This thread is a joke. I wish I was a mod so I could delete it. This is the type of **** they should delete.

i agree, unless he gets some pics. hopefully they will develop soon.

hahahhah. That's so freakin rediculous. What is that a solo X 18". Dude im sorry but there is no need for that setup. It must sound like complete **** and youre gonna go def in about a month. Some people..... lol
here's his pic cuz there are some people who still dont know how to post pics

i think im going crzy. I coulda swore I just saw the kid post his link to the pic nd wut not and now itz gone. It should have been above my post.

ill take some better pics this was at 4 am. the rockford is the 800.4 the sub is being pushed by right around 4400 watt rms. the box was put in by building the sides then fiberglassing the trunk to the box then on goes the top with the sub

Mines_Better

damn that is big!!! i hope you did some serious upgrades to the speakers inside the car so that it sounds better.

diablo2007

yes im gonna go def and it does sound pretty good it hits every note just the same as the 2 jl w7s i took out to put this in. just to let you know im new to this whole internet thing so theres no need to be an ...

rickyw

i doubt it highly that it hits like two jlw7s two 12s will displace more air then that 18.......and sound better because well there jl

impulseballer

lemme ask you a question. I'm guessing by the picture your're running an ma audio HK4000D amp. Well if you are, how are you getting 4400 watts rms out of a 4000 watt rms amp lol. Granted thats alot, that shitty sub needs all that power to move at all. Stop trying to act like your the biggest and baddest out there because you just sound like a ******* boasting about a retarted setup.

rickyw

^^^^^hahahaha

Mines_Better

geez, built up anger?

rickyw

i think hes tired of seeing all these stupid system set ups. I use to work for several custom shops and for tweeter and best buy and i hated people comming in saying oo i have this 18 and it hits hard as heck no 12s can touch it and then i play 1 12 thats better then theres and there like ****...............Ill post my setup in a bit

impulseballer

yes you're right but i think i was a bit too harsh. But i just can't stand people that think they know everything or try to get attention by doing senseless things. It's like when i used to belong to a 3g eclipse forum for my girls car, this kid just posts titled " i have a twin turbo eclipse and its the fastest out there." I dunno i just get sick of people doing that and the audio peeps who just throw in the biggest thing they can fit without doing some research. Granted my system isn't the greatest atm because I'm going for performance first then audio, my 2 12's dont even have 100 watts rms going through them yet the sound is incredible and clean as **** because I know my stuff. Plus I have them in a bandpass box so all the bass just stays in the car basically.

rickyw

Heres my system WHAT NOW i got the biggest ***** of them all


6x jl1000/1
1 MTX JACKHAMMER BIOTCHS


and its custom molded into my truck and the amps are custom molded into my boddy

rickyw

Plus i get a nice boost when the bass hits i also nock all the other cars behind me away

hahahahah...i almost just shat myself

Correct me if I'm wrong, but you MAY need a wheelie bar!!

18" x 18" = 324 square inches.

6" x 6" x 3.14159(pi) = 113.09724 x 2 subs = 226.19448 square inches.

Think about that for a second. After 120 dB, does SQ really matter?

rickyw

he only has one 18 plus the response on the 12s will be better then the response on the 18s your moving more mass with the 18 then you are with the 12s theres an actuall program that will show you the amount of air you are moving. and you right at 120 the sound of the bass doesnt matter but at the lower volumes it does. also if your like me you like to here it on the outside of the car.

also if your like me you tend to get use to the higher db sounds the last car i worked on had 3 jlw6v2s with 1 high capacity amp and some focal components up front and in the back with a high compacity 4ch amp running those. Trust me that probably went way past 120db and damn i got use to it

aj_92rs

I used 18" x 18" because that particular sub is 18" square.

If it was round it would be 9" x 9" x 3.14159 = 254.46879 square inches.

Did you not catch that part?

Besides, you would still be moving more mass with just one 18" round sub than two 12" round subs, and that's how you obtain higher SPL.

E.G. A 12" sub with 200 watts fed to it will put out more SPL than an 8" with the same 200 watts, all else being equal.

The reason I mentioned 120 dB is because it's obvious that anyone who's using an 18" square sub usually isn't interested in SQ. They'd more than likely be interested in SPL. 120 dB was just a number I picked out of thin air.

Also, no. I don't like to hear my stereo on the outside of my car. I like to be sitting in my car when the stereo is on. The imaging sucks when I'm outside of the car.

Now one kicker 18 in sub which cost 1600 roughly with 5000wrms has a diameter of 16.77 will put out 48in(cubed) of volume displacement, with max excersion being .22 in and a impressive surface diameter of 221inchs sqaured(because its not a circle its a square). Also the response is a little low becuase of the huge amount of surface space.

Now a 2 jl w6v2 12s will cost you 1000 roughly 800 rms with a diameter of 9.95 per sub will put out 101 in(cubed) of volume displacement with a max excersion of .65 and a surface diameter of 155.6 inchs squared. Now lets take one sub and find out the surface area of that shall we? Thats 77.8in now because you have a lower surface area your going to have a faster response. times that by two and you will get more space being moved at a faster rate then that 18in SQUARE sub will do.

This is a comparison mainly for the VOLUME DISPLACEMENT.


Now back for to the fun My sub
will put out
6000rms
has a diameter of 18ins
surface area of 254.5 inchs squared
xmax of 2.4 in and will displace 610.7 inchs (cubed)

rickyw

Didnt catched that it was sometime between me reaching for my drink and going to take a ****. so i probably wasnt paying much attention to it.

Your also right the imaging does suck on the outside but when your hanging out with friends in a parking lot blasting your music who cares. Some people also like having a little bet of extra in it just in case. Its kinda like horse power who the hell needs 500 whp when half the time your only going to use half of that or 1/4th of that? Because when the chance arises you want to have that 500 whp at your foot. same thing with having a Highly powered sub. I am all for clarity havent you seen the setup im going with let me find the link and ill post it.

He gets 4400 wRMS with the HK802SX. It runs the amp at 1 ohm because the the sub has 2ohm DVC bridging it down to 1 ohm.

MA Audio HK-802SX 4400W 2 Channel High Current Amplifier
Features:
2 x 500W RMS @ 4 Ohm Stereo
2 x 800W RMS @ 2 Ohm Stereo
2 x 1400W RMS @ 1 Ohm Stereo
2 x 2200W RMS @ 0.5 Ohm Stereo
1 x 4400W RMS @ 1 Ohm Bridged
Dimensions (H x W x L): 2.7”x 12.4”x 27.3”

Also about the surface area
This is correct. 18x18 is the surface area of a square, while (Pi x R^2) or 6x6x3.14 is the surface area of a circle...but it should really be 6.5 because the w7 is a 13" sub not a 12. That brings the surface area of the 13's to 265.464355 a little more than the single 18.

It is also not correct to assume that a larger sub has a slower responce time than a small sub. That is just not true. Most people assume this, but I could build a paper sub that is 20" and it would have a better responce than a 8" sub that has the cone made of forged steel. (I know this isn't a RL comparison it is just for example of why this is not a correct assumption.) There is alot that goes into a subs responce time. I am not going to sit here and pretend like I know it all but I do know that size is not the only factor. Air space of the sub's enclosure makes for better or worse responce....

Oops was a little late, oh well.
