is there anyone that can help me with a design for aeroport. Im looking at a box made around 32" wide 15" tall and 16-17" Deep. Tuned to about 32-34 hz (approx box size)

i think im going with SSD's with eathier the flatwind or bp power. Which would you recommend ? I can afford one of them and i know the SSD's now come stock with copper. I also dont like how the HDC is tuned that high, and apparently isnt good with quick bass I get my gains set and subsonic set right so im safe with my equipment. I love how the aq1200d comes with a gain knob that has a clipping indicator. im looking at maybe 3.5 cubes tuned to 32-33 hz. I dont know if i should try a aeroport, i dont know how to tune a box with them. appreciate all your help ! If i upgraded to the aq2200d i would get another battery but i currently have the big 3 upgrade and run 14.4 volts daily.

louder than my current 15" bl in a 3.3 tuned to 32 hz. Im not worried bout the SQ because i know Fi sounds good doing that anyway, but be honest, would the HDCs be louder, keep in mind the SSD's and the HDC's would only get 600 each so many the HDC is to tight since it can take about 2000 rms. Its just tough since i love Fi, would they be ok on a aq2200d? (for future) thnx for your help guys

hey everyone. I currently have a 1 15" BL, but im getting a new car in a bit, so im looking at getting 2 12" ssd. I had a debate between SSD or the HDC. I know a big!! difference but im running them off a aq1200d that i have now so i figured i wont be upgrading power in a while. And if i got a aq2200d do you think i would be safe with the 2 12" ssds still ? Im guessing the ssd would move more than hdc with only 600 rms on each? Do you think the 2 12" ssd will be louder than the 15 BL because of cone area? thnx guys, sorry if they are stupid questions lol

Hey everyone, I just wanted to say, I got my setup in and it sounds AMAZING. I got the 15" loaded BL and bought the aq1200d amp to go. With this i installed the big 3 with 0 gauge except battery to chasis is 4 because i ran out lol.. My battery is stiing around just over 13 volts when off ! and when i play about 14.4 ish. Its in a 3.3 cubic foot box tuned to around 32 hz. Let me say, i have been breaking it in carefully, and wow do i notice a difference. My previous settup was 2 12" jackhammers with a 500 rms sony xplod amp and a cap lol (yes i got rid of the capacitor) It gets really loud in there for sure, while sounding deep and clear, and i know it will get louder, even have some room to turn up gain a bit with the HU. thnx for making an unreal product !

thnx. saving the day once again lol i just need to get one of those damn tone CDs!!!!

hey guys, im just using a temp ported box now that i made using the RE calculator. Its at 3.3 cubic feet for a 15" BL and according to the RE Calculator its set at 32.42 hz. I know its a little unnacurate but what would be safe to put my subsonic filter at. I currently have it set around 30hz ? thnx guys!

perfect.. thank you

I dont know... i know everything was really stiff so i wanted to be safe. so this wont effect the lifespand or anything ? and im going to turn up the gains a bit more on the amp. and yes, the subsonic is at about 28 and my box is tuned to 31 - 32 hz. thnx again you guys are awesome im just gonna try to keep the car cool but im hoping it will only be the magnet and back getting wet.. luckly cant see the rust Hahah but since the sub is gonna be moving air, im sure it will get rid of the wetness and heat. No...whenever we build prototype stuff it goes wide open free air with 2500 watts for a few hours to loosen the suspension in playing at/near Fs.. A gain isn't a volume knob, it needs to be set according to the voltage you are getting out of your headunit. (Play a 60Hz test tone with your RCA's unhooked and verify your voltage with a dmm on AC voltage with the volume where is your "max" that you listen to) If you get 2.5 volts out of it..then that's where your amplifiers gain needs to be set...if you don't have access to an o-scope. Outside of that, you need to verify your subsonic filter with a test CD. Start playing the test cd at 40Hz and go down each track by track. When the sub is moving the least amount, this means you are at the port tuning frequency and the port is doing all of the work. Click down 2 more tracks and adjust your subsonic filter up until the sub doesn't freak out anymore. Once you play under port tuning frequency the sub is basically acting/working in a "free air" environment. alright thank you. i dont have access to an o-scope, so i should read the voltage of the HU which is a Alpine CDA-105 (which does 2v pre-outs..if that helps) and move the gain to whatever voltage the HU puts out? and do you know where i can get the test CD to download so i can burn it on a disc thnx again. appreciate it !

