That will hurt your ears. I am telling your mother.

i want to get in the mid to high 150dB range, I have to be outside of the car for the leage if its over 150. im going to pannel out the trunk with MDF greatstuff fiberglass and then carpet it all to look stock then throw the box in the box. and Im going to brace up what i can in the trunk, deff. seal it super well too. but the only thing that sucks, is that, that box pictued is 3" too big when i go tp put it in the trunk , reason being is i built it to spec before i knew what i was getting, i was expecting a crown vic or a blazer....

Ok, what ind of box is that?

First thing the port is to small, need more port area.

Then in another picture I can see grass through the bottom? wtf?

Good luck on your quest. We did the 4th loudest bass race car in the world with 4 15's in a 4 door buick and it almost did 156...

I also helped with a single 12 premiere like that a few years back. Good sub, but I dont think your going to be into the 150's. Probably mid-high 140's.

looks like that thing is going to destroy that poorly crafted box like a handgrenade

[bizarre179]

Yeah that box looks way to small, especially for being ported. But Yeah, that is nuts. That speaker is a monster! What kinda amp(s) are you pushing it with.

[Ian 2000GL LA1]

ok the box was unfinished for the pics, lol, and actually it is the recommended 3.25, its closer to 4 cubes internally. they called for a single port of 4" 5.5" deep, so i called them and no one wanted to help, AS$Holes. so i got online and did some calculating, totaled up a few sites and cam out with an average, theres no puffs, theres no excessive air blast it's good, its 18.5" long, 18.5" high and 3" wide. and i rounded the port edge, yes its nailed, but i liquide nails'd it and used alexes caulking to seal everything inside. the night i threw the sub and amp in my mustang, i roughly tuned to amp and metered it at the dash and it hit a 149.4 on a 6 year old stick mic. and it could use nore juice from the car.

[Ian 2000GL LA1]

but the box won't fit the alero i built it before i had it. stupid me....

[Ryan from Ohio]

you need to look at port area, which is the opening of the port.

3 x 18.5= 55.5 sq in of port area. Thats simply to small. I would advise about 75-100 Sq inches.

now you owe me $1.


That works ok, but you need to know what your after. Thats where the battle begins.

Also the stick mic your using is inaccurate to todays standards. Was it an Audio Control? or you talking a Radio Shack thing?

Unless your being metered on a term lab or an calibrate Audio Control dont go spouting numbers. People will rip you every which way... lol... Seen it millions of times. Me, Im not much of a numbers guy. As long as it sounds good to me, then it is what it is.

[DansGen1Alero]

thats about why my JLs did last time i had them checked, at dash, or floor, I can't remember exactly but was like 143.8 or 148.3

[spinalator]

Who makes the best 8-track deck?

[Ian 2000GL LA1]

i know the stick mic is off thats the only reason i pointed it off, its, a great meter idk what kind, i was told it was like $1200 new. the mic was specific for it. and the port area fits the sub fine i did the math with sub excursion, displacment, and so on. i wanted it to be in the 40's-50's for fq to hit differently.

[Fi-Alero]

Nice box, but if SPL is your goal, you built it wrong. That sub likes a small box with alot of port area when it comes to getting loud on the meter.

Also, Aero ports are generally better for tuned ported SPL boxes because they tune at a specific frequency, unlike a slot port that tunes at a range of frequencies. Now if you are chasing the wave, a slot port would be better, but I doubt you are doing that lol.

Good luck getting the score you are looking for man. Believe me, it isn't easy to do 150s in an alero.

[Steven01]

Thats Awsam Im running pioneer premiers 10" two of them with rockford 900 rms amp It puts out a Nice punch.

[Ian 2000GL LA1]

im planning on reinforcing the trunk with MDF panels, greatstuff, bondo(for smoothing) then wrapping it all in fiberglass, you cant get more soldi and ridged than that.

[Fi-Alero]

It doesn't require all of that lol.
All it requires is a correctly built box with the power and charging system behind it.

you have yours layers ass backwards, if you did it in the order.....well, you'd find out.

[Ryan from Ohio]

I think your going overboard here, but eh whatever floats your boat.

Ive been in this hobby for 13 years now. That ports to small for your aspirations. Heck the box is even on the small side. Its a 15" sub, only 3 1/4 cubes? Ive done 12's in boxes bigger than that... I would start looking at graphs in the 5-8' range.

[Ian 2000GL LA1]

what do you mean graphs, shouldn't i be looking for something specificly sized for SPL that mathces this sub?
