, though i would go with a ported box

whats up with the two different types of subs?

Rockford Fosgate Is the shiznit. I have two of the power series like you 1 501bd and a 351m. So now I know what I can look foward to, SPL wise. Are you running an eq are anything before the amp?

congratulations and i like the set up you have going on.

ported is louder than any other type of box imo.. you can tune it to wahtever you want.. dave i would get 4 12" DD 9512's in a ported enclosure.. that would be insanely loud

i had previously blown one of the alumapros, a replacement driver was dam near 600$'s. i couldnt afford it at the time so i just replaced it with a diff sub for the time being
----------
speedracer no i dont have any addon eq or dsp i run directly off my headunit

Congrats....max I ever his was 133 on an IASCA car tuned for sq.

Nice going.

nice job man. must be a pretty nice setup, anybody can buy 15 huge beefy subs and make them loud but not many can take a smaller system and make it loud.

Its excellent, of course, to win any competition. I'm impressed, and I don't doubt the skill involved, but why is SPL such a big deal?

It seems like sound quality is much more important...

~130 dB is the threshold of pain...going beyond that for any extended period of time is terrible for your ears, so why build stereos that put out at such ridiculous levels?

Don't get me wrong, I love loud music - who doesn't - but 144dB?! Damn thats loud.

spl is mostly a big deal just cause its the loudest of the loud,not to mention high spl is not easy to achieve. once u get inot the 135-140 db range it becomes very hard to get any louder.
personally i have my system set to my sound quality tastes,its not just all bass by any means.i never went into an sq comp because it is alot of money to do it and be competitive. i also dont actively do spl competitions, i do maybe 2 a year a local car shows.

yeah its hard to sit in the car with it all the way up, when driving i never play it to full volume i prolly have it down inthe 125-130db range when i want to listen to it loud.

130db SPL is VERY loud! I know I had trouble seeing out of any of my mirrors with my old car that had the system.