no but im actually gonna be looking into getting that real soon, when i get a couple more paycheques and im gonna do my best to stay out of sunlight, but i am gonna keep windows and seats down when its safe to lol

I dont know... i know everything was really stiff so i wanted to be safe. so this wont effect the lifespand or anything ? and im going to turn up the gains a bit more on the amp. and yes, the subsonic is at about 28 and my box is tuned to 31 - 32 hz. thnx again you guys are awesome im just gonna try to keep the car cool but im hoping it will only be the magnet and back getting wet.. luckly cant see the rust Hahah but since the sub is gonna be moving air, im sure it will get rid of the wetness and heat.

yeahh it really does.. well this is my first summer with a sub, so the humid part is new to me and i havnt ever heard someone talk about it.. I do have the cooling and the flatwind, so it will be good. the coils werent wet at all only the back and a bit on the magnet. the back rusted a bit but nothing bad at all. Still a beautiful sub thnx guys! but you dont think this will effect anything? im gonna drive with my windows open a bit and the back seats down for more cool air. it is a ported box, and my car has no leaks i checked thnx nick ! cant wait for 2 weeks to push it to its full potential.

hey guys,, i got the system setup and working today which was a big relief!! it sounds awesome.. i havnt really blasted it since i got the gains down, so i can warm it up for just over a week to be safe i just have a quick question.. I had the sub in the box for about a week.. we took out the sub today and the magnet was wet, and the bottom of the box was a tad.. it seemed humid in the box.. my car is black and it has been really hot down here, and maybe was just wondering if anyone knows what that could be caused by.. the back piece has a tad of rust now but everything else like the coils and everything were dry. Thnx guys!!

thank you for the video! im getting the system re-installed on tuesday so im praying it works, if not i will for sure do that test and let you guys know the results

I will try this out for sure, im guessing its not the sub since its never been used, but if it is, do i get a refund if its a faulty sub ? thanks for your help scott

yeahhh im gonna try another sub or something lol

well im gonna try to get my hands on one, but the sub was out of the box, brand new, thats why i dont understand why it didnt work

hey guys heres the deal, i finally got my ported box completed and installed the D2 15" BL, hooked up the amp (aq1200d) to 1 ohm, saw that my fuse is blown so i had to use my friends to see if everything was working.. the amp was showing power, and hooked up a capacitor just to see and it was getting the proper volts, but NO response from the sub, no movement at all. We were soo confussed, everything looked properly installed. just wondering if anyone has any ideas! Please help, i appreciate any given. I miss the bass also how do i properly tune my amp, and where do i put the knob angled at on the subsonic, i need it set about 30 hz which is 2 under the box tuning, but the knob shows 0 and 50hz, so i dont know where to turn it to. thnx guys!

yessir

Ahahaha alright will do. i'll take your word and use 0.75

thnx! looks like im gonna be using 0.75 but just wondering why not to use the 0.50 if its held together tight ?

alright. thank you !!! how deep is the port until the 2 Port length ?

I was also wondering if its true that when you put the sub in it adds about 2 hz to the box tuning ? not sure if thats true ive had the same problem.. it told me to make a port longer than the actual box was lol.. i think if its 0.75 they always add 1.5 inches to the port for some reason thnx for your help! sorry for stupid questions.. im just starting to learn more about the whole car audio world. PS what would you recommend for bracing ?

ya i noticed that right after i replied.. sorry about that how off is the RE calculator ?

thanks a lot ! really appreciate the help. Is that with 15 or 14" depth for the box and still 28 wide? thnx again
