ok...i am one of the people not knowing whether to laugh or cry at some of this
A) Boss Audio...the 3000d is overrated true...but for the price it does a clean 1200W. as for his 1200W boss amps...yeah, prob around 600-700 actual watts (but again, for the price not bad).
B) If i ever met a shop owner as beligerant as bigdaddy they would lose my business in an instant. If it's not how you meant to come across i apologize. At what level were these vehicles you built winning competitions? if national, who were they? What kind of scores were they getting (SQ and/or SPL)?
as for the Quadrature and X-Audio...i'd have a hard time believing in a company who states some bogus stuff on their website. One of which is the fact that a wall outlet puts out DC voltage (yea, i had to check their site too...seeing is believing

it's on the tech page in the white box with the waveform graph)...
or that they reinvent the wheel by saying they understand the difference between REAL RMS and FAKE RMS and have come up with their CONTINUOUS TRUE POWER (CTP). what the heck is the difference between that and real RMS? then they say the real reason subs are overrated in power handling is because they know the consumer doesn't have access to test equipment to prove a lying company wrong. Apparently they aren't too aware of what's available to the public...
third, you are right...install plays a huuuuge role in resulting output levels and quality. and i have heard some walls with lots of cheaper subs and they did sound very loud and some metered decently...but this entire response by you:
"real installers make it happen, people who think they know what they are doing can only make a super loud system by spending a ton of money on big huge amplifiers, and monster subs then you dont have to think you just buy and put in in because regardless you know it will sound good. Why not use your brain and make something happen use the basics of electronics and show your talent buying subs that are 600.00 dollars a piece you cant go wrong but for what i spend on 12 subs carefully chosen to my perfection i spend less but i sound way louder than you 1 600.00 dollar sub do you get it if not go to school and learn a little bit more and then come talk to me!"
are you sure you want to stand beside that statement? I know some people who would argue very strongly that they only have huge amps and monster subs to hit big numbers (all without thinking...). and i can think of some $600 (and cheaper) subs that could hang with your 12 subs. and as for the education part...no comment. Some strong words and statements you're making...better do YOUR homework before saying stuff like that.
here's where you said you did competition: "i have been doing it for eight years and won many competitions", think it was your third response, maybe second. and in the same thread:
"bigger woofers more air more money, smaller woofers cheaper, but you need more than two!"
so um, buying more than two...wouldn't that be like buying a more expensive sub? I think i know what you meant but it didn't come out right.
what mic were you doing a 163 on (that was your vehicle right?)?
and i've never heard of the memphis 12" DD's and we sell memphis at our shop (good stuff imo...the HPO's jam

)...how old were these subs? sure you got the model name right?
or this statement: "whats funny is i can take 2 12's and make it hit harder than my 12 10's im tellin you it does not take a genious!"
so you're saying it takes a genious to make 12 10's loud? Kind of like saying it doesn't take a genious to make a 4 cylinder fast while running a stock V8 yourself...where's the genious in buying a fast, stock V8?
dwh and gsteg were right...for what the consumer would pay for those subs they could use buy much higher quality subs, a nice amp, and with a decent box (with less space) do just as well as you. Sure...nice to see loud setups with many subs, but it's more impressive to see the same thing from a fraction of the speakers (matter of opinion...prob).
