2 rd audio heaveyweights and 1 rd audio 3250.1 at .5ohms box will be 10 cubes before dissplacments port is 100sqin tuned to 36hz so is 150.dbz possable in a hatchback?

With that power i'd get something that was a bit more efficient for that power. Something like a DC LVL4xl would be really good with that power, granted it would laugh at it daily but still get loud.

Look in my sig, i only have 3500 or so watts going to a pair of 12" LVL4xls in a trunk car and am extremely close to a 150.

efficient?

What efficiency are the LVL 4 XLs... if there not above a 94 there not near as efficient as the HW from what I believe

Not in that way, simply handling the power wise efficiency. HWs need alot more power to get loud than LVL4xls do, thats what i was going for.

my port i will be doing is 4"x25"x14"deep will this produce port noise that is the only way to get to 36hz
and will moving the box back and forth change my cars peak when i had my 12's in i peeked @42hz but now with the 18's im peeking @32hz same car but bigger box
any help please im goine a comp sunday and wont to know before i cutup my port

Just make sure everything is rounded over and if u can resin the inside of the box to give it a slick surface.

thats only about 10 in^2 per cu ft.... you should be around 16 in^2 per cu ft...

dude you guys are so clueless when it comes to power an subs. the lvl 4's are made for ground pounding that is why it don't take much power to move them. the hw on the other hand was intended for spl an some qround pounding i think. they need more power like the earliar poster said they do need more power. now the 3250 at .5 ohm load does about 3400 watts i think i am not for sure but i would check it out on rd site for sure an make **** sure you have the electrical system to feed that lil monster.
what size subs are using by the way. 12's 15's what. if 12's i think 10cubes is seriously toooooooooo big for 12's an about too big for 15's. i have seen guys put a 4 cube box in an suv an pop 150 with 3500 watts. but testin an testin an test would help fo sho.

18's im getting 1 more 3250.1 as soon as steve call's me next week i hope and im running the 1 i have at .5ohms now and tuned to 32hz and my tires flex as much as my windshild lol but i wonted to know about the tuning it to 36hz by cutting my port down for a comp sunday but im going to have to make my port 14" deep aposed to 21.5 and i dont wont port noise or hurt anything by doing it
her are the specs on the amp but @ 0.8ohms and i running mine at .5 so i dont know

dude its hard to tell, i mean i have seen guys do 50's at low freq. i heard of a guy doing it at 28 hertz not sure if its for real but i heard about it. logically higher tuning is for spl but with my setup its tuned high but it gets down an get the lows pretty **** good i think soo. i would say with 5600 watts an the subs you have i would say that its do able. but you really need to test cause if you can get a 149 out of it as is i can almost promise you its a 50 in it. sometimes its just the matter of finding it in your box or your vehicle.

TESTING TESTING TESTING TESTING TESTING TESTING AN MORE TESTING.
i think i have stressed that enought to him anyway, that your gonna have to try everything lol like i said you was doing low 50's with 4 10's so i know he can get close with the 18's, but your gonna have to test.

it's going to do about 149.6 @ 47hz so I would try some thing dif.....

Too many variables to estimate a TL score on the sole basis of gear/equipment. Each vehicle has different transient responses in cabin just like a box. The highest numbers you see are all from trial and error. You can estimate a good daily sounding setup, but for strict SPL purposes, you've just gotta dive in and try **** until you get something that clicks.
